CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 041642Z - 041845Z

THUNDERSTORM INITIATION WILL BE LIKELY ACROSS THE SAN JOAQUIN VALLEY
AND SCNTRL COAST THIS AFTERNOON. THE STRONGER STORMS WILL HAVE A
POTENTIAL FOR LARGE HAIL AND A WW MAY BECOME NECESSARY.

LATEST SFC ANALYSIS CURRENTLY SHOWS A MOIST AXIS EXTENDING FROM THE
SANTA BARBARA VICINITY NWD ACROSS THE SAN JOAQUIN VALLEY WITH
DEWPOINTS IN THE MID 50S F. PARTIAL CLEARING IS EVIDENT ON VISIBLE
IMAGERY OVER THE VALLEY WHERE TEMPS HAVE WARMED TO NEAR 60 F.
ADDITIONAL DESTABILIZATION COMBINED WITH STRONG VERTICAL SHEAR WILL
BE FAVORABLE FOR ROTATING STORMS. COLD AIR ALOFT ASSOCIATED WITH AN
APPROACHING VIGOROUS UPPER-LEVEL TROUGH WILL CONTINUE TO STEEPEN
LAPSE RATES OVER CNTRL CA THIS AFTERNOON WITH THE THREAT FOR LARGE
HAIL GRADUALLY INCREASING. ISOLATED WIND DAMAGE AND/OR BRIEF
TORNADOES MAY ALSO BECOME POSSIBLE AS SFC HEATING FURTHER
DESTABILIZES THE AIR MASS
