DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0723 AM CDT SUN OCT 28 2007
VALID 281300Z - 291200Z
..NO SVR TSTM AREAS FORECAST...
THE BROAD...COLD UPPER TROUGH OVER THE GREAT LAKES REGION IS
FORECAST TO TRACK EASTWARD ACROSS NEW ENGLAND TODAY...ALLOWING UPPER
RIDGE TO BEGIN TO BUILD NORTHWARD ACROSS THE ROCKIES AND PLAINS
STATES. MEANWHILE...EXPANSIVE SURFACE HIGH PRESSURE AREA WILL
HINDER RETURN OF LOW LEVEL MOISTURE AND PRECLUDE THUNDERSTORM
DEVELOPMENT OVER MOST AREAS. THE PRIMARY EXCEPTION WILL BE OVER THE
FL PENINSULA WHERE LOW LEVEL EASTERLIES WILL MAINTAIN A MOIST AND
MARGINALLY UNSTABLE AIR MASS. ALL MODEL GUIDANCE SUGGESTS A THREAT
FOR SCATTERED SHOWERS AND THUNDERSTORMS TRAVERSING EAST TO WEST
ACROSS THE PENINSULA. RELATIVELY WEAK VERTICAL SHEAR AND LIMITED
DAYTIME HEATING SHOULD GREATLY LIMIT THUNDERSTORM INTENSITY TODAY.
