Storms and Heavy Rain Today & Tonight

Storm Potential Friday and Independence Day

Heat and Severe Weather Reminders

Widespread thunderstorms are or will be impacting the Highway 20 corridor in Iowa and the Highway 30 corridor near Cedar Rapids. Repeated rounds of storms will pose a flash flooding threat this evening with a few of these storms being strong-to-severe. Isolated storms could develop along a gust front near the I-80 and I-88 corridors, but the severe potential with these storms will be low.

Dangerous heat continues along and south of Highway 30 through this evening with forecast heat indices between 100 and 105 degrees. An Extreme Heat Warning remains in effect for these areas through 10 PM today, and areas along and south of Highway 34 will retain an Extreme Heat Warning through 10 PM Friday. Stay hydrated by drinking plenty of water and take frequent breaks in the shade if you plan to be outdoors. Stay cool!

Scattered storms are expected this evening through early Friday morning, with the greatest chances (60-80%) along and north of Highway 30. Severe storms will be possible with damaging winds and heavy rain, and hail and isolated tornadoes cannot be ruled out. Flash flooding will also be possible, especially along and north of Highway 20.

There will be additional chances of storms Friday and again for Independence Day. There is now a Level 2 of 5 risk for severe storms over much of the local area Friday, with a Level 1 of 5 for some on Saturday. There remains quite a bit of uncertainty on the timing and coverage of these storms, but any severe storms will be capable of damaging winds, with a lower threat of large hail and isolated tornadoes.

Here are some reminders on how to prepare for and what to do during extreme heat and severe storms!
