NWS STORM PREDICTION CENTER NORMAN OK
1027 AM CST MON FEB 27 2006

VALID 271630Z - 281200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
12Z SOUNDINGS ALONG THE CA COAST INDICATED WEAK ELEVATED INSTABILITY
LOCATED WITHIN A BROAD PLUME OF SUB-TROPICAL MOISTURE STREAMING
INLAND IN ADVANCE OF THE PACIFIC TROUGH...WITH THE SRN EXTENT
CURRENTLY CENTERED NEAR 31N 137W PER WATER VAPOR IMAGERY.  THIS
INSTABILITY WILL CONTINUE TO SUPPORT A FEW THUNDERSTORMS
TODAY...MAINLY ALONG AND OFFSHORE OF THE IMMEDIATE CA COAST...SINCE
A DRIER LOW-LEVEL AIR MASS INLAND SHOULD PRECLUDE SUFFICIENT
DESTABILIZATION FOR STORMS.

THE PACIFIC TROUGH AND ASSOCIATED SURFACE FRONT ARE EXPECTED TO MOVE
INLAND TONIGHT...WITH INSTABILITY GRADUALLY BECOMING ROOTED NEAR THE
GROUND LATE IN THE FORECAST PERIOD WEST OF THE MAIN BAROCLINIC ZONE
AS STEEPER LAPSE RATES SPREAD INLAND.  GIVEN 35-45 KT SWLY LOW-LEVEL
WINDS...A FEW STRONGER WIND GUSTS MAY REACH THE SURFACE WITH SHALLOW
CONVECTION ALONG THE FRONT OVERNIGHT...BUT OVERALL THREAT IS
EXPECTED TO REMAIN TOO LOW TO INTRODUCE SEVERE PROBABILITIES.
