DISCUSSION
CONSISTENTLY STRONG NORTHERLY WINDS HAVE DIMINISHED
EARLY THIS WEEK FOR NORTHWEST CALIFORNIA AS THE PRESSURE GRADIENT
EASES. WINDS WILL DIE DOWN OVER NIGHT AND THEN BECOME GENERALLY
BREEZY IN THE AFTERNOONS THROUGHOUT THIS WEEK. OVERNIGHT LOWS WILL
BE ON THE CHILLY SIDE AGAIN TONIGHT, BUT WILL BEGIN MODERATING THIS
WEEK WITH BUILDING HIGH PRESSURE. SOME AREAS OF LOCALIZED FROST WILL
BE POSSIBLE IN THE HAYFORK AND LARABEE VALLEY THIS MORNING.
CONDITIONS WILL REMAIN VERY DRY WITH WARMING TEMPERATURES THROUGH
THE WEEK. HIGHS WILL MOST LIKELY TOP OUT AROUND 90 FOR THE INTERIOR
ON THURSDAY. THIS WILL CONSTITUTE ONLY A MINOR HEATRISK FOR THIS
TIME OF YEAR. HOTTER TEMPERATURES WILL HELP REFORM A MARINE
INVERSION AND WILL INCREASE CHANCES FOR COASTAL STRATUS AND FOG THIS
WEEK
AVIATION
NORTHERLY WINDS HAVE, FOR THE MOST PART, MOVED
OFFSHORE, EXCEPT AT POINT SAINT GEORGE AND CAPE MENDOCINO WHERE
WINDS WILL REMAIN ELEVATED OVERNIGHT. GUSTS UP TO 20 KNOTS CAN BE
EXPECTED AROUND KCEC VERY EARLY THIS MORNING BEFORE DYING DOWN
BEFORE SUNRISE. OTHER TERMINALS IN NORTHWEST CALIFORNIA WILL
EXPERIENCE GENERALLY CALM WINDS BEFORE SUNRISE. THIS PATTERN OF
DIMINISHED WINDS OVERNIGHT AND HIGHER WINDS DURING THE AFTERNOON
WILL CONTINUE THROUGH THE WORK WEEK. WIDESPREAD VFR CONDITIONS ARE
ANTICIPATED WITH A SLIGHT PROBABILITY OF COASTAL STRATUS FORMING
AROUND HUMBOLDT BAY EARLY THIS MORNING. THROUGHOUT THIS WEEK,
COASTAL STRATUS IS LIKELY TO FORM EACH NIGHT AND BURN OFF AFTER
SUNRISE AS HIGH PRESSURE CONTINUES FOR THE REGION. /JLW
MARINE
THE PRESSURE GRADIENT RELAXES SLIGHTLY AND THE STRONGEST
WINDS MOVE FARTHER OFF THE COAST AS THE HIGH PRESSURE BUILDS IN.
HOWEVER, A LARGE AREA OF GALE FORCE GUSTS AROUND 34-45 KTS ARE
EXPECTED ACROSS ALL ZONES, WITH THE STRONGEST WINDS DOWNWIND OF
CAPE MENDOCINO. STEEP TO VERY STEEP, HAZARDOUS SEAS WILL CONTINUE
WITH THE ELEVATED WINDS. CONDITIONS WILL REMAIN HAZARDOUS ACROSS
THE WATERS FOR MUCH OF THE WORK WEEK WITH STRONG TO GALE FORCE
NORTHERLY GUSTS AND STEEP TO VERY STEEP SEAS. GALE FORCE WINDS AND
VERY STEEP SEAS ARE FORECAST TO PERSISTS ACROSS THE OUTER WATERS
THROUGH FRIDAY. /ZVS
