...NO SVR TSTM AREAS FORECAST...

EARLY MORNING WATER VAPOR IMAGERY SHOWS LARGE UPPER LOW OFF THE CA
COAST...WITH STRONG UPPER JET EXTENDING ACROSS BAJA CA INTO TX/NM. 
MODEL GUIDANCE SUGGESTS THE UPPER FEATURES WILL REMAIN RELATIVELY
STATIONARY TODAY.  THIS SHOULD MAINTAIN A RISK OF SHOWERS AND
THUNDERSTORMS ACROSS MUCH OF THE SOUTHWEST UNITED STATES.

STRONG ONSHORE LOW LEVEL WINDS AND ANTECEDENT MOIST CONDITIONS ARE
AIDING IN THE MAINTENANCE OF LOWER 50S DEWPOINTS OVER THE CENTRAL
VALLEY OF CA.  OCCASIONAL BREAKS IN THE CLOUDS APPEAR POSSIBLE TODAY
OVER THIS REGION...PROVIDING MARGINAL INSTABILITY /MUCAPE VALUES
AROUND 500 J/KG/.  PRESENT INDICATIONS ARE THAT COMBINATION OF
COLDER TEMPERATURES ALOFT AND SUFFICIENT CAPE MAY POSE A RISK OF
HAIL/GUSTY WINDS IN STRONGER CELLS TODAY OVER CENTRAL CA.  ORGANIZED
SEVERE ACTIVITY APPEARS UNLIKELY AT THIS TIME.
