SWODY1
SPC AC 091951

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0151 PM CST SUN NOV 09 2008

VALID 092000Z - 101200Z

...NO SVR TSTM AREAS FORECAST...

...SWRN OK INTO ADJACENT N TX AND THE TX PANHANDLE...
INCREASING WARM ADVECTION IS FORECAST DURING THE SECOND HALF OF THE
PERIOD ACROSS THE SRN PLAINS AHEAD OF ADVANCING SHORT-WAVE TROUGH.
AS A RESULT...THE COMBINATION OF PERSISTENT LOW-LEVEL
MOISTENING/DESTABILIZATION AND INCREASING ASCENT SHOULD SUPPORT THE
DEVELOPMENT/EXPANSION OF ELEVATED CONVECTION OVER THIS REGION
OVERNIGHT.

WHILE A GENERAL LACK OF INSTABILITY SHOULD PRECLUDE APPRECIABLE
SEVERE POTENTIAL IN MOST AREAS...A FEW STRONGER CELLS CAPABLE OF
PRODUCING MARGINALLY-SEVERE HAIL MAY EVOLVE ACROSS PARTS OF THE TX
PANHANDLE/NWRN TX AND ADJACENT SWRN OK LATE IN THE PERIOD.
OTHERWISE...SEVERE WEATHER IS NOT ANTICIPATED.

..GOSS.. 11/09/2008
