After an unexpected risk for severe weather was posted for much of Iowa today two days ago, that risk is now gone. As expected, a powerful high pressure system to our east is preventing a storm system stalled in the Dakotas from pushing into Iowa.
That means another round of severe weather is possible today and tomorrow to our west. Showers and thunderstorms are possible in western Iowa tonight, but no severe weather is expected.
Instead of severe weather, Iowa will continue to warm up to well above normal temperatures. Parts of Iowa should reach the 90 degree mark. With dew points in the 60’s and 70’s it’s going to feel warm and muggy across the region.
As for our next chance for organized severe weather, that could come on Tuesday. Right now there is a minimal risk posted by the Storm Prediction Center, but it bears watching depending on the strength of the storm system and whether it can break through a possible cap over Iowa that day.
As for the ridge effectively keeping storm systems away from Iowa, we could see that begin to break down sometime around the Memorial Day holiday. Of course it’s too far out to tell if this would affect plans for the long weekend or bring Iowa the threat of severe weather. We’ll monitor that threat and keep you posted on any changes in Tuesday forecast as it draws closer.
