FEW SHOWERS ACROSS THE AREA THIS MORNING WITH WARM ADVECTION AND
UPSLOPE FLOW MAINLY OVER THE HIGHER TERRAIN. WILL MAINTAIN CHANCE

PWAT PLUME OF NEAR 1.00 INCHES BEGINNING TO SHOW UP OVER THE

COASTAL RANGE AND SHASTA REGION WHERE SOME AREAS MAY SEE 2-4 INCHES
OF RAIN. PRESSURE GRADIENT WILL LIKELY TIGHTEN SIGNIFICANTLY
ENOUGH FOR ADVISORY LEVEL WINDS LATE TUESDAY FOR VALLEY LOCATIONS.

HEAVY PRECIPITATION WILL MOVE INTO THE NORTHERN SIERRA TUESDAY NIGHT
INTO WEDNESDAY WITH STRONG FRONTAL BAND. THIS WILL BE A RELATIVELY
WARM SYSTEM WITH SNOW LEVELS RISING AS MAIN PRECIP BAND MOVES
THROUGH DUE TO MODERATE/STRONG WARM AIR ADVECTION. SO SNOW LEVELS
WILL REMAIN GENERALLY ABOVE 3500 FEET IN THE NORTHERN MOUNTAINS
AND ABOVE 5500 FEET IN THE NORTHERN SIERRA THROUGH WEDNESDAY
NIGHT. POTENTIAL FOR SEVERAL FEET OF NEW SNOW OVER THE HIGHER

HIGH...ABOVE 6000-7000 FT...BUT THEN DROP INTO THE FOOTHILLS BY
SATURDAY NIGHT/SUNDAY WHEN THE COLDER AIR MOVES IN. 700 MB TEMPS
COULD DROP AS LOW AS -15 DEGREES C BY SATURDAY NIGHT. THE COOLING
TREND IN THE EXTENDED TEMPERATURES WILL RESULT IN DAYTIME HIGHS
ABOUT 10 DEGREES BELOW NORMAL NEXT WEEKEND.   JBB
