Scattered severe thunderstorms are possible across parts of the Mid-Atlantic states this afternoon into the early evening. Strong to severe gusts (50-65 mph) capable of wind damage will be the primary hazard with the stronger thunderstorms. ...Mid-Atlantic/Ohio Valley... An upper-level trough over the Great Lakes will move southeast towards the upper OH Valley/Mid-Atlantic states during the period. Water-vapor imagery this morning shows a lead disturbance over southern OH moving east across the central Appalachians. In the low levels, an analyzed frontal zone has been modulated by ongoing showers/thunderstorms and it will move southeast today. A moist airmass ahead of the front, featuring dewpoints in the upper 60s to lower 70s F, will gradually destabilize through early afternoon. East-southeastward moving clusters are forecast to evolve by later this afternoon. Scattered strong to severe gusts (50-65 mph) capable of wind damage will be the primary risk with the stronger thunderstorms, although marginally severe hail may accompany the stronger cores this afternoon. ...Southern ID into eastern OR... A belt of strong easterly mid-level flow will remain over southwest ID into southeast OR to the north of a stationary, deep-layer cyclone over the Sierra Nevada. Heating of an adequately moist boundary layer will steepen low-level lapse rates by early afternoon. Widely scattered to scattered thunderstorms are forecast to develop this afternoon. Forecast hodographs show 20-45 kt 700-500 mb flow (strongest over southeast OR) and mean storm motions 35-45 kt. These flow fields coupled with evaporatively cooled downdrafts will likely result in a mix of quickly moving cells and smaller-scale linear clusters. This activity will potentially be capable of severe gusts (60-75 mph) before diminishing by mid-late evening. ...Western Great Lakes... Northwesterly mid-level flow will be in place across the western Great Lakes today, as a shortwave trough moves southeastward across the region. At the surface, a pocket of maximized low-level moisture will be located over Wisconsin, where MLCAPE is expected to peak in the 1500 to 2500 J/kg range. An isolated risk for large hail/damaging gusts are possible with the stronger thunderstorms. ...Southern Texas Panhandle/West Texas/Far Western Oklahoma... Somewhat displaced from an expansive overnight MCS along the TX coast, an airmass featuring upper 50s to lower 60s F dewpoints will destabilize beneath a weak mid- to upper-level trough. Widely scattered to scattered storms are forecast to develop by late afternoon and aggregate into small clusters this evening. Isolated large hail/severe gusts are the primary severe hazards. ..Smith/Weinman.. 05/27/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
