Heat and Thunderstorm Reminders

[7:50 P.M. Friday, July 3] A line of strong storms is impacting east Iowa and west-central to northwest Illinois. These storms have a history of producing frequent lightning, heavy rain, gusty winds up to 60 mph, and small hail. Prepare for these storms to slowly drift south and east through the evening. When thunder roars, go indoors!

Scattered storm development (30-60% coverage) is expected this evening into the overnight hours. Some of these storms could become strong-to-severe, producing isolated damaging winds and hail. Main concerns though are frequent lightning and localized flash flooding.

Best estimate on storm development and arrival times this evening into tonight with greatest coverage starting near the Highway 20 corridor and sinking southeastward through the early morning hours.

An Extreme Heat Warning remains in effect for areas along and south of Highway 34 through 10 PM this evening with heat indices in the low-to-mid 100s. While there are no heat headlines for Saturday, heat indices are still expected to be in the 90s for most of the area, so remember to drink plenty of water and have ways to stay cool when outside.

Here are some reminders on how to protect yourself from the heat and sun and be prepared for thunderstorms!
