DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1136 PM CST THU FEB 07 2008
VALID 081200Z - 091200Z
..NO SVR TSTM AREAS FORECAST...
..SYNOPSIS...
PROGRESSIVE MID/UPPER LEVEL FLOW PATTERN WILL CONTINUE ACROSS THE
CONUS TODAY. A LEAD SHORT WAVE TROUGH WILL MOVE EWD AWAY FROM THE
MID ATLANTIC REGION...WHILE THE NEXT UPSTREAM TROUGH TRACKS FROM THE
CENTRAL HIGH PLAINS TO THE CENTRAL APPALACHIANS BY 12Z SATURDAY.
MEANWHILE...WEAKER MID LEVEL IMPULSES WILL TRACK FROM MEXICO THROUGH
THE GULF OF MEXICO AND ACROSS CENTRAL FL. IN THE LOW LEVELS...A
SURFACE FRONT EXTENDING ACROSS CENTRAL FL AT 12Z TODAY IS FORECAST
TO MOVE SLOWLY SWD BEFORE WASHING OUT ACROSS SRN FL TONIGHT.
..SRN FL...
ALTHOUGH LAPSE RATES WILL BE WEAK...SURFACE DEWPOINTS S OF THE FRONT
IN THE 60S COMBINED WITH HEATING SHOULD SUPPORT WEAK INSTABILITY AND
THE POTENTIAL FOR TSTMS TO DEVELOP AS THE FRONT MOVES SWD TODAY.
TSTMS SHOULD ALSO OCCUR OVER SERN FL ALONG THE EAST COAST SEA BREEZE
BOUNDARY DURING THE LATE AFTERNOON. MODELS SUGGEST A WEAK SURFACE
WAVE TRACKING EWD ALONG THE SURFACE FRONT AND INTERACTING WITH THE
SEA BREEZE WILL ENHANCE LOW LEVEL CONVERGENCE/UPWARD VERTICAL MOTION
FOR TSTMS. WEAK INSTABILITY/LAPSE RATES AND LACK OF APPRECIABLE
SHEAR/FORCING SUGGEST LITTLE POTENTIAL FOR VIGOROUS STORMS AND
ATTENDANT SEVERE WEATHER THREAT TODAY.
