...NO SVR TSTM AREAS FORECAST...
...SOUTHEAST COAST...
GREATEST COVERAGE OF DEEP MOIST CONVECTION/THUNDERSTORMS WILL LIKELY
REMAIN OFF THE CAROLINA COAST FOR MUCH OF THE DAY AS ASCENT
TRANSLATES ENEWD OFFSHORE. WV IMAGERY INDICATES INTENSE SUBSIDENCE
EXTENDING ACROSS NRN FL...WITH MORE FOCUSED VORTICITY MOVING INTO
UPSTATE SC THIS MORNING. THIS IMPULSE WILL CONTINUE EWD AND MAY
SUSTAIN A FEW THUNDERSTORMS INTO ERN SC/FAR SERN NC THROUGH THE
AFTERNOON AS SURFACE LOW ADVANCES EWD OFF THE GA/SC COAST...BUT
OVERALL COVERAGE INLAND WILL LIKELY REMAIN LIMITED.
DEEP MOIST CONVECTION SHOULD ALSO PERSIST ACROSS SRN FL THROUGH THE
MID TO LATE AFTERNOON IN ADVANCE OF SURFACE COLD FRONT SAGGING SEWD
INTO THE CENTRAL PENINSULA. THIS REGION WILL REMAIN WITHIN
SUBSIDENT FLOW AND WEAKENING SURFACE CONVERGENCE WHICH SHOULD LIMIT
OVERALL THUNDERSTORM POTENTIAL.
...PAC NW COAST...
ANOTHER COMPACT IMPULSE EVIDENT ON WV IMAGERY DIVING SSEWD ALONG THE
BC COAST SHOULD MOVE INTO THE WA/ORE COAST LATER TODAY/TONIGHT.
THIS MAY SUPPORT A FEW LOW-TOPPED THUNDERSTORMS ALONG AND WEST OF
