Frosty start, sunny finish—But storms lurk tomorrow

Frost Advisory:

Frosty morning have been a familiar theme lately - but hopefully this one serves as a final reminder that spring is still settling in. Currently, areas across southern Wisconsin along with Jo-Daviess and Stephenson County in northern Illinois are under a Frost Advisory until 8AM. 

  

After a chilly start to the day, sunshine takes over, allowing temperatures to climb to seasonable cool but pleasant levels. Winds will be much calmer compared to recent days, though a light northeast breeze will keep afternoon highs capped in the low 60s. All in all, its a textbook spring day, crisp early with bright and pleasant conditions later on. Cloud cover will increase overnight tonight as our next system approaches the area from the northwest.    

Tuesday's Severe Threat: 

Tomorrow will be warmer, though our weather will turn a bit more unsettled. Skies will turn mostly cloudy and winds will increase as this storm system enters the western Great Lakes. While not everyone will see rain, a few of these storms could become strong to severe, so it's worth staying weather-aware as the day progresses.  

 

In their latest round of severe outlooks, the Storm Prediction Center placed a majority of the region under a level 1 of 5 Marginal Risk. Any thunderstorm that does manage to become severe will be capable of large hail initially, with damaging winds and heavy rainfall as secondary threats.
