Showers and thunderstorms will continue to track through eastern Iowa this morning. Locally heavy rainfall will be possible, along with frequent lightning. Storms should exit the area between 10 a.m. and noon, leading to decreasing clouds. It’s going to be hot and humid this afternoon with highs in the 90s and a southwest breeze 10-20 mph.
Heat Index values, what it will actually feel like factoring in dew points in the 70s, will be between 100° and 110°.
Similar conditions are expected Friday and Saturday, leading to an Excessive Heat Warning.
Tonight, the same boundary that’s been producing storms the past couple days will provide another chance of storms. This time, most of the activity should stay into portions of Minnesota and Wisconsin, however some of those could track through northern Iowa. Locally heavy rain and gusty wind would be the primary concerns.
Friday will just be downright hot and humid with lots of sunshine.
Saturday, a cold front tracks into the state. This will provide a chance of storms, especially in northern Iowa. Highs will range from the 80s north, to 90s south.
That front will keep storms in the forecast Saturday night and Sunday. It will bring much cooler air into the area early next week.
