DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0146 AM CST WED FEB 10 2010

VALID 121200Z - 131200Z

...SYNOPSIS...
AN UPPER TROUGH WILL CONTINUE CROSSING THE CENTRAL -- AND LATER THE
ERN -- U.S. WITH TIME THIS PERIOD...WHILE EXPANDING AS REINFORCING
FEATURES ROTATE SWD/SEWD OUT OF CANADA INTO THE CENTRAL U.S. ON THE
WRN FRINGE OF THE CYCLONIC FLOW FIELD.

COOL/CONTINENTAL AIRMASS WILL REMAIN ACROSS THE MAJORITY OF THE
CONUS...WITH THE PRIMARY SURFACE CYCLONE ASSOCIATED WITH THE ERN
U.S. UPPER TROUGH PROGGED TO MOVE EWD ACROSS THE GULF OF MEXICO.

WHILE THIS LOW MAY MOVE ACROSS FAR SRN FL -- POSSIBLY ALLOWING A
LIMITED INCREASE IN CONVECTIVE POTENTIAL ACROSS S FL AND THE
KEYS...ATTM IT APPEARS THAT INSTABILITY/SHEAR COMBINATION WILL BE
INSUFFICIENT TO SUPPORT APPRECIABLE SEVERE POTENTIAL...AND THUS WILL
NOT INTRODUCE EVEN LOW SEVERE PROBABILITY THIS FORECAST.
