DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1238 AM CDT TUE AUG 07 2012

VALID 071200Z - 081200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
LITTLE OVERALL CHANGE IN THE LARGE-SCALE UPPER FLOW PATTERN IS
FORECAST THIS PERIOD...WITH A RIDGE REMAINING OVER THE W AND
TROUGHING IN THE E. SHORTER-WAVELENGTH TROUGHS MOVING SEWD ACROSS
THE PLAINS AND ALSO ESEWD ACROSS THE SERN U.S. WILL BE ASSOCIATED
WITH AREAS OF DIURNALLY DRIVEN CONVECTION.

AT THE SURFACE...A GENERALLY NONDESCRIPT PATTERN IS FORECAST. A
WEAK FRONT IS PROGGED TO CROSS THE UPPER GREAT LAKES/UPPER MIDWEST
REGION...WHILE WEAKER LOWS/CONVERGENCE ZONES PREVAIL ACROSS THE
PLAINS STATES AND OVER THE SERN U.S. IN CONJUNCTION WITH
AFOREMENTIONED WEAK UPPER TROUGHING.

...THE PLAINS...
WEAK LARGE-SCALE ASCENT WITHIN THE BROAD NWLY FLOW FIELD ALOFT
ACROSS THE PLAINS REGION IS FORECAST TO AID IN THE DEVELOPMENT OF
ISOLATED SHOWERS AND THUNDERSTORMS...AS DIURNAL HEATING SUPPORTS
AIRMASS DESTABILIZATION. LIMITED FLOW ALOFT SUGGESTS LITTLE
POTENTIAL FOR WELL-ORGANIZED CONVECTION...BUT A FEW STRONGER CELLS
MAY BE CAPABLE OF PRODUCING GUSTY WINDS AND/OR MARGINAL HAIL THROUGH
MID EVENING.

...THE SOUTHEAST...
WIDESPREAD SHOWERS AND THUNDERSTORMS ARE AGAIN FORECAST ACROSS THE
SOUTHEAST U.S. TODAY...AS ASCENT ASSOCIATED WITH A WEAK MID-LEVEL
TROUGH DRIFTING SLOWLY SEWD INTERACTS WITH A VERY MOIST/MODESTLY
UNSTABLE AIRMASS. WITH FLOW ALOFT FORECAST TO REMAIN WEAK ACROSS
THE REGION...LITTLE POTENTIAL EXISTS FOR ORGANIZED STORMS.
STILL...AN ISOLATED STRONGER GUST OR TWO MAY OCCUR WITH
STRONGER/PULSE-TYPE CONVECTION ACROSS THE REGION.
