NO SEVERE THUNDERSTORM AREAS FORECAST

Severe thunderstorms are not expected on Thursday.

Synopsis

An upper ridge will build over the CONUS east of the Rockies while a mid-level trough amplifies over the Pacific Northwest on Thursday. Surface high pressure and accompanying subsidence will limit thunderstorm development over most places east of the MS River and over the Intermountain West. However, weak surface troughing and subsequent low-level moisture return will promote some thunderstorm potential over the central and southern Plains within a warm-air advection regime. A couple of thunderstorms are also possible over portions of the FL Peninsula given the presence of a warm, moist boundary layer. Lastly, a couple of lightning flashes are possible along the shoreline of the Pacific Northwest late Thursday night into early Friday morning. However, buoyancy appears too scant to support enough lightning coverage for the introduction of a General Risk area.
