...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
PROGRESSIVE UPPER FLOW WILL EXTEND FROM THE WEST COAST TO THE SCNTRL
U.S. ON THURSDAY AS A COMPACT SHORT WAVE TROUGH...NOW CROSSING THE
SRN PLAINS...MOVES ACROSS THE LOWER MS VALLEY AND TOWARD THE SERN
STATES. UPPER RIDGE SPREADING FROM THE INTERIOR WEST ACROSS THE
ROCKIES WILL MAINTAIN SUBSIDENCE OVER THESE AREAS WHILE A COMPLEX
ERN PACIFIC TROUGH DEVELOPS SLOWLY EWD TOWARD THE WEST COAST THROUGH
LATE IN THE PERIOD. IN THE NORTHEAST AND GREAT LAKES...A COMPONENT
OF THE LARGE POLAR VORTEX THAT HAS DOMINATED ERN CANADA FOR THE PAST
WEEK WILL ROTATE SWD AND SEWD ACROSS THE GREAT LAKES AND EVOLVE INTO
A CLOSED LOW ACROSS THE UPPER OH VALLEY AREA THROUGH EARLY IN THE
WEEKEND.

...SRN FL...
LARGE SCALE FORCING FOR ASCENT ASSOCIATED WITH APPROACHING LOWER MS
VALLEY UPPER TROUGH IS EXPECTED TO RESULT IN WEAK FRONTAL WAVE
CYCLONE DEVELOPMENT ALONG RESIDUAL SYNOPTIC FRONT RETURNING NWD OVER
SRN FL. DESPITE RECENT CONTINENTAL POLAR AIR MASS INTRUSION ACROSS
THE ATLANTIC WATERS AND MUCH OF NRN AND CNTRL FL...65-70F SURFACE
DEWPOINTS WILL BE TRANSPORTED NWD/EWD WITH THE FRONT AND SURFACE
WAVE THROUGH THE AFTERNOON. DIFFERENTIAL HEATING BETWEEN
INCREASINGLY CLOUDY CONDITIONS ACROSS NRN AND CNTRL FL...AND PARTLY
CLOUDY SKIES OVER SRN FL WILL FURTHER ENHANCE THE LOW LEVEL BOUNDARY
AS WEAK TO MODEST WARM SECTOR DESTABILIZATION LEADS TO SCATTERED
TSTM DEVELOPMENT.

A SAMPLE OF FORECAST SOUNDINGS FROM THE NAM/ETA INDICATED A WEAK
SUBSIDENCE INVERSION MAY EXIST ABOVE 700MB WHICH WOULD TEND TO LIMIT
STORM UPDRAFTS. HOWEVER...MESOSCALE FORCING AND POTENTIAL FOR
RELATIVELY STRONG SHEAR AND STORM INFLOW COULD EVOLVE NEAR THE FRONT
OR LOW MOVING ACROSS SOUTHEAST COASTAL AREAS. THIS COULD RESULT IN A
FEW STRONGER UPDRAFTS AND PERHAPS BRIEF LOW LEVEL STORM ROTATION
WITH ONE OR TWO CELLS DURING THE AFTERNOON. TORNADO/WATERSPOUT
PROBABILITIES CURRENTLY APPEAR QUITE LOW BUT POTENTIAL WILL BE NEED
TO BE MONITORED LATER TODAY AS ADDITIONAL SOUNDINGS AND ANALYSES
BECOME AVAILABLE.
