NWS STORM PREDICTION CENTER NORMAN OK
0632 PM CST FRI FEB 26 2010
VALID 270100Z - 271200Z
...NO SVR TSTM AREAS FORECAST...
...LA COAST...
MID LEVEL SHORTWAVE TROUGH CONTINUES TO DIG SEWD TOWARD THE LOWER MS
VALLEY REGION. THIS HAS PREVENTED ANY MEANINGFUL BOUNDARY LAYER
MOISTURE TO SPREAD INLAND ALONG THE LA COAST...WITH THE PRIMARY
FRONTAL ZONE LOCATED JUST OFFSHORE. LARGE SCALE ASCENT ATOP COOLER
AIRMASS WILL CONTRIBUTE TO AN EXPANSIVE PRECIP SHIELD DURING THE
OVERNIGHT HOURS...HOWEVER DEEP CONVECTION WILL GRADUALLY EASE
OFFSHORE AND LIGHTNING POTENTIAL IS DECREASING ACROSS THIS REGION.
...CA...
LEAD SHORTWAVE TROUGH IS ROTATING NEWD ACROSS NRN CA WITH
SUBSTANTIAL MID LEVEL SUBSIDENCE/DRYING SPREADING INTO REGION AHEAD
OF MAIN UPPER LOW. DEEP CONVECTION WILL BE LIMITED IN THE WAKE OF
THIS LEAD SHORTWAVE UNTIL LATER TONIGHT WHEN STRONG FRONT BEGINS TO
SURGE INLAND. AT THAT TIME ISOLATED THUNDERSTORMS WILL LIKELY BE
NOTED ALONG/BEHIND PRIMARY WIND SHIFT.
