Severe Thunderstorm Risks and Heat Wave Impact Midwest and Western U.S.
• The National Weather Service (NWS) has issued a slight severe thunderstorm risk for southern Iowa and the Upper Great Lakes, with isolated storms capable of producing large hail and damaging winds.
• A broader marginal risk extends across southern South Dakota, northern Nebraska, the Ozark Plateau, the Ohio Valley, and the Mid-Atlantic.
Impact & Risks
The severe weather poses risks to agricultural regions, particularly in southern Iowa and the Upper Great Lakes, where prime corn-growing areas could be affected by hail and strong winds. The heat wave in the Southwest and Intermountain West increases the risk of heat-related illnesses and wildfires. Persistent dryness in Arkansas and the Mid-South is raising concerns for crop health, as flagged by the Weather Prediction Center (WPC).
