...NO TSTM AREAS FORECAST...

...SYNOPSIS/FORECAST...
BROAD...POSITIVE TILT TROUGH WILL CONTINUE TO MOVE SLOWLY E ACROSS
THE CNTRL AND ERN U.S. THIS PERIOD AS E PACIFIC RIDGE REACHES THE W
CST/GRT BASIN.  PHASING OF SHORTWAVE IMPULSES NOW OVER THE SRN
RCKYS AND UPR MS VLY WILL RESULT IN FURTHER AMPLIFICATION OF TROUGH
OVER THE SRN PLNS.  THIS IN TURN WILL LEAD TO SFC DEVELOPMENT LATER
TODAY/TONIGHT ALONG FRONT STALLED OFF THE SC/NC CST.  THE WAVE
SHOULD ACCELERATE ENE INTO THE ATLANTIC TO A POSITION WELL OFF THE
MARYLAND CST BY 12Z MONDAY.

STRENGTHENING 925-850 MB WARM ADVECTION N OF SFC FRONT MAY YIELD
SUFFICIENT ELEVATED INSTABILITY TO ALLOW ASSOCIATED
CONVECTION/POSSIBLE THUNDER TO DEVELOP JUST OFF THE NC COAST THIS
EVENING/EARLY TONIGHT. FAST EWD MOTION OF SFC WAVE AND LIMITED
DEGREE OF MOISTURE/BUOYANCY IN ELEVATED UNSTABLE LAYER SUGGEST THAT
COVERAGE OVER LAND SHOULD REMAIN LIMITED.
