Few snow chances arise ahead of the coldest air of the season

ALERTS: Tuesday will begin with dry with lots of sun, though we can expect cloud cover to increase as the afternoon progresses. This is due to our next clipper system which models show arriving overnight into the early Wednesday. Ahead of this system, the National Weather Service has issued a Winter Weather Advisory for counties hugging the Illinois/Wisconsin border. This will begin late this evening and last until 6AM Wednesday.

TIMING: Fortunately, this will not impact the evening commute as scattered light snow should start to move in after 8/9PM. The snow will be light but with temperatures in the teens, we'll likely see it fluff up between 1-3", with the highest amounts occurring near the Wisconsin/Illinois state line. An isolated 4" total or two cannot entirely be ruled out.

  

While snow chances look to wrap up before the morning commute, travel impacts are likely. Similar to Monday, it may be a good idea to give yourself a little extra time for your travels. 

 

 

AFTERMATH:  Behind the departing low, winds take a turn to the south and southwest, which will allow temperatures to climb into the upper 20s. That will feel like a heat wave compared to what's to come. A strong cold front will swing through Wednesday evening, bringing another batch of scattered snow showers to the area. However, the bigger weather headline will be the brutally cold Arctic air that spills in behind the frontal passage.
