Storm chances quickly ramp back up following a beautiful Monday

Surveys conducted Sunday by the National Weather Service confirmed 5 tornadoes across southern Wisconsin, including the EF-2 tornado that struck the south side of Janesville. 

Additional information is expected to come about today as surveys continue. Stay tune! 

 

Fortunately, the work week kicks off on a quiet note as high pressure moves overhead. Expect partly sunny skies with highs in the upper 80s. Humidity won't be too much of an issue as dew points this afternoon look to sit in the upper 50s. 

Overnight, our attention will then shift to what occurs to our northwest this evening. An impulse sliding into the state of Minnesota will help spark up a strong line of showers and storms, one of which will take aim at the Stateline early Tuesday morning. 

As of this morning, lots of uncertainties remain including the strength of said M.C.S and where it will eventually end up. In fact, forecast models show a couple of scenarios playing out.

Scenario #1, storms roll through the area early, posing a risk for damaging winds and heavy downpours. This would push the better atmospheric parameters south of the region, resulting in no evening threat. 

Scenario #2, there's enough time between the early-day round and the evening round for the atmosphere to significantly recover. This would increase our chance for severe storms Tuesday evening, with all hazards being on the table. 

Scenario #3, storms back build off the the morning M.C.S and sit over N. Illinois for a good chunk of the morning hours. This would also play a role in limiting the afternoon and evening threat. All in all, monitor the forecast and make sure you have multiple ways to get watches and warnings. 

The Storm Prediction Center has the Stateline under a level 2 of 5 Slight Risk for tonight and Tuesday. Again, the Slight Risk for Tuesday may change as more details come about. The cold front responsible for Tuesday's severe threat will also be responsible for the cooler and quieter times that follow. Wednesday and Thursday feature party sunny skies, lower humidity, and highs on either side of the 80-degree mark. Friday would be the next day to monitor for storm potential.
