SPC Issues Enhanced Risk for Severe Thunderstorms Across Central Plains on Saturday

The Storm Prediction Center (SPC) has placed portions of the Central Plains, including parts of Kansas and Nebraska, under an Enhanced Risk of severe thunderstorms for Saturday, June 20, 2026. The primary hazards include large to very large hail, damaging winds exceeding 121 km/h (75 mph), and tornadoes, which are possible from the afternoon into the evening hours. This forecast is tied to an evolving synoptic pattern with strong lee cyclogenesis and strengthening low-level flow, creating an environment favorable for organized severe thunderstorms.
