1017 AM CST Wed Dec 13 2023

Valid 131630Z - 141200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated thunderstorms are possible through tonight from the Four
Corners into west Texas, and across parts of south Florida. Severe
storms are not expected.

....Synopsis/Discussion...
A closed mid/upper-level low will continue eastward over the Four
Corners area and southern Rockies through tonight, removed from a
more progressive belt of westerlies over the northern tier of the
CONUS and Canada. Steepening lapse rates and ascent ahead of the
aforementioned upper low will support isolated thunderstorm
potential from northeast Arizona/southeast Utah into New Mexico
especially tonight, while other thunderstorms will be possible today
and tonight farther east across eastern New Mexico and western Texas
within a persistent warm advection regime.

Additionally, a few thunderstorms will be possible across/near south
Florida near a convergence zone where a moist air mass persists.
