...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
A PROGRESSIVE UPPER PATTERN WILL CONTINUE...WITH A POTENT SHORT WAVE
TROUGH IMPACTING THE PACIFIC COAST...LEADING TO CYCLOGENESIS OVER
CNTRL CA AND THE GREAT BASIN. DOWNSTREAM UPPER RIDGING WILL AMPLIFY
OVER THE CNTRL/SRN ROCKIES...WHILE A COMPACT SHORT WAVE TROUGH OVER
THE LOWER MS VALLEY QUICKLY EJECTS EWD...REACHING THE CAROLINA COAST
BY LATE PERIOD.

...FL PENINSULA...
A COMPACT SHORT WAVE TROUGH WILL GLANCE THE AREA...POSSIBLY
BOLSTERING ASCENT ALONG A SLOW SWD PROGRESSING COLD FRONT OVER CNTRL
FL. MODEL FORECASTS SUGGEST THE SUBTROPICAL MOISTURE PLUME THAT HAS
CONTRIBUTED TO RECENT THICK CLOUD COVER ACROSS THE GULF INTO THE MID
ATLANTIC WILL PERSIST...LEADING TO QUESTIONABLE INSTABILITY ACROSS
THE FL PENINSULA /PARTICULARLY N FL/. VEERING BUT WEAK LOW LEVEL
WIND PROFILES ALONG THE E COAST MAY SUPPORT A BRIEF STRONG TO SEVERE
STORM GIVEN A STRONGER UPDRAFT. HOWEVER...MARGINAL MID-LEVEL LAPSE
RATES AND LOW-LEVEL WIND SHEAR/FLOW WILL LIKELY HINDER A MORE
WIDESPREAD SEVERE THREAT.
