Friday is shaping up to be another hazy, hot and humid day in the Rockford metro area. Temperatures are again forecast to be in the middle 90s, potentially the hottest so far this year. The heat is to be short lived though as a low pressure system over the Upper Peninsula of Michigan and trailing cold front across northern Wisconsin will push through Northern Illinois late this afternoon/evening. With ample moisture and heat the atmosphere appears primed to erupt with showers and thunderstorms, some strong to severe with the primary threat being high winds, hail and torrential downpours.
Although the severe weather is not welcomed, the chance of rain will be as we have not seen measurable precipitation in Rockford in over a week, since 1.39 inches of rain fell on August 22nd. In fact, Rockford has seen measurable rain on only 5 days so far this month adding up to a total of 2.72 inches for the month, which is over an inch and half below normal! After tonight our only real chance of rain through middle of next week will be on Sunday night.
After the front passes late tonight, Saturday is looking mostly clear and cooler, with temperatures in the 80s. Saturday morning might start of a little cloudy and foggy, but the low clouds and fog should burn off by the late morning hours. Sunday temperatures will rise to the mid 80s again and it will be humid. A 40 % chance of thunderstorms exists during the afternoon hours as a strong cold front will push through the region and end our late season heat wave.
Labor Day looks absolutely beautiful right now. Mostly sunny skies, cooler temperatures in the mid 70s and less humid conditions will exist. Tuesday through Thursday of next week looks very pleasant. Temperatures will be near or slightly above normal with highs in the lower 80s and overnight lows in the upper 50s.
