DES MOINES, Iowa – Residents across Iowa are bracing for severe thunderstorms tonight, with the National Weather Service (NWS) in Des Moines warning that large hail will be the primary threat after 6 p.m. Sunday. Forecasters caution that storms are expected to intensify after sunset, raising risks for vehicles, crops, and rooftops.
Hail and Storm Timing
According to NWS meteorologists, isolated severe storms are likely to form in central and northern Iowa late Sunday. As the evening progresses, storms will strengthen, producing hail large enough to cause property damage. Farmers in northern counties may see crop damage if hail cores move across fields.
The agency also warns of quick bursts of heavy rain, which could create localized travel issues. Evening commuters should allow extra time and prepare for sudden low visibility.
Wind Threat Increasing Monday
The severe weather risk does not end tonight. On Monday, September 22, damaging winds become a greater concern as storms continue to sweep across the state. The NWS has placed much of Iowa under a Level 1 “marginal risk” for severe weather, with repeated rounds of storms possible into midweek.
This unsettled pattern could bring multiple rounds of rainfall, raising concerns about ponding on roads and weakened tree limbs that could fall under stronger gusts.
Preparation and Safety Guidance
Officials are urging residents to take protective measures before storms arrive:
- Move vehicles into garages or covered parking to reduce hail damage.
- Secure outdoor items such as patio furniture, trampolines, and grills.
- Check weather alerts frequently through the evening and overnight hours.
- Avoid driving during peak hail activity, as even small hail can crack windshields or cause accidents.
Looking Ahead
Meteorologists expect storm activity to linger into Tuesday and Wednesday, though the strength of future systems remains uncertain. Residents are encouraged to remain weather-aware and ready to adjust plans quickly…
