Isolated thunderstorms should occur across parts of east/southeast Texas into the lower Mississippi Valley today and tonight. ....Synopsis and Discussion... Modest low-level moisture will make some inland advancement today across east/southeast TX into the lower MS Valley ahead of a surface cold front as longwave upper troughing persists across the central/eastern CONUS. A low-amplitude shortwave trough rounding the base of the large-scale upper trough should continue to encourage showers and isolated/mainly elevated convection across these areas through tonight. Instability is expected to remain too weak to support severe thunderstorms. ...Gleason/Dean.. 01/21/2026 $$ --- SBBSecho 3.28-Linux * Origin: Capitol City Online (618:250/1) .
