DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1018 AM CST SUN NOV 23 2008
VALID 231630Z - 241200Z
...NO SVR TSTM AREAS FORECAST...
...NERN TX INTO THE MID SOUTH...
MODEST RETURN FLOW PATTERN OF GULF MOISTURE IS ALREADY UNDERWAY INTO
ERN TX...WHICH WILL INCREASE THROUGH THE PERIOD AHEAD OF FAST MOVING
SHORTWAVE TROUGH DIGGING SEWD ACROSS THE CENTRAL PLAINS. EXPANDING
AREA OF SURFACE-H85 MOISTURE AND INCREASING DEEP ASCENT WILL SUPPORT
INCREASING MOIST CONVECTION DURING THE PERIOD FROM NERN TX INTO THE
MID SOUTH. ALTHOUGH MOST OF THIS ACTIVITY WILL REMAIN QUITE SHALLOW
UNDER CAPPING EML TODAY...FORECAST SOUNDINGS INDICATE SUFFICIENT
MUCAPE WILL DEVELOP LATER THIS EVENING/OVERNIGHT FOR
THUNDERSTORMS...ESPECIALLY AROUND THE ARKLATEX. A FEW STRONGER
CORES MAY BE CAPABLE OF HAIL GIVEN THE RELATIVELY COOL TEMPERATURES
ALOFT AND EFFECTIVE SHEAR FROM 30-40 KT. HOWEVER...OVERALL SEVERE
THREAT REMAINS LOW.
