...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected through tonight.

...Synopsis and Discussion...
Surface high pressure will remain over much of the central CONUS
today, as a cold front clears south FL and the Keys. Dry and/or
stable conditions will prevail for a large majority of the CONUS,
with minimal thunderstorm potential. One possible exception may be
across parts of the central Rockies as a shortwave trough moves over
this region through the afternoon. Still, with limited moisture
present, overall thunderstorm potential should remain less than 10
percent across this region.
