AREA FORECAST DISCUSSION
National Weather Service Eureka CA
431 AM PST Mon Nov 4 2024

.SYNOPSIS...Northerlies are forecast to diminish today and then
strengthen on Tuesday. Robust northeasterlies are expected for
southeastern interior Tuesday night and Wednesday. Dry weather
is expected to prevail through the week.

&&

.DISCUSSION...A shortwave trough will move across the Pacific
Northwest today-tonight. PWAT values increase up to 1.10 inch
along the North Coast this afternoon as moisture spills over a
stout ridge aloft offshore. Light showers or sprinkles are
possible this late afternoon and evening for the North Coast as a
decaying front approaches the west coast and shallow moist air
spreads onshore.

Upper and surface ridging will then rebuild on Tue and maintain
dry weather for the remainder the week. Prime concern heading into
Tuesday night and Wed will be the potential for strong gusty NE
winds across mostly southern Lake County. NBM probabilities for
gusts over 45 mph are less than 20% for all lower elevations
(below 1500 feet), but ramp up to 40-60% for the higher elevations
and ridges on the eastern/southern periphery of Lake County Tue
night/Wed AM. Suspect a few wind-prone ridges will gust to 50 mph
Tue night or Wed AM. There is a fire weather concern due to the
low humidity for southern Lake County which has not received very
much rain at all this fall. See fire weather section below for
more on this.

The dry offshore flow mid to late week will also make for ideal
longwave cooling where winds decouple and go calm in the interior
valleys. Assuming no low clouds or fog, freezing temperatures and
frost are probable for the interior valleys. A frost advisory or
freeze warning may be necessary for areas that have not had an
end of season freeze yet this fall.

The offshore flow pattern begins to breakdown and weaken toward
the end of the week as another trough complex begins to approach.
Most all ensemble cluster means indicate above normal 500mb heights
and a dominating ridge through Saturday, so suspect any rain is
going to be on the light side and confined to the northern most
zones. Ensemble cluster means show more variance with a potentially
deeper/colder trough toward the end of the week or early next
week. This may provide us with more rain, but the timing is vague
and details sketchy at the moment. DB

&&

.AVIATION...Areas of fog are being seen on satellite early this
morning in much of the river valleys, though all terminals remain
VFR. Some patchy fog at all terminals is not out of the question
before sunrise, but will quickly mix out after sunrise. A weak front
is moving through the area today, which will gradually lower
ceilings to MVFR at the coastal terminals, and potentially bring
rain to CEC. Conditions are forecast to improve to VFR this evening
as the front moves out. UKI will remain VFR through the day with
gusty afternoon winds possible. JB

&&

.MARINE...A large long period swell has filled in early this
morning bringing waves peaking around 16 ft at 18 seconds. Winds
remain elevated south of Cape Mendocino, also bringing steep
northerly wind waves. Winds will continue to diminish through the
day as a weak front moves through. Nearshore, seas will dip below 10
ft by Monday night. This lull will be short lived as high pressure
begins to fill back in early Tuesday, elevating winds once again.
Gale force gusts of up to 40 kts are possible in the lee of Cape
Mendocino Tuesday afternoon through early Wednesday, while gusts of
30 kts are possible in the nearshore waters. Conditions are
currently forecast to improve for the remainder of the week. JB

&&

.FIRE WEATHER...Warmer daytime temperatures and lower RH's are
forecast today through Wed, mostly for the southern interior
(Mendo and Lake). Northerlies over the exposed ridges and higher
terrain are expected to diminish today as a decaying front
approaches from the NW and provides some light showers or
sprinkles for Del Norte/Humboldt. Northerlies will strengthen on
Tuesday after shortwave trough passage into the Great Basin.
Robust northeasterlies and lower humidity are then expected for
the southeastern interior (zone 264) as a 925mb NE speed max
develops over the Sac valley Tue Eve-Wed AM. NBM mean Fosberg
index increases to 50+ along the eastern and southern fringes of
zone 264 Tue night into Wed AM in response to the drying
northeasterlies. Isolated NE wind gusts around 50 mph and single
digit RH's are certainly possible over the higher terrain of zone
264 and perhaps southern zone 277 Tue night into Wed AM. Even
though we have already transitioned to low fire weather season and
fuels are not as receptive, a headline for elevated to locally
critical conditions has been included in the planning forecast for
zone 264 which has not received very much rain yet this fall. DB

&&

.BEACH HAZARDS...A large long period NW swell has filled in early
this morning, bringing breaking waves of 20 to 24 ft. Steep,
northwest facing beaches will see the highest surf. This swell will
slowly decay through the day, with breaker waves lowering by mid-
morning below advisory levels. Despite the advisory ending, the long
period swell and light winds north of Cape Mendocino will bring a
moderate threat of sneaker waves to the Humboldt and Del Norte
coasts today. Extra care should be taken when walking along beaches
and jetties. JB

&&
