VALID 251200Z - 261200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE CENTRAL CALIFORNIA COAST...
..SUMMARY
THUNDERSTORMS WITH POTENTIAL TO PRODUCE MARGINALLY SEVERE WIND GUSTS
AND PERHAPS A BRIEF TORNADO, WILL BE POSSIBLE ON THURSDAY ALONG
PARTS OF THE CENTRAL CALIFORNIA COAST.
..CALIFORNIA COAST
A MID-LEVEL LOW AND AN ASSOCIATED TROUGH OVER THE EASTERN PACIFIC
WILL GRADUALLY APPROACH THE WEST COAST ON THURSDAY. AHEAD OF THE
TROUGH, A STREAM OF MOISTURE WILL FEED INTO CALIFORNIA, WHERE
SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP DURING THE DAY. AT
THE SURFACE, A FRONT IS FORECAST TO MOVE SOUTHWARD ALONG THE CENTRAL
CALIFORNIA COAST. TO THE SOUTH OF THE FRONT NEAR THE COAST, SURFACE
DEWPOINTS WILL BE IN THE 50S F. IN ADDITION, A 50 TO 60 KNOT
LOW-LEVEL JET IS FORECAST TO BE IN PROXIMITY TO THE HIGHER SURFACE
DEWPOINTS. THIS FEATURE WILL CREATE STRONG LOW-LEVEL SHEAR ALONG THE
CENTRAL CALIFORNIA COAST, WHERE SOME FORECAST SOUNDINGS HAVE CURVED
HODOGRAPHS AND 0-3 KM STORM-RELATIVE HELICITY ABOVE 250 M2/S2. THIS
COULD SUPPORT A MARGINAL SEVERE THREAT, WITH CELLS THAT ROTATE
WITHIN SHORT LINE SEGMENTS. A BRIEF TORNADO OR ISOLATED SEVERE WIND
GUST WILL BE POSSIBLE.
