My web stats for this year show that over 600 of you visited MWN more than 1,400 times on December 15th (the ice storm that narrowly missed Memphis), which is very close to the same number that visited on February 5th (the day the tornadoes roared through the metro area) and March 7th (in the middle of the 4-7" snow storm)! The total number of visits to MWN for 2008 will approach 26,000 by midnight on January 1, 2009!
As for this blog, this is post #161 of the year. By tomorrow night, the blog will have been seen by about 2,700 visitors since I started keeping stats in late July, with over 4,000 pages viewed. Dec. 15-16 were the two biggest days with over 500 visits during that 48-hour period. Once again, I offer my thanks to you for your patronage and encourage you to pass the word on to your friends, family, and co-workers that MemphisWeather.net and The MWN Blog are two sites that every Mid-Southerner needs to have bookmarked as their source for weather information.
Thanks for a fabulous 2008! I already have some tricks up my sleeves for 2009, so don't go anywhere! Happy New Year!

Yesterday's high of 73 was 1 degree off the record here in Memphis. And this morning's balmy low of 67 would shatter the record for highest minimum temp of 59 if we didn't have that pesky front coming through this evening, which will drop the daily low below that record by several degrees. High temps today will be in the mid 70s with a little sunshine. The record is 76, so once again we'll get close. I am expecting 74, but with more sunshine than expected, 76 may be in jeopardy!
We are also under a WIND ADVISORY until midnight tonight as it will be another very warm, very windy day. Wind gusts could approach 40 mph during the daytime hours. Make sure that outdoor objects are buttoned up or you could lose them! Driving high-profile vehicles could also be difficult today due to the wind gusts.
The other note for today relates to the possibility of severe weather as the front passes through this evening. The Storm Prediction Center has placed the metro area under a SLIGHT RISK of severe weather, with the greatest threat being damaging wind and small hail as a squall line passes. The line will likely pass through the city between 6-9pm tonight. Conditions will quickly improve after the front passes, with skies clearing after midnight.
The New Year's week forecast looks pretty good right now with highs generally in the 50s and lows in the 35-40 degree range, which are both slightly above normal. Dry conditions are expected Sunday through New Year's Eve. A frontal system will move through Thursday or Friday (timing of this one is still a little fuzzy), so expect some rain late in the week and cooler temps headed into next weekend.

Fortunately, temperatures won't drop much Monday night as skies cloud up and a chance of precipitation moves in by morning. I'll try and write more on that tomorrow, but right now it appears that there could be a wintry mix possible early on Tuesday before temps warm enough to change it to all rain by mid-morning. Stay up to date with the latest forecast from MemphisWeather.net.

A five mile perimeter. Parking slots for 175 aircraft. 300 miles of conveyor belts. That's the Memphis Super Hub. With over 4,000 employees during the day and 8,000 at night, this unbelievable facility keeps Memphis and FedEx connected any point on the globe. Supporting the largest air cargo fleet in the world, the Memphis Hub handles about 3.3 million packages per day.
The average high temperature on Christmas Day in Memphis is 50 degrees, while the average low is 33. The only Christmas in recorded history (since 1872) that measurable snow fell ON Christmas Day was 3.5" in 1913! A trace of snow was recorded in 1975, 1980, and 1992.
As for snow on the ground on Christmas Day (a white Christmas), the greatest recorded snow depth was 10" in 1963. Other years in which the snow depth was at least 1" on Christmas Day were 1962 (2"), 2004 (2" - remember that one?), and 1998 (1"). A trace was present on the ground in 1966, 1980, and 1990.
Interestingly enough, Jackson, TN, which seems to get all the good weather, has not had a measurable snow on Christmas Day in their recorded history (records date to 1948)...
Christmas Day is in my extended forecast beginning today, so keep an eye on it for our forecast (not climatological) chances.

At Memphis Int'l Airport, beginning last night (Tuesday) at 11 pm local time, temps have been steady or rising each hour. I expect that trend to continue overnight tonight as abundant cloud cover has helped keep the lid on temperatures today and a warm front pushes a little closer to the area overnight. They will continue rising tomorrow, to a high at least in the upper 40s. Thursday night, the warm front should make it all the way through Memphis, so I expect that temps will again hold steady in the evening before rising overnight as a stiff south wind kicks in. By Friday, a little sun might peek through and highs should reach well into the 60s. This would make a stretch of almost 3 days (Tuesday night to Friday afternoon) that temps will have held steady or risen every hour.

Shelby County - OPEN
Memphis City - OPEN
Memphis Catholic - OPEN
Fayette County - OPEN
Tipton County - OPEN
DeSoto County - opening one hour late
Crittenden County - assumed OPEN
Many school districts across west TN, outside of the metro area, will be closed today. Visit WMC-TV (wmctv.com) for the latest information.
Our friends just to the north are not nearly as lucky however, as a major ice storm has hit northeastern Arkansas, southern Missouri, and western Kentucky. Significant accumulations of sleet and freezing rain have fallen (up to an inch in many locations) and it will be a while before they climb back above freezing as the stationary front to the south of MEM takes until Wednesday to lift back that far north.
So what to expect for the city of Memphis and it's suburbs? As I had forecast yesterday, and am still sticking to, chances for precipitation today reside at about 30% and any precipitation that falls will be very light. The temp should rise above freezing at around noon, so it's going to be a cold day and the wind blowing at 15mph won't help. For tonight, things are still a little tricky. It appears the precip chance is slightly higher, but the temps are going to be an issue. They should hold steady in the mid 30s, and that is what I currently call for. However, there is some indication that they could drop back to 32, or perhaps not rise higher than 33-34 during the day, which would mean some areas, particularly outside the city proper, have another shot at seeing light freezing rain. Will hold off on that until we see how today progresses. I should have a better idea on this afternoon's forecast update around 3:00. Things definitely get better on Wednesday with highs well into the 40s - and 60s are expected late in the week before the next big cold front!

Also at 10pm, the I-40 and I-55 bridges across the Mississippi River are at a standstill thanks to a light coating of ice and several wrecks. Check the road conditions links to the right for more info.
I've also added some links to the top right of this blog for area road conditions, school closings, and the latest storm reports from the National Weather Service. The scenario appears to be unfolding as forecast so far. Please exercise caution if you must be on the roads from now until noon tomorrow.
Fortunately (if there is a positive to this event), the amount of precipitation expected during the night in the metro area should be less than 1/4" based on the computer model that seems to have the best handle on things right now. This should limit some of the collateral damage from the ice (like power lines down, branches down, etc.), but will still create hazardous driving conditions late tonight and for Tuesday morning's rush hour, particularly on bridges and overpasses. Pavement temperatures (except bridges and overpasses) are running around 40 degrees right now, so it will take some precipitation falling on the roadways before they collect a glaze - bridges and overpasses are not this warm and will freeze first. Please exercise extreme caution if you must travel prior to about noon tomorrow, when temperatures will be back above freezing.
Be sure to stay up to date with the latest conditions and forecast at MemphisWeather.net.
Shelby County - closing 2 hours early
Memphis City - closing at 1:30pm
Memphis Catholic - closing at 2:00pm
Fayette County - closing at noon or 1:00pm depending on start time
Tipton County - closing at 1:00pm
DeSoto County - closing 2 hours early
Crittenden County - no word yet

The critical temperatures that will be monitored are in the lowest 2-3,000 feet of the atmosphere. Temps above that (up to several thousand feet) will actually remain warm, promoting rain. However, by early afternoon, those low level temps will fall below freezing. As this sub-freezing layer gets deeper, a little sleet could start to mix with the rain after 3pm. Surface temperatures will still be above freezing, but in the 30s. As the surface temperature approaches freezing around 6-8 pm, the potential for freezing rain increases.
Temps will remain around freezing all night Monday night and up until about 9am Tuesday, so any precipitation that falls could freeze on contact from 6pm Monday to 9am Tuesday. Rain amounts are not expected to be significant, but one-tenth of an inch of ice is possible by Tuesday morning in the metro area. This would be enough to coat bridges, overpasses, and other exposed surfaces. For this reason, the National Weather Service has issued a Freezing Rain Advisory for Memphis (and much of the Mid-South from I-40 north) beginning tomorrow through Tuesday morning. The MWN forecast will remain updated on a regular basis throughout the potential winter weather event. Stay tuned!

MEMPHISWEATHER.NET / NWS-MEMPHIS TN
456 PM CST SAT DEC 13 2008
...WINTER WEATHER POSSIBLE MONDAY NIGHT...
THE POTENTIAL FOR WINTER WEATHER EXISTS EARLY NEXT WEEK. A STRONG COLD FRONT WILL USHER MUCH COLDER AIR INTO THE REGION MONDAY. TEMPERATURES WILL PLUMMET AROUND 20 DEGREES IN A SHORT PERIOD OF TIME FOLLOWING THE FRONTAL PASSAGE...CHANGING RAIN OVER TO FREEZING RAIN ON MONDAY NORTH OF THE MEMPHIS METRO AREA.
BY MONDAY NIGHT...THE FREEZING LINE MAY SINK FURTHER INTO THE MIDSOUTH CHANGING RAIN OVER TO FREEZING RAIN FROM MEMPHIS NORTHWARD. THE FRONT WILL BEGIN TO LIFT BACK NORTHWARD DURING THE DAY ON TUESDAY...ALLOWING TEMPERATURES TO WARM BACK ABOVE FREEZING AND CHANGING FREEZING RAIN BACK TO RAIN.
MINOR ICE ACCUMULATIONS ARE POSSIBLE MONDAY NIGHT. IF MORE ICE DEVELOPS THAN IS CURRENTLY FORECAST...ICE ACCUMULATIONS COULD CREATE HEAVY LOADS ON TREE LIMBS AND POWER LINES...POSSIBLY CAUSING THEM TO FALL. IN ADDITION...VERY DIFFICULT DRIVING CONDITIONS MAY DEVELOP. IF ROAD ICING DOES OCCUR...PLEASE REMEMBER TO ALLOW EXTRA TIME TO REACH YOUR DESTINATION.
DETAILS CONCERNING THE EXACT TIMING...LOCATION...AND AMOUNTS OF WINTER PRECIPITATION WILL BECOME MORE CERTAIN AS THE EVENT DRAWS CLOSER. WATCH FOR LATER FORECASTS AND STATEMENTS FROM THE NATIONAL WEATHER SERVICE AND MEMPHISWEATHER.NET.
EAP / KRM
Unfortunately, rain could continue into Monday night and early Tuesday, setting the stage for possible freezing rain during that period. Freezing rain because the temperatures above the lowest 1000 or so feet will be way too warm to support snow or sleet. Freezing rain is defined as rain that falls as a liquid then freezes on contact with surfaces that are below freezing. It is also potentially the most dangerous form of winter weather due to its ability to accumulate quickly, forming a slick coating of ice on bridges, overpasses, trees and power lines, and vehicles. I am not expecting large amounts of ice by any stretch in the Memphis area just yet, but northeast AR and northwest TN should definitely be preparing for this possibility. It's still too early to determine whether the air will be cold enough and enough rain will fall in the metro area to promote accumulating freezing rain.
For the rest of the week, the front will hang around the area all week, continuing the rain chances throughout the week. Models are having a difficult time with its placement and any upper-level waves that might move through, triggering rain events, so you'll just have to stay tuned!
I'll do my best to keep the MemphisWeather.net forecast updated throughout the weekend, and definitely into next week, so that you have the latest and greatest information from the most accurate source in Memphis!

#1. Wow, what a rain! Check out the map below for a look at 24-hour precipitation reports from this morning for the eastern U.S. Note the 1.5-5"+ totals across the Mid-South, Tennessee Valley, and lower Mississippi Valley. These reports come from the CoCoRaHS network of trained precipitation observers. Reports from inside Shelby County are all between 3.50-3.75" while totals to our east are generally about 0.50-1.00" higher! At WXLIVE in Bartlett, the automated weather equipment recorded 2.85", while the manual "official" rain gauge right next to it reported 3.59" for the event. The difference is larger than I usually see between them (usually the automated gauge is ~10% under, depending on the wind). That's still the most rain recorded in one calendar day since WXLIVE was installed in June 2005. The 3.48" recorded at the airport on the 10th was also a record for the date. Wow!!
#2. As cold air filters in today, holding temps in the upper 30s in the metro area, a developing low pressure system over the northern Gulf of Mexico will strengthen and move northeast tonight. The Mid-South will be on the back (cold) side of the low and precip will wrap around the low overnight as it moves northeast. Anything more than a tenth of an inch should remain east and south of the city and there is potential for some accumulating snow in northeast MS and eastern areas of west TN (nearer the TN River). However, in the metro area, expect mainly light drizzle or a light shower with temps in the mid 30s. Some snowflakes could mix in between 3am-10am but no accumulation is expected. Sorry school kids!
What do you have to say about yesterday's rain? How about the chance of snow? Leave me a comment!
Tuesday, December 9, 2008
Following the cold front, much colder air will infiltrate the Mid-South with temps dropping overnight to around 40 by daybreak Wednesday, but not recovering much, if at all, during the daytime hours on Wednesday as a steady northwest wind pours cold air into the region. There is a chance of ...winter weather... (gasp!) Wednesday night/Thursday, again mainly to the south of the city. More on this in an upcoming blog. Stay tuned, and stay dry!

In addition, the passage of the front will signal an end to today's "balmy" 60+ degree weather, with temps dropping up to 15 degrees in the hour or two after the front passes and bottoming out in the morning in the mid to upper 30s! Very little recovery will take place tomorrow with highs in the 40-45 degree range.
Tuesday, December 2, 2008
I'm referring of course to the recent snowfall (or lack thereof in certain areas of the Mid-South). Reports from across the region, including Jonesboro, Jackson, Nashville, Crossville, north Alabama (!), and even as close as Cordova and Arlington, TN, indicate that light snowfall was widespread early Monday morning, and into the afternoon east of the city. I'm glad that those of you who live outside the city got to see some snow, because the airport officially recorded NADA. The city is always right on the line, whether it be the rain-snow line, the precip-no precip line, whatever.
And at my weather station in Bartlett, we also got nada, nothing, zip, zero zilch! My young daughters need to be able to continue to think of me as super-dad - a blown forecast (in their eyes - they didn't see any snow) doesn't help matters. :-) I guess I'll have to go back to fixing their toys and kissing their boo-boos...
So, did you see any snow? Leave me a comment and tell me about it!

Looking ahead, the best rain chances in a while will move in Sunday night as a cold front tracks through the Mid-South. The air behind this front is not nearly as cold, so temps will remain in the 50s to near 60 for highs through much of next week. Right now, another front and associated precipitation move towards the area by week's end. I expect that the rain will likely hold off until at least Thanksgiving night, so while Black Friday may be wet, Thanksgiving should be pleasant.
Todays topic is winter weather safety rules for your home.
The best way to survive a winter storm is to plan and prepare for the hazards of winter weather. Although some winter storms develop quickly and with short notice...most events can be planned for.
At home...the primary concerns are for the potential loss of power...heat and telephone service. Food supplies may also run low if conditions persist for several days. Some items that should be readily available around the home prior to the onset of winter weather include...
-extra food and water...especially canned goods
-a flashlight with extra batteries
-first-aid supplies and extra medicine
-extra baby items
-extra wood for emergency heating
-a battery powered NOAA Weather Radio and portable radio
If power is lost...never use a gasoline or diesel-powered generator inside the house...in the garage...or any other enclosed space. Generators can cause carbon monoxide to build up to deadly levels in enclosed spaces. Operate such generators outdoors only.
Another winter threat is house fires. December...January...and February are the leading months for house fires in this country. More than one-third of fire deaths occur during the winter months.
Here are some precautions you can take...
-central heating systems should be kept in proper working order. This includes regular inspections.
-Space heaters need to be at least 36 inches away from any flammable materials. The heaters should not be left on when no one is present or when people are asleep. The heaters should have automatic shut-off switches that turn the unit off if it tips over.
-Fireplaces and chimneys should be inspected and cleaned on a regular basis. The fireplaces should have a sturdy screen... and only wood should be burned.
-Wood stoves should be installed...used...and maintained in accordance with instructions from the manufacturer. Use of a stove board will protect the floor. Only wood should be burned in the stove.
-Kitchen ranges and ovens...charcoal grills...and hibachis should never be used for heating.
-Carbon monoxide is another hazard. It is a colorless... odorless gas and is produced by gas-fired appliances... charcoal grills... and wood-burning furnaces and fireplaces. Carbon monoxide alarms should be installed to provide an early warning when the gas begins to build up.
This concludes this week's series on winter weather, brought to you by MemphisWeather.net and the Memphis office of the National Weather Service.

The coldest night of the fall is on tap for Friday night! Temps in the "urban heat island" will fall into the mid 20s, while a few spots in rural areas outside the city could see a low in the upper teens Saturday morning! South wind Saturday will help warm it back into the lower 50s by mid-afternoon. The next rain chance doesn't come until early next week, but temps are not forecast to be nearly as cold behind the front early in the week as the past two have been. Normal highs this time of year are near 60 while lows are typically in the lower 40s. Below normal temperatures will thus continue into next week.
Today's topic is winter precipitation types.
Snow -- snow forms in the clouds and remains as snow all the way to the ground. It most commonly takes the form of snowflakes...which are the familiar six-sided ice crystals. It may also fall in the form of snow pellets or snow grains.
Snow flurries are most commonly seen as a few snowflakes falling...although visibilities can be reduced at times. In the Mid-South...the term snow flurries is used to indicate that no accumulation is expected.
Snow showers is a term not often used in the Mid-South. In this type of precipitation...the snow falls at varying intensities over brief periods of time. Accumulation may occur...especially during moderate to heavy snow showers. Blowing snow most commonly refers to snow that is already on the ground and is lifted into the air by the wind.
In the Mid-South...heavier snows most commonly occur when cold air is already in place over the region and a strong upper level low pressure system moves out of the southwestern United States. The low serves to pull moist air northward into the cold air. Light snow or snow flurries can also occur in the cold air that follows the passage of an Arctic cold front.
Sleet - sleet consists of pellets of ice. In fact...for people who have trouble with the difference between sleet and freezing rain...it may be easier to associate sleet with its technical name...which is ice pellets. For sleet to form...snow begins falling from the clouds but then goes through a layer of above-freezing air thousands of feet above the ground. This causes the snow to change to rain. Then...the rain goes through a layer of below-freezing air...usually at least two to three thousand feet thick...and the precipitation turns into pellets of ice.
Sleet typically occurs in a fairly narrow band. This band usually moves...but at times may remain nearly stationary...resulting in accumulations of sleet. In the Mid-South...sleet most commonly occurs in a narrow band between an area of rain to the south and an area of snow to the north.
Freezing rain -- this weather phenomenon is sometimes called glaze...because of the glaze of ice it puts on surfaces at the ground. Freezing rain most commonly occurs when precipitation falls from the clouds as snow...then goes through an above-freezing layer...which turns the precipitation to rain. Then...the rain reaches the ground where temperatures are below freezing. The rain then freezes as it hits exposed objects. In the worst cases...everything becomes coated with a layer of ice.
In the Mid-South...freezing rain commonly occurs as an Arctic high pressure system begins to move away from the state. In this situation...cold air is still lingering at the ground...but warmer southerly winds from the Gulf of Mexico begin bringing moisture back over the top of the cold air. Since the air at the ground has not warmed above freezing...the rain that falls freezes on the ground and other objects. Freezing rain...and its cousin freezing drizzle...often develop during the late night hours...creating icy conditions for morning rush hour.
Freezing fog -- while this is not precipitation falling from the clouds...it is another winter weather hazard. Freezing fog typically develops on clear...calm nights when temperatures are below freezing. Fog forms and freezes...usually on bridges...overpasses...and other elevated roadways. It can create quite a surprise for motorists...due to the presence of clear skies overhead.
Frost -- frost describes the formation of thin ice crystals on the ground or other surfaces in the form of scales...needles...feathers...or fans. Frost forms when water vapor in the air turns directly to ice crystals on an object. The temperature of the object must be below freezing for frost to occur. However...frost is sometimes seen on the ground when official temperatures are reported to be above freezing. This is because the official temperature is taken about five feet above the ground...where the air can be a few degrees warmer than the temperature at ground level.

Today we will focus on winter weather travel tips and safety rules.
Thanksgiving is just around the corner and other holiday travel is coming soon. Now is a good time to focus on winter travel. About 70 percent of deaths linked to wintry weather happen in automobiles. Here are some tips to help from being part of that woeful statistic...
Make checking the latest weather reports part of your travel plans so you can avoid storms. Carry a NOAA Weather Radio along to tune into local weather information 24 hours a day. Fully check and winterize your vehicle before the winter season begins.
Carry a winter storm survival kit in your car. The kit should include ...
1. Blankets or sleeping bags
2. A flashlight with extra batteries
3. A first aid kit
4. A knife
5. Some high-calorie, non-perishable food
6. Extra clothing to keep dry
7. A large empty can and plastic cover with tissues and paper towels for sanitary purposes
8. A smaller can and water-proof matches to melt snow for drinking water
9. A sack of sand or Cat litter for traction
10. A shovel
11. A windshield scraper and brush
12. A tool kit for emergency repairs
13. A Tow rope
14. Battery booster cables
15. A clean water container
16. A Compass and Road maps.
Keep your Gas Tank near full to avoid ice in the tank and fuel lines. Try not to travel alone. Let someone know your timetable and primary and alternate routes.
A last reminder...a Winter Storm Watch means that winter weather is possible...a Winter Storm Warning is when winter weather has begun or is about to begin. Start your preparations now for the safest winter season possible and stay tuned to the forecast.
Tuesday, November 18, 2008
Todays topic is frostbite and hypothermia.
Frostbite causes numbness and white or blue-tinted skin and occurs most commonly in the fingers...toes...ears...and nose.
Hypothermia...an abnormally low body core temperature...is caused by prolonged exposure to cold. Hypothermia can occur indoors as well as outside. Body functions slow to a dangerously low level. Symptoms include slurred speech...incoherence...drowsiness...poor coordination...a slow heart beat...uncontrollable shivering or no shivering at all.
To avoid hypothermia...keep your clothes dry. Wet clothing loses all insulating value and should be changed as quickly as possible.
Mittens and a warm hat are necessities. The body loses about 50 percent of its heat through the head...so whether you are outdoors or inside an unheated home...day or night...a hat will go a long way in helping you stay warm.
Wind chill is based on the rate of heat loss from exposed skin caused by the combined effects of wind and cold. As the wind increases...heat is carried away from the body...driving down the body temperature. Remember that animals are affected by wind chill as well.
Avoid overexertion...such as shoveling heavy snow or walking in deep snow. The strain from the cold and hard labor may cause a heart attack. Wear loose...light-weight...warm clothing in several layers. Trapped air is an insulator. Layers can be removed to avoid perspiration and subsequent chill. Outer garments should be water repellent and hooded. Always cover your head...as you can lose half of your body heat through an uncovered head. Be prepared for the storm by listening to NOAA Weather Radio...commercial radio or television for the latest winter storm advisories.

It's right around the corner! Coming in a matter of days...
The next big addition to MWN will be a Flash-based interactive radar - where YOU have control over what you see. Zoom in to your area, add storm tracks and severe weather warnings, overlay radar-based severe weather indicators, see how much rain has fallen across the area, even see where winter precip is falling!

For next week, another pattern change is coming as we start seeing Gulf moisture flow back into the region and with a very slow moving front and low pressure systems riding up along the front, we will be set up for perhaps more than one bout of moderate to heavy rain. The first comes Monday night and early Tuesday with cloudy skies and slight chances of rain lingering until another possible round on Wednesday or Thursday. Hopefully by Friday, the front will have moved through and cleard everything out in time for the weekend! Next week's rainfall totals could easily surpass 2" in many locations.

Temperatures at Memphis International Airport were slightly below normal for October with an average high of 73.8 and an average low of 53.2. Precipitation was above normal by just over an inch. The airport received 4.34" during what is climatologically the driest month of the year.
As for WXLIVE! in Bartlett, the average temperature was 59.7, which is almost 4 degrees cooler than the airport, thanks in large part to much cooler morning lows that we experience out in the suburbs. Precipitation was almost identical to the airport at 4.32", though my CoCoRaHS "official" rain gauge pulled in an impressive 5.78." It is located right next to the WXLIVE! station. Overall, October really was a great weather month. The pleasant days and cool nights are just what I like!
The week ahead...
The very mild weather of the past several days will continue for a few more as high climb well into the 70s. Low temperatures the past couple of morning have been lower than I expected, even dropping back into the 30s this morning in Bartlett. This is thanks to the very dry air in place and no wind or clouds overnight. As the next storm system draws closer, moisture will increase and a wind of a couple miles per hour will be steady through the night, which should help to keep those lows up a little higher than in recent mornings. Bottom line... great weather is on tap for Election Day 2008 on Tuesday, so make sure you exercise your right to vote, despite the expected crowds. Every vote counts!
The next cold front is due to arrive late Thursday evening. This front will likely bring a round of showers and thunderstorms to the region Thursday afternoon or evening, followed by much cooler temperatures. Highs behind the front will once again be back into the low to mid 60s as we head into next weekend.

As we approach Halloween, temps are warming up as Canadian high pressure is replaced by a warmer airmass. Tonight's lows may still reach the upper 30s in the suburbs, but that should be the last 30 degree readings until at least the middle of next week. Highs are going to be reaching into the lower 70s for the weekend and trick-or-treat weather looks very pleasant - temps in the 60s with a few clouds.
Saturday, October 25, 2008
Then, the coldest air of the season builds in on high pressure originating in Canada for Monday and Tuesday. Monday will be the coldest daytime temps as the mercury tops out in the upper 50s and a brisk northwest wind makes it feel even colder. Morning lows Tuesday and Wednesday will be well into the 30s with a widespread frost and perhaps a couple hours of near or a degree or two below freezing temps each morning. Fortunately, the weather moderates by mid-late week and trick-or-treating weather on Friday night appears to be very pleasant with temps in the 60s under mainly clear skies.

That's when things will change. An upper-level low pressure system will develop at the base (southern end) of a trough now over the Pacific Northwest. By mid-week, that low will strengthen over the Plains and move slowly southeast towards the Mid-Mississippi Valley. The closed low is forecast to affect our region Thursday and Friday (see the image below valid Friday evening and note the concentric black circles and yellow/orange shading over the center of the U.S.). This low will mean plenty of clouds, rain, possibly a few thundershowers, and cooler weather for Thursday and Friday. By Saturday it will pick up speed moving east and we should again see high pressure return for at least the latter half of the weekend and early next week.
The extended range guidance is indicating a more active pattern for late October-early November with below normal temps.

We've now had our break for the day and more storms have fired as a fairly slow-moving, but strong cold front approaches from the west. Current radar indicates a developing batch of storms moving through the metro area and extending south along the MS River. Very heavy rain and likely some small hail is falling from some of these storms. This pattern will continue into the evening hours, before becoming mostly scattered showers overnight. A low chance of rain still exists tomorrow as the upper level trough follows behind the front. At the least, cloud cover will keep temps in the 70s throughout the day. A clearing pattern will commence in the wake of the trough, with partly cloudy skies and warming temps expected Thursday through the weekend.
As for me, I'll be enjoying a warm and dry weekend on the beach with family! Orange Beach, AL is our destination for a fall break excursion to the Gulf Coast. Wish you were me! ;-)

This week, we will have a fairly significant trough move through mid week. Though it's origins in the Pacific mean there is not a lot of cool air behind it, it will pick up on the increasing moisture and bring us our best chance of rain in probably several weeks. Rain and some t'storms will be moving in from the west Tuesday afternoon and evening and it could be fairly wet through Wednesday, before tapering off with the passage of a "cool" front Wednesday night. Conditions look to be dry and warm on the backside of the trough for the end of the week and into the Fall Break weekend - for those who are tied to the local school's calendars.
I'd also like to point out that this is my 100th blog posting since starting several months ago. Thanks to all of my readers for their comments, questions and support! Also don't forget to check out MWN Mobile when you get a chance at pda.MemphisWeather.net!
