Monday's Weather Impact Scale: Medium (Orange, 2 out of 4).

Rain, rain/mix and snow will impact different parts of the area this afternoon and evening. Moving forward, the heaviest snow will likely fall north and northwest of Madison or places closer to central Wisconsin. Falling rain/snow and wet, slushy and/or snowy roads will impact the afternoon/evening commute.

WINTER WEATHER ADVISORY will be in effect for Columbia, Green Lake, Marquette and Sauk Co., WI until 9PM Monday. With this advisory, snowfall accumulations will likely range from 3-6”.

WINTER WEATHER ADVISORY will be in effect for Adams, Crawford, Juneau, Richland and Vernon Co., WI until 12AM Tuesday. Within this advisory, snowfall accumulations will likely range from 3-6”.

Tonight's Weather Impact Scale: Low (Yellow, 1 out of 4). The wintry mix of precipitation will move east of the area after midnight. With temperatures dropping well below freezing overnight, any moisture on the roads could freeze and turn to ice.

A messy Monday is already underway! Snow has been falling across southern Wisconsin for several hours Monday morning. So far, the warm air has stayed just south of the area. This why most of the precipitation that has been falling has been mostly in the form of snow. Luckily, temperatures are near the freezing mark, so most of the roads are wet and slushy rather than snow covered.

The precipitation will continue to expand across the entire area this afternoon and evening and have a big impact on your commute home. With temperatures expected to warm this afternoon, the snow will transition to a cold rain or a rain snow mix. Places closer to the WI-IL will likely going make the transition to a cold rain this afternoon. Madison and the rest of the I-94 corridor will likely make the transition to a rain/snow mix. With a cold rain or rain/snow mix expected, roads ways in Madison and places closer to the WI-IL border will likely be more wet/slushy than snow covered.

Places north and northwest of Madison or closer to central Wisconsin will likely see the most snow. This is where 3-6" of snow could accumulate and where traveling will come the most difficult because of snow covered roads.

The wintry mess will continue through the evening and start to taper off from west to east across the area after midnight. Temperatures are expected to drop well below freezing tonight. Any water still on the roads overnight will turn to ice.

Tuesday is going to be a colder day, but it won't be nearly as messy. Highs on Tuesday will be in the mid to upper 20s. Expect decreasing clouds throughout the day.

The middle of the week is looking COLD, even for this time of year! Another blast of ARCTIC air will impact the area. Highs on Wednesday and Thursday will be in the mid to upper teens. The coldest temperature readings this week will come Wednesday night into Thursday morning. Subzero temperatures are expected for most of the area during this time. Wind chills Thursday morning will likely range from -15 to -5 degrees.

Arctic air will not last long. Temperatures will quickly rebound. By Friday, highs will be near or just above freezing.

From this distance, the upcoming weekend looks great! Expect a fair amount of sunshine and highs near or just above 40 degrees on Saturday and Sunday!
