DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1249 AM CDT TUE OCT 14 2008
VALID 151200Z - 161200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
BROAD/FLAT TROUGH IS FORECAST ACROSS MUCH OF THE CONUS THIS
PERIOD...WITH WEAK RIDGES OVER BOTH THE SOUTHEAST AND THE ERN
PACIFIC/FAR SWRN CONUS.
AT THE SURFACE...A WEAK LOW IS FORECAST TO MOVE ACROSS THE MIDWEST
ALONG A LINGERING BAROCLINIC ZONE. IN ITS WAKE...THE FRONT WILL
MOVE SLOWLY SEWD...AND SHOULD EXTEND FROM PA SWWD INTO SERN TX BY
THE END OF THE PERIOD.
...MID MS/LOWER AND MID OH VALLEYS...
A WEAKENING MID-LEVEL SHORT-WAVE TROUGH -- EMBEDDED WITHIN THE
LARGER-SCALE CYCLONIC FLOW -- IS EXPECTED TO MOVE ENEWD FROM THE
CENTRAL PLAINS TO THE LOWER GREAT LAKES REGION THROUGH THE PERIOD.
AS THE ASSOCIATED SURFACE WAVE MOVES EWD ACROSS THE MIDWEST...MEAGER
BUT SUFFICIENT AFTERNOON DESTABILIZATION COMBINED WITH LOW-LEVEL UVV
INVOF THE LOW MAY SUPPORT THE DEVELOPMENT OF A FEW SUSTAINED
STORMS/STORM CLUSTERS. THOUGH THE OVERALL LACK OF INSTABILITY
ANTICIPATED SHOULD ACT TO HINDER STORM INTENSITY...MODERATE WLY FLOW
ALOFT MAY SUPPORT WEAK STORM ORGANIZATION -- AND POSSIBLY A VERY LOW
PROBABILITY THREAT FOR MARGINAL HAIL OR GUSTY WINDS. ANY THREAT
SHOULD QUICKLY WANE BY EVENING AS ANY EXISTING INSTABILITY
DIMINISHES.
