|Winter Weather Advisory area in purple - see text for details|
I've pasted the text of the Advisory from the NWS below. However, in our estimation, we feel that this is a very conservative forecast based on continuing disagreement among the computer models and issued for an area larger than the metro where conditions could be worse than they are locally.
In the metro (from Crittenden to Fayette County east to west, and from Tipton to Tate County north to south), these are the impacts:
Period of chief concern: noon-6pm today
Main precipitation types: freezing rain or sleet
Intensity of the precipitation: very light to light (0.01-0.05")
Chance of precipitation: 40%.
Temperature during potential precip: 31-33 degrees
Expected impacts: minimal, mainly on elevated roadways and exposed surfaces, such as power lines, due to a potential light glazing of ice. Ground temperatures from recent warmth should keep (non-elevated) roadways from becoming hazardous
Plan ahead, especially for your afternoon commute. Have an ice scraper in your vehicle today. Allow extra time for travel and, if precipitation has fallen or is falling, leave plenty of distance between you and other vehicles and do not make sudden lane changes or brake quickly. Icy spots can come up quickly and with little warning.
There will be a lull in the precipitation this evening and most of the overnight hours. Another round of precipitation will be possible Tuesday, with most of that falling from mid-morning to afternoon when temperatures are expected to be above freezing. Some of this precipitation could also start off as very light freezing rain early Tuesday morning.
