A troublesome storm system setting up shop across the Upper Midwest this week is threatening to produce more severe weather across Iowa later today. Some storms produced large hail across far western Iowa on Wednesday afternoon and evening. Today’s threat looks a little more widespread.
The graphic to the left shows the area under a slight risk for severe weather today. This area is in association with a warm front that’s expected to move from south to north across portions of the state today. All modes of severe weather are possible today.
At this hour it appears the greatest threat for severe weather lies in the Dakotas, but here in Iowa, enough instability should take shape to produce strong to severe thunderstorms this afternoon and evening. One factor that’s keeping the forecast rather muddled is this morning’s storm activity. This will have an impact on the threat Iowa will face later today.
Right now it appears the “window of opportunity” for severe weather here in Iowa may be somewhat short lived and at the very least we do not expect storms to threaten into the evening hours.
We’ll continue to monitor today’s threat and will bring you updates when they are needed throughout the morning. We’ll also bring you live coverage of severe weather across Iowa today should conditions warrant.
Looking ahead, a cap should prevent thunderstorm development for the most part of Friday, with our next chance for strong storms coming Saturday. This threat also looks minimal at this point but still bears watching. Iowa could see a round or two of overnight thunderstorms which can always be a danger on the weekend as many are out and about and not paying as close attention to the threat for strong storms.
