Tuesday should undoubtedly be the warmest day this week followed by some not so pleasant changes in our weather as we head toward the weekend.
Ridging at the surface and aloft is expected to lead to mostly sunny skies Tuesday. Breezy south/southwest winds will blow as well between 10-25 mph with gusts up to 35 mph. This combination of sunshine and southerly winds should push temperatures into the upper 70s for afternoon highs.
This warm up comes ahead of another system upstream that is forecast to dig into the upper plains and move eastward during the day Tuesday. As the shortwave moves toward the western Great Lakes it will push a cold front through northern Illinois.
We'll watch for widely scattered showers and thunderstorms to develop ahead and along the cold front Tuesday night. The chance for wet weather is forecast to hang on for a bit Wednesday, but we should be dry by Wednesday afternoon.
Thursday evening and into Friday another good chance for rain is expected to move into the region. That bout of wet weather is expected to bring much cooler air with it, making for what may be a very unpleasant Friday.
