DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1208 PM CDT TUE OCT 25 2011
VALID 261200Z - 271200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
WEAK CONVECTION IS EXPECTED TO DEVELOP IN ASSOCIATION WITH A FRONTAL
ZONE FROM PORTIONS OF THE OH VALLEY...SWWD INTO THE SRN PLAINS AND
SRN ROCKIES. THIS ACTIVITY WILL BE EMBEDDED WITHIN SEVERAL LARGER
ZONES OF PRECIPITATION...INDUCED PRIMARILY WITHIN A POST FRONTAL
ENVIRONMENT AS POOR WARM SECTOR INSTABILITY/INHIBITION WILL PROVE
DETRIMENTAL FOR FREE CONVECTION AHEAD OF THE WIND SHIFT. THE ONLY
EXCEPTION WILL BE ACROSS THE OH VALLEY WHERE LOW LEVEL CONVERGENCE
MAY PROVE ADEQUATE FOR NEAR SFC-BASED ACTIVITY AS TEMPERATURES WARM
INTO THE LOWER 70S. EVEN SO CONVECTION WILL BE QUICKLY UNDERCUT AND
ASCENT ATOP FRONTAL ZONE SHOULD BE THE PRIMARY FORCING FOR UPDRAFTS.
ACROSS SOUTH FL...RICHER MOISTURE WILL LIFT NWD ACROSS THE FL
STRAITS WITHIN DEEPER ESELY FLOW WELL EAST OF HURRICANE RINA.
ALTHOUGH POOR LAPSE RATES ARE EXPECTED TO PERSIST ACROSS THIS REGION
IT APPEARS HIGH PWAT VALUES MAY SUPPORT ISOLATED TSTMS.
