What’s going on
An intensifying upper-level high centered over the western U.S. is working in concert with a storm track digging toward the Pacific Northwest to bring anomalous heat from the Great Basin to the northern Plains. This heatwave is expected to peak this afternoon when triple-digit high temperatures will be common along this corridor.
Where storms may be stronger
Meanwhile, repeated rounds of showers and thunderstorms are expected to continue today across the southern Appalachians to the Carolinas as a couple of low pressure waves undulate along a slow-moving front. The threat of heavy rain associated downpours from thunderstorms continues to pose a slight risk of flash flooding today along this corridor of the eastern U.S. By Monday, the threat of flash flooding is forecast to lessen across the Mid-Atlantic although scattered heavy downpours remain possible over interior Southeast.
Rain concerns
No specific heavy-rain concern is highlighted right now.
Hail potential
National hail guidance is showing 5% Hail Risk today. This is a forecast signal before storms happen; HailMapr storm maps update after hail is detected or published.
