DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1113 AM CDT TUE OCT 09 2007
VALID 091630Z - 101200Z
..NO SVR TSTM AREAS FORECAST...
UPPER LOW CURRENTLY OVER WESTERN ONTARIO WILL DRIFT SLOWLY
SOUTHEASTWARD ACROSS THE GREAT LAKES REGION DURING THE FORECAST
PERIOD. THIS WILL HELP TO FORCE A SURFACE COLD FRONT EASTWARD
ACROSS THE APPALACHIANS BY WEDNESDAY MORNING. AHEAD OF THE
FRONT...SKIES ARE MOSTLY CLEAR FROM THE CAROLINAS INTO PA AND
CENTRAL NY. THIS WILL HELP TO DESTABILIZE THIS REGION AND SHOULD
RESULT IN SCATTERED AFTERNOON THUNDERSTORMS. MORNING RAOBS AND
FORECAST SOUNDINGS SHOW WEAK MID LEVEL LAPSE RATES AND MARGINAL CAPE
VALUES LIMITING UPDRAFT INTENSITY THROUGHOUT THE AREA. HOWEVER...
FAVORABLE VERTICAL SHEAR PROFILES AND PRESENCE OF MULTIPLE SURFACE
BOUNDARIES MAY ALLOW AN ISOLATED STORM OR TWO TO BECOME
STRONG/SEVERE THIS AFTERNOON FROM CENTRAL NY/PA INTO PARTS OF
MD/DE/NJ. GUSTY/DAMAGING WINDS WOULD BE THE MAIN THREAT.
