Thunderstorms are not expected on Saturday. ...Synopsis and Discussion... Surface high pressure should be centered over much of the eastern CONUS on Saturday, with rich low-level moisture remaining offshore from the Atlantic and Gulf Coasts. A shortwave trough should move from the West Coast to the Rockies through the period, but instability is expected to be too meager for lightning flashes. Accordingly, thunderstorms appear unlikely across the CONUS on Saturday. ..Gleason.. 02/18/2021
