Stormy Nights Ahead

Currently watching storms that have developed in northwest Iowa march east this morning. The complex is holding together enough, that we will have to watch for a few showers and storms this afternoon. The complex will be on the weakening side of things this afternoon. Temperatures for the first day of summer, will be near average at 82° this afternoon.

A higher chance for storms arrives this evening with an incoming warm front. The Storm Prediction Center has highlighted portions of northern Illinois and southern Wisconsin under a slight risk for strong to severe storms. Storms will develop west ahead of the warm front and will head east. A strong low level jet will develop tonight and will focus the heaviest rain north into southern Wisconsin.

There could be a few showers and storms lingering into Thursday morning, before the warm front passes north into central Wisconsin. Thursday we will be under the warm sector of the system, and this will bring hot and humid conditions with highs in the upper 80's and heat index values climbing into the low to mid 90's. Another round of storms arrive Thursday night into Friday with the system's cold front diving southeast. Again there is a slight risk for severe storms Thursday night into Friday. Threats would include hail and strong winds, along with heavy rain. The front will pass Friday
afternoon and the rest of the day will end of being dry, but it will be much cooler behind the front. We'll be sitting in the 70's through the weekend.
