DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0630 PM CST MON FEB 18 2008
VALID 190100Z - 191200Z
...NO SVR TSTM AREAS FORECAST...
WATER VAPOR IMAGERY SHOWS A LARGE UPPER-LEVEL TROUGH OVER THE MS
VALLEY AND GREAT LAKES REGION. AT THE SFC...A COLD FRONT IS LOCATED
OFF THE COAST OF THE CAROLINAS AND EXTENDS SWWD ACROSS THE CNTRL FL
PENINSULA. THE LATEST OBJECTIVE ANALYSIS SHOWS WEAK INSTABILITY IN
PLACE ACROSS CNTRL FL WITH ABOUT 20 TO 30 KT OF LOW-LEVEL FLOW. THIS
ALONG WITH WEAK CONVERGENCE ALONG THE BOUNDARY SHOULD BE ENOUGH TO
CONTINUE A POTENTIAL FOR ISOLATED THUNDERSTORMS EARLY THIS EVENING.
HOWEVER...ANY MARGINAL SEVERE THREAT APPEARS TO HAVE ENDED ACROSS
THE FL PENINSULA. ELSEWHERE...THUNDERSTORM DEVELOPMENT IS NOT
EXPECTED TONIGHT ACROSS THE CONUS.
