ROCKFORD (WREX) – A couple of rounds of storms will bring an end to our recent heatwave, but will also, unfortunately, bring threats of severe weather and flash flooding.
One area of strong to severe thunderstorms hit the Stateline early in the middle of the afternoon with strong winds and heavy rainfall. These storms will exit by the end of the afternoon. We’ll get a break in the storms until later tonight.
The storms did bring an end to the heat, thanks to rain-cooled air. Rockford dropped 16 degrees, from 95 degrees to 79 degrees, within an hour.
All Excessive Heat Warnings have been canceled, except for Lee and DeKalb counties. These areas will stay under a warning with high heat until 7 pm.
A cold front pushes through by Saturday night. Heavy rainfall and even isolated flash flooding are possible. The elements for a flash flood risk are available thanks to high amounts of moisture and the potential for multiple rounds of slow-moving storms. Avoid any flooded roads as these storms slide through. Blustery winds may be possible with the storms. The t-storm activity should be moving out by Sunday morning. The window for the next round of storms looks to be 3 AM to 7 AM.
Once the front moves by, temperatures and the humidity will be a lot lower. We’ll see highs in the low 80’s (or at least 10 degrees below Saturday), with much lower dew points.
The weather will remain much more comfortable next week. We’ll see a sunny sky throughout the week, so don’t look for rain anytime soon! The humidity stays at a very comfortable level, then starts to rise with the temperature by the end of the week. We’ll go from highs in the upper 70’s early in the week to highs in the upper 80’s late in the week.
