&&

.DISCUSSION...
A WEAKENING COLD FRONT WILL PUSH ONTO THE NORTH COAST THIS MORNING
GENERATING SOME LIGHT RAIN AT THE COAST WITH PERHAPS ISOLATED SHOWERS
FARTHER INLAND. HIGHEST CHANCES/AMOUNTS LOOK TO BE THIS MORNING AND
IN DEL NORTE COUNTY WITH THE DECAYING SURFACE BOUNDARY. A SECONDARY
SPIKE IN SCATTERED PRECIP ACTIVITY WILL PROBABLY OCCUR THIS
AFTERNOON AS A +100KT JET TAKES AIM ON THE NORTHERN MOST PORTION
OF THE FORECAST AREA. MOISTURE APPEARS SHALLOW AND DYNAMICS WEAK

MORNING. HOWEVER THERE PROBABLY WONT BE MUCH IF ANY SNOW
ACCUMULATIONS AS THE MARGINAL CONVECTION FIGHTS THE SUBSIDING AIR
MASS. MAIN AFFECT WILL BE COOLER TEMPERATURES INLAND...AS MUCH AS
10-25 DEGREES BELOW NORMAL WED AND THU. COASTAL AREAS SHOULD COOL
DOWN AS WELL...BUT THE CHANGE WONT BE AS DRAMA-TIC. TEMPERATURES
OF 32F OR LESS ARE LIKELY IN THE INTERIOR EARLY WED MORNING AND
AGAIN EARLY THU MORNING. UPGRADED THE FREEZE WATCH IN TRINITY
COUNTY TO A FREEZE WARNING. CONFIDENCE IS NOT HIGH FOR INTERIOR
MENDO AS THE COVERAGE AND DURATION APPEARS TO BE LESS. MENDO
COUNTY STANDS A BETTER CHANCE OF SEEING CLEAR SKIES FOR MAXIMUM
LONG-WAVE COOLING. THE WATCH MAY NEED TO BE UPGRADED TO A FREEZE
WARNING OR DOWNGRADED TO A FROST ADVISORY. PORTIONS OF HUMBOLDT
AND DEL NORTE COUNTY MAY SEE PATCHES OF FROST OR SPOTTY FREEZING

THROUGH THE MORNING. LOW MVFR TO IFR CIGS WILL PREVAIL ALONG THE
COAST N OF CAPE MENDO TODAY. PERIODS OF -RA WILL RESULT IN PERIODS
OF IFR/MVFR VSBYS. PRECIP AND CLOUDS WILL EXPAND INLAND WITH IMC
CONDITIONS EXPECTED N OF CAPE MENDO THROUGH THE AFTERNOON. SLY WINDS
WILL INCREASE AS THE FRONT APPROACHES THEN SHIFT TO THE NW AS THE

ALTHOUGH PERIODS OF MVFR CIGS ARE POSSIBLE ALONG THE COAST THROUGH
THE AFTERNOON.

&&

.MARINE...MESO MODELS CONTINUE TO SHOW MARGINAL GALES CLIPPING THE
NW WATERS THIS MORNING AS A DYNAMIC LOW PASSES TO THE N. THIS IS
SUPPORTED BY 05Z ASCAT PASS SHOWING GALES NEAR 42N/130W. WINDS AND
SEAS WILL RISE RAPIDLY THIS MORNING AS THE FRONT ASSOCIATED WITH THE
