DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0748 PM CDT MON SEP 15 2008
VALID 160100Z - 161200Z
...NO SVR TSTM AREAS FORECAST...
...SERN CONUS...
EARLY EVENING SURFACE ANALYSIS SHOWED A BOUNDARY EXTENDING FROM SRN
NC WSWWD THROUGH CENTRAL SC TO EAST CENTRAL GA...AND THEN SSWWD TO
THE ERN FL PANHANDLE. MODELS SUGGEST THIS BOUNDARY SHOULD CONTINUE
TO SHIFT SLOWLY SEWD OVERNIGHT AND SHOULD EXTEND FROM THE SRN NC/SC
COAST TO NWRN FL BY 12Z TUESDAY. OBJECTIVE ANALYSES INDICATED
WEAKENING INSTABILITY ACROSS THE WARM SECTOR GIVEN THE LOSS OF DAY
TIME HEATING. THIS TREND IS EXPECTED TO RESULT IN FURTHER DECREASE
IN DEVELOPMENT OF ANY NEW TSTM ACTIVITY ALONG THE SURFACE FRONT AND
SEA BREEZE BOUNDARIES. THERE IS SOME POTENTIAL FOR TSTMS TO FORM
WITHIN A ZONE OF INCREASING WAA/MOIST UPSLOPE FLOW ACROSS THE WRN
CAROLINAS LATER TONIGHT AS NELY-ELY LOW LEVEL WINDS DEVELOP ON THE
NORTH SIDE OF THE SURFACE BOUNDARY.
...SRN ROCKIES...
TSTMS THAT FORMED THIS AFTERNOON OVER THE HIGHER TERRAIN OF SRN CO/
NRN NM INTO ADJACENT PARTS OF THE OK PANHANDLE AND NERN AZ WILL
CONTINUE TO DIMINISH IN AREAL EXTENT AS THE LOSS OF DAY TIME HEATING
STABILIZES THE BOUNDARY LAYER.
