11PM Day 1 Convective Outlook for Wednesday, January 21. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
Widely scattered thunderstorms are expected across parts of the western and central Gulf Coast states this afternoon and evening.
DISCUSSION
A long-wave cyclonic flow pattern will be in place today across the U.S, as an embedded mid-level shortwave trough moves across the south-central U.S. At the surface, a cold front will advance southeastward into the western and central Gulf Coast states today. Ahead of the front, low-level moisture and instability will be sufficient for isolated to widely scattered thunderstorms. However, no severe threat is expected to develop. Elsewhere across the continental U.S., thunderstorms are not forecast today or tonight.
