...SYNOPSIS...
EWD PROGRESSION OF ERN PACIFIC TROUGH WILL OCCUR THROUGH THE DAY ONE
PERIOD WITH SEVERAL WEAKER PERTURBATIONS MOVING THROUGH THE MEAN
PATTERN ONTO THE W COAST. IN THE LOW-LEVELS...IT APPEARS THAT
PRIMARY FRONTAL SYSTEM WILL REMAIN OVER THE FAR ERN PACIFIC THROUGH
WEDNESDAY MORNING.

...CNTRL VALLEY OF CA...
GRADUAL MOISTENING OF ENVIRONMENT WILL OCCUR THROUGH THE PERIOD WITH
SHOWERY PRECIPITATION BECOMING PROGRESSIVELY MORE WIDESPREAD LATER
THIS AFTERNOON INTO EVENING. CONSIDERABLE CLOUD COVER AND POOR LAPSE
RATES /AOB MOIST ADIABATIC/ WILL TEND TO LIMIT AIR MASS
DESTABILIZATION. HOWEVER...LATEST MODEL GUIDANCE DOES SUGGEST THAT
DIABATIC HEATING MAY CONTRIBUTE TO POCKETS OF WEAK INSTABILITY THIS
AFTERNOON WITH MUCAPES APPROACHING 100-200 J/KG. DESPITE RATHER WEAK
LARGE-SCALE FORCING...LOCALIZED OROGRAPHIC EFFECTS AND THE MARGINAL
INSTABILITY SHOULD BE SUFFICIENT TO SUPPORT A FEW TSTMS EMBEDDED
WITHIN LARGER PRECIPITATION SHIELD.
