VALID 241200Z - 251200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ALONG PARTS OF
THE CALIFORNIA COAST AND INLAND IN THE SAN JOAQUIN VALLEY...
..SUMMARY
THUNDERSTORMS WITH MARGINALLY SEVERE WIND GUSTS, HAIL AND
POTENTIALLY A BRIEF TORNADO WILL BE POSSIBLE FROM WEDNESDAY INTO
WEDNESDAY NIGHT ALONG PARTS OF THE CALIFORNIA COAST, AND INLAND
ACROSS THE SAN JOUQUIN VALLEY.
..CALIFORNIA
A RIDGE ALOFT WILL MOVE EASTWARD ACROSS THE CENTRAL U.S. ON
WEDNESDAY, AS A MID-LEVEL TROUGH MOVES EASTWARD ACROSS THE EASTERN
PACIFIC. AHEAD OF THIS LARGE-SCALE FEATURE, A SUBTLE SHORTWAVE
TROUGH WILL APPROACH THE CALIFORNIA COAST WEDNESDAY AFTERNOON. AS
HEIGHTS GRADUALLY FALL, LARGE-SCALE ASCENT AND MID-LEVEL MOISTURE
WILL OVERSPREAD MOST OF CALIFORNIA DURING THE DAY. THUNDERSTORM
DEVELOPMENT WILL BE POSSIBLE ALONG THE CENTRAL AND SOUTHERN
CALIFORNIA COAST, AND INLAND ACROSS THE SAN JOAQUIN VALLEY. THE
GREATEST CHANCE FOR SEVERE STORMS WILL BE AS THE LEFT EXIT REGION OF
A 90 TO 100 KNOT MID-LEVEL JET MOVES ACROSS THE SAN JOAQUIN VALLEY
DURING THE MID TO LATE AFTERNOON. NEAR THIS FEATURE, VERY STRONG
DEEP-LAYER SHEAR WILL EXIST AND MUCAPE IS EXPECTED TO PEAK IN THE
500 TO 750 J/KG RANGE. THIS SHOULD BE ENOUGH FOR A FEW
SEMI-ORGANIZED STORMS WITH A THREAT FOR HAIL AND MARGINALLY SEVERE
GUSTS. A BRIEF TORNADO WILL ALSO BE POSSIBLE. AN ISOLATED SEVERE
THREAT IS EXPECTED TO CONTINUE INTO THE OVERNIGHT PERIOD, AND MAY
SHIFT SOUTHWARD ALONG THE COAST INTO SOUTHERN CALIFORNIA, AS A
SECOND MINOR IMPULSE APPROACHES AND MOVES INLAND.
