⚠️ Wednesday Severe Weather Possible ⚠️
Wednesday is shaping up to be a day to watch closely across portions of Iowa as the potential for severe thunderstorms continues to increase.
A surge of warm, humid air is expected to move into the state Tuesday night into Wednesday, creating an environment favorable for thunderstorms. Current forecast guidance suggests storms will likely develop late Tuesday night and continue into Wednesday morning.
Additional thunderstorms may develop Wednesday afternoon and evening, although confidence in that portion of the forecast is lower right now. How the Wednesday morning storms evolve will play a major role in determining whether the atmosphere can recover enough to support another round of severe weather later in the day Wednesday.
The Storm Prediction Center currently places a large portions of Iowa in a level 2 of 5 (Slight Risk) for severe weather on Wednesday. If storms can fully take advantage of the expected environment, hazards could include large hail, damaging winds, and a few tornadoes.
There are still several days to fine-tune the forecast, and the details regarding timing, storm coverage, and the highest-risk areas will likely change. We encourage everyone to continue checking back for updates as we get closer to Wednesday.
