6AM Day 1 Convective Outlook for Wednesday, January 21. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
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.
