Multiple rounds of storms possible Tuesday, some severe

Severe thunderstorm watches are in place to our north and northeast as a potent Mesoscale Convective System (M.C.S) slides into eastern Wisconsin and Lake Michigan. While the Stateline missed out on the brunt of this line, storms are back-building off it's backside across southwest Wisconsin. Currently, these are non-severe, though are producing 40 mph winds and nickel size hail as they slowly push east towards Green, Rock, and Walworth County. Storm chances with the first round will remain possible into the mid to late morning hours.

A secondary round looks possible late this afternoon into the evening as our next cold front slides in from the north and northwest. 

As of this morning, the Storm Prediction Center has areas between Janesville and Rochelle under a level 1 Marginal Risk while leaving areas south of Rochelle under a level 2 Slight Risk. High CAPE, modest shear, and high moisture will allow additional storms and clusters to develop, posing a risk for damaging winds and heavy downpours. 

A few showers and thunderstorms will remain possible into the early stages of tonight. However, conditions dry out and become less humid as high pressure settles in behind today's cold front. Partly sunny skies will be in place both Wednesday and Thursday, with highs peaking in the low 80s. Rain and storm chances quickly return Friday, which will help cool highs back into the 70s.
