This Evening and Overnight Severe Storm Risk

Sunday's Enhanced Severe Storm Risk

Monday's Severe Storm Risk

Scattered severe thunderstorms will be possible late this Saturday evening through Sunday morning. Most of the strong to severe storms should remain in northeast Nebraska and northwest Iowa, generally south of U.S. Highway 18. Some weaker showers and thunderstorms could reach further north into southeast South Dakota and southwest Minnesota. Hail up to the size of quarters and wind gusts to around 60 mph will be possible near and south of U.S. Highway 20. Ensure you have a method to receive possible warnings, especially while you are sleeping overnight into Sunday.

There will be an enhanced risk for strong to severe thunderstorms Sunday afternoon into early Monday morning. While this is conditional on the sky clearing out Sunday morning, there will be a strong probability of storms quickly developing Sunday afternoon. The potential will be present for the strongest cells to produce 2 inch diameter hail, 70 mph wind gusts, and several tornadoes across much of the four state area between 3 pm and 2 am. If you have outdoor plans, have an alternate plan to move inside if weather gets messy. Have multiple ways to receive warnings.

Depending on if the sky can clear out Monday morning after the overnight thunderstorm activity, there will be potential for a third round of strong to severe storms in the east. If the atmosphere destabilizes again, a slight risk of storms producing wind gusts to around 60 mph, and hail up to the size of quarters will exist near and east of Sioux City to Windom. If you have outdoor or travel plans, please monitor your favorite reliable weather information source.
