MADISON (WKOW) - The National Weather Service has issued a winter weather advisory for Adams, Columbia, Crawford, Grant, Green, Jefferson, Lafayette, Richland, Rock and Walworth counties from 6 am to noon.
A weak low pressure system is developing over the Central Plains. As it moves into the Upper Midwest, a little freezing drizzle is expected.
A light glaze is possible during or after the morning commute, so use extra caution.
It may mix with snow farther north with an inch or less of accumulation possible.
Highs will be around freezing.
As our system departs, high pressure moves in from Canada allowing cold air to spill into our region.
Lows will get to the single digits, but with a breeze out of the NW up to 15 mph, wind chills will range from -5 to -10 by early Thursday.
A cold set up with high pressure developing will keep temps in the mid teens by the afternoon.
It will be plenty bright with partly to mostly sunny conditions.
We start off quite cold again in the single digits, but quickly warm to the upper 20s as a storm system develops over the Central Plains.
Snow will develop by late-day from west to east, overspreading the region by the evening commute.
Snow will fall at its heaviest late evening and overnight. A warm front ahead of the main low may push into our stateline communities.
If this happens, snow may change-over to a wintry mix for a time Friday night and early Saturday morning.
Light snow will taper in the afternoon, but it'll be breezy causing some blowing and drifting.
This still has the potential to bring high snow totals and winter storm conditions to southern Wisconsin, so stay tuned as your Storm Track team updates the forecast.
