Those improvements are set to carry on into Friday, especially during the daylight hours. Conditions will remain dry under a mix of clouds and sun, with highs falling short of the 60° mark by 1°.
Cloud cover does increase shortly after the evening commute. This is all thanks to a lifting warm front that will also contribute to the likelihood for showers and storms. These will initiate over eastern Iowa, spreading over N. Illinois and S. Wisconsin during the evening and overnight hours.
Most will end up under severe criteria, producing heavy downpours and lightning. However, hail will be possible with the strongest updrafts. That is why the Storm Prediction Center has placed a majority of the Stateline under a level 1 of 5 Marginal Risk. Rain chances carry on into the early morning hours of Saturday, though should come to an end prior to daybreak. From there, we can expect cloud cover to hang tight into Saturday afternoon, with temperatures peaking in the upper 50s.
A sprinkle or light shower will be
possible around the lunch hour, though rain chances will start to become likely once again by Sunday night.
Forecast models carry these rain chances into the start of April as another potent storm system glides through the Midwestern states.
One that will bring a more significant threat for severe weather across Oklahoma, Kansas, Arkansas, and Missouri. The severe threat locally will all depend on how far north the warm front ends up.
For the time being, guidance keeps this warm front south of Interstate 80, landing us on the more stable side of the boundary. This will leave winds blowing off of Lake Michigan, placing highs near the 50° mark Monday. Conditions will progressively dry out as we enter the middle of the week. Expect highs to cool slightly, landing in the upper 40s both Tuesday and Wednesday!
