THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN AND CENTRAL HIGH PLAINS

### SUMMARY

A few strong to severe thunderstorms with hail and wind remain possible across parts of the northern High Plains into the Central Plains through evening. Isolated strong storms may persist across Maryland and northern Virginia through early evening with strong wind gusts.

Central/Northern Plains

Scattered storms persist this evening across the northern and central high Plains aided by moist southeasterly surface winds and a low-amplitude shortwave trough moving across WY. The most intense areas of ongoing storms were across the Black Hills as of 01Z, with a few strong storms over northeastern CO as well. 00Z soundings across the region show marginal instability profiles, but lack of any appreciable capping inversion suggests storms will persist for several more hours as they propagate slowly southeastward, supported by a increasing low-level jet. Additional sporadic development is possible this evening across KS and OK where the most unstable air mass resides. Scattered cells were already developing over southwest KS in proximity to a hot air mass to the south.

MD…northern VA

A few strong storms persist early this evening along a cold front across parts of MD and northern VA. 00Z soundings continue to show moist, unstable profiles immediately ahead of these storms with generally weak shear. However, a relatively cool air mass from earlier outflow exists across parts of the Delmarva, suggesting storms will diminish.
