NWS STORM PREDICTION CENTER NORMAN OK
1210 PM CDT WED SEP 02 2009
VALID 031200Z - 041200Z
...NO SVR TSTM AREAS FORECAST...
...SOUTHERN PLAINS...
UPPER LOW OVER CENTRAL SD WILL DIG SSEWD INTO SERN KS/NERN OK
THURSDAY...GRADUALLY WEAKENING AS IT BECOMES ABSORBED WITHIN BROADER
TROUGH OVER THE MS/OH VALLEY. THIS FEATURE WILL ENHANCE MID LEVEL
NNWLY FLOW ACROSS THE PLAINS WHILE SERVING TO DRIVE EFFECTIVE SFC
FRONT TO A POSITION NEAR THE RED RIVER OF OK/TX BY LATE AFTERNOON.
ALTHOUGH CONVERGENCE WILL BE SOMEWHAT LIMITED ALONG LEADING WIND
SHIFT...STRONG SFC HEATING ACROSS THE SRN PLAINS WILL STEEPEN LOW
LEVEL LAPSE RATES SUFFICIENTLY FOR SFC PARCELS TO APPROACH THEIR
CONVECTIVE TEMPERATURES. SCATTERED THUNDERSTORMS SHOULD DEVELOP
WITHIN SHEAR ENVIRONMENT SEEMINGLY FAVORABLE FOR A FEW ORGANIZED
ROBUST MULTI-CELL CLUSTERS. GUSTY WINDS OR PERHAPS SOME HAIL COULD
ACCOMPANY THIS ACTIVITY.
...ELSEWHERE...
SCATTERED-NUMEROUS THUNDERSTORMS WILL DEVELOP ACROSS MUCH OF THE SRN
ROCKIES INTO NRN MEXICO WHILE THE FL PENINSULA WILL ONCE AGAIN BE
CONVECTIVE-ACTIVE AHEAD OF WEAK MID LEVEL TROUGH.
THERMODYNAMIC/SHEAR PROFILES IN THESE AREAS DO NOT APPEAR
PARTICULARLY FAVORABLE FOR SUSTAINING ORGANIZED SEVERE
THUNDERSTORMS.
