...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not forecast across the U.S. today or tonight.
...Synopsis and Discussion...
Large-scale upper troughing will remain dominant over the central
and eastern CONUS through the period, with multiple embedded
mid-level shortwave troughs progressing over the southern/central
Plains, MS Valley/Midwest, and Southeast. At the surface, a cold
front will continue moving southeastward off the central Gulf Coast
today. Even with gradual low-level moisture return/airmass
modification forecast across parts of the southern FL Peninsula and
Keys, poor lapse rates aloft are expected to limit thunderstorm
potential ahead of the front through tonight.
