Marginal risk of severe storms in Utah, Ohio Valley
The National Weather Service Storm Prediction Center has issued a marginal risk of severe thunderstorms for northern Utah and eastern parts of the Ohio Valley on Wednesday, September 16, 2026. A mid-level impulse is expected to bring strong winds aloft and steep lapse rates to northern Utah, creating conditions for isolated severe wind and hail. Meanwhile, the Ohio Valley may experience rounds of showers and thunderstorms, with peak heating potentially intensifying storms. Forecast soundings suggest surface temperatures near 70°F (21°C) in Utah and 80°F (27°C) in Ohio Valley, contributing to moderate instability. Overnight, convective initiation is possible in Iowa, though severe probabilities remain uncertain. (Source: NWS Storm Prediction Center, 09/16/2026)
