Cold snap coming

Though we've had some cool mornings so far this fall (today is no exception - low of 37 at the weather station in Bartlett this morning), the first real Canadian express cold front of the season is on track for an early evening arrival on Sunday. No precipitation (in fact no real cloud cover) will accompany the front, but its passage will be immediately noticeable as the winds switch to the north and gust to 15-20 mph and temps start falling after 6pm Sunday. So after a very nice Sunday afternoon with highs in the lower to mid 70s, I expect that we'll drop perhaps 20 degrees during the evening hours!

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.
