VALID 302000Z - 311200Z
..NO SVR TSTM AREAS FORECAST...
..NRN CA TO SRN WY/NRN CO...
ISOLATED THUNDERSTORMS HAVE RECENTLY DEVELOPED ACROSS NRN UT INTO
SWRN WY ALONG SW-NE ORIENTED BAROCLINIC ZONE. THIS ACTIVITY HAS
CERTAINLY BEEN ENHANCED BY BOUNDARY LAYER HEATING ALONG ADVANCING
FRONTAL ZONE WHERE SFC TEMPERATURES HAVE WARMED INTO THE UPPER 50S
AND 60S. IT APPEARS CONVECTION WILL CONTINUE TO DEEPEN ACROSS THIS
REGION AS LAPSE RATES STEEPEN AND FURTHER THUNDERSTORM ACTIVITY
SHOULD DEVELOP INTO THE EARLY EVENING HOURS AS FAR DOWNSTREAM AS
NCNTRL CO. LOSS OF DAYTIME HEATING WILL RESULT IN WEAKENING OF
THUNDERSTORM UPDRAFTS.
..SOUTH FL...
TROPICAL STORM NOEL WILL DRIFT WWD ACROSS CUBA TONIGHT BUT REMAIN
WELL SE OF THE SRN FL PENINSULA. WITH THE GREATEST CONCENTRATION OF
DEEP CONVECTION CONFINED TO THE ERN SEMICIRCLE OF THIS CYCLONE IT
APPEARS THE PROBABILITY FOR TORNADOES WILL REMAIN QUITE LOW THROUGH
THE PERIOD ACROSS SRN FL.
