TEMPERATURES ACROSS NORTHWEST CALIFORNIA TODAY. A STORM SYSTEM WILL
MOVE ACROSS THE REGION BRINGING A CHANCE OF LIGHT PRECIPITATION
WEDNESDAY. COOLER TEMPERATURES WILL MOVE IN BEHIND THE STORM
AND GRADUALLY MODERATE INTO THE WEEKEND.
&&

.DISCUSSION...SAT IMAGERY SHOWS LIMITED STRATUS ALONG PORTIONS OF
THE COAST AND INLAND VALLEYS WITH MID/HIGH CLOUDS MOVG ACROSS CWA
EARLY THIS MORNING. UPPER LEVEL RIDGE OFFSHORE WILL WEAKEN TODAY
AS UPPER LOW NEAR 35N/130W SLOWLY DRIFTS N. A COLD FRONT WILL PUSH
ACROSS NW CA WED AS A LONG WAVE TROUGH DEEPENS. MODELS CONTINUE
TRENDING DRIER WITH THIS FRONT SO CONTINUE TO EXPECT MINIMAL QPF
AMOUNTS WITH UP TO 1/4 INCH IN DEL NORTE COUNTY. A COLDER AIRMASS
WILL ADVECT INTO THE REGION BEHIND THE FRONT LOWERING SNOW LEVELS
TO 1-2KFT...BUT MAJORITY OF PRECIP WILL BE OVER WITH ONLY ISOLD
SHOWERS EXPECTED INTO THU MORNING. UPPER RIDGE OFFSHORE NOSES
OVER THE PAC NW THU AND TROUGH DIGS INTO THE GULF OF CA. BY THIS
WEEKEND...NW CA WILL BE SITUATED BETWEEN THE OFFSHORE RIDGE AND
INLAND TROUGH. WITH THIS UPPER LEVEL PATTERN...MINOR IMPULSES
TRAVERSING ACROSS THE REGION COULD PRODUCE SOME SHOWERS...SO KEPT
SOME MENTIONABLE...BUT BELOW CLIMO...POPS ACROSS NRN CWA THROUGH
THE EXTENDED.
&&

.AVIATION...SHALLOW GROUND BASED MIST MAY PRODUCE REDUCED VSBYS AT
CEC AND ACV EARLY THIS MORNING. HAZY CONDITIONS MAY ALSO DEVELOP
LATER TODAY AS LIGHT SEA BREEZES DEVELOP. STRATUS WAS WELL OFFSHORE
THIS MORNING AND DOES NOT POSE MUCH OF A THREAT FOR LOW CIGS TODAY.
THE THERMAL TROUGH OVER COASTAL WATERS THIS MORNING WILL SHIFT
INLAND THIS AFTERNOON AND TONIGHT. BOUNDARY LAYER SHOULD MOISTEN
UP AS NORTHERLY FLOW RETURNS. THIS WILL RESULT IN BETTER CHANCES
OF LOW CLOUD GROWTH TONIGHT INTO WED MORNING.

WED. WINDS AND SEAS WILL RAMP UP SUBSTANTIALLY WED NIGHT AND THU AS
A LOW PRES TROUGH DROPS DOWN FROM THE NORTH. I HOISTED GALE WATCHES

WINDS WILL BE WED NIGHT AND THU. WITH N WINDS OF 40 KT EXPECTED IN
PZZ475...SEAS SHOULD HIT 20 FT ON THU. A NEW LONG PERIOD SWELL FROM
