Iowa Weather: Severe Rain & Storm Risk Today – Level 3/5

Severe thunderstorms are expected to develop across Iowa today and Friday, bringing the potential for tornadoes, damaging winds, and large hail. A Level 3/5 elevated risk for severe weather is in effect for southeastern Iowa, according to the Storm Prediction Center.

Today’s storms are expected to develop as a low-pressure system and warm front move into the state. Rain will continue through approximately 2 PM. The low is forecast to track over Waterloo, resulting in a significant temperature contrast across the region. Temperatures will range from the 60s and 70s south and east of the low to the 40s and 50s under and northwest of it, creating a nearly 30-degree temperature spread.

The greatest threat for severe weather will be to the east and south of the low, where warmer temperatures and increased instability are expected. Storms could develop between 3 PM and 8 PM, with the possibility of tornadoes – some potentially strong (EF-2 or higher) – and damaging wind gusts exceeding 70 mph. Hail up to quarter-sized is also possible.

Tonight, rain and storms are expected to diminish quickly, followed by mostly cloudy skies and cooling temperatures. Lows will fall into the low to upper 30s, with a wind shifting from west to east at 5 to 15 mph.

Friday’s Forecast

Friday also carries a Level 3/5 severe risk, with scattered thunderstorms expected in the afternoon and evening. A similar system to Thursday’s will spark storm development, with all hazards – tornadoes, damaging winds, and large hail – possible. Storms are expected to continue into Friday night before tapering off, with timing between 7 PM and midnight. Highs will be in the 50s and 60s, accompanied by gusty southeast winds.

The National Weather Service’s Des Moines office is providing severe weather decision support, including current hazardous weather outlooks, storm reports, and radar information. Residents are encouraged to stay weather aware and trained storm spotters are being sought for this spring.

Looking ahead to the Easter weekend, Saturday is expected to be cloudy, windy, and cool, with highs in the mid-40s and a west wind at 15 to 25 mph.

“The greatest threat for severe weather will be to the east and south of the low where temps are warmer and there is more instability for storms to redevelop off of the cold front.”
