Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0624 AM CST Wed Jan 21 2026
Valid 211300Z - 221200Z
...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.
