DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0758 PM CDT SAT AUG 23 2008
VALID 240100Z - 241200Z
...THERE IS A SLGT RISK OF SVR TSTMS FROM PARTS OF SRN AL...SW GA
AND THE NE FL PANHANDLE...
...SRN AL...THROUGH SWRN GA AND PORTION OF FL PANHANDLE...
EARLY THIS EVENING THE CENTER OF TROPICAL STORM FAY WAS LOCATED NEAR
THE BORDER OF THE WRN FL PANHANDLE AND SRN AL NEAR SAMSON AL. FAY IS
FORECAST BY THE NHC TO CONTINUE SLOWLY WWD THE REMAINDER OF TONIGHT.
STRONGER LOW LEVEL WINDS AND LARGER HODOGRAPHS REMAIN NORTH AND EAST
OF THE CENTER FROM S CNTRL AL SEWD THROUGH SW GA AND THE NE FL
PANHANDLE. THE MORE DISCRETE STORMS ASSOCIATED WITH OUTER RAINBANDS
REMAIN EAST OF THE CENTER FROM THE NE GULF SPREADING INTO THE NE FL
PANHANDLE AND SW GA. STORMS FARTHER NORTH ARE EMBEDDED WITHIN A MORE
WIDESPREAD AREA OF STRATIFORM RAIN. SOME OVERALL DECREASE IN
INTENSITIES MAY OCCUR OVERNIGHT WITH ONSET OF NOCTURNAL COOLING.
HOWEVER...LARGE HODOGRAPHS AND MOIST LOW LEVEL ENVIRONMENT WILL
CONTINUE TO SUPPORT A THREAT OF LOW LEVEL MESOCYCLONES AND ISOLATED
TORNADOES.
...W CNTRL KS THROUGH SRN NEB...
A QUASISTATIONARY FRONT EXTENDS FROM THE LOWER MS VALLEY WWD INTO
EXTREME SRN KS THEN NWWD THROUGH W CNTRL KS. THE ATMOSPHERE REMAINS
MODERATELY UNSTABLE IN VICINITY OF THIS BOUNDARY WITH MLCAPE AROUND
1500 J/KG. LIMITED FRONTAL CONVERGENCE SUPPORTED ONLY ISOLATED
THUNDERSTORM DEVELOPMENT DURING THE DAY. A MODEST SLY LOW LEVEL JET
IS FORECAST TONIGHT ACROSS WRN KS CONTRIBUTING TO ISENTROPIC LIFT
AND POTENTIAL FOR ADDITIONAL STORMS TO DEVELOP FROM NW KS THROUGH
SRN NEB. INSTABILITY AND MID LEVEL LAPSE RATES MAY BE SUFFICIENT FOR
A THREAT OF MARGINALLY SEVERE HAIL WITH THE STRONGER STORMS.
...SE CO...
SCATTERED STORMS THAT DEVELOPED OVER THE HIGHER TERRAIN WILL REMAIN
CAPABLE OF PRODUCING ISOLATED STRONG WIND GUSTS AND HAIL AS THEY
SPREAD SEWD INTO THE HIGH PLAINS OF SE CO. ACTIVITY SHOULD BEGIN AN
OVERALL WEAKENING TREND BY MID EVENING AS THE BOUNDARY LAYER BEGINS
TO COOL.
