AREA FORECAST DISCUSSION
National Weather Service Eureka CA
301 PM PDT Mon Apr 14 2025
.SYNOPSIS...Warm and dry weather continues today across the
interior. A cooling trend is expected Tuesday through Thursday.
There is a slight chance for thunderstorms over the interior
mountains Tuesday and Wednesday.
&&
.DISCUSSION...Warm and dry conditions continue today across most of
the area, with coastal stratus being the only clouds in sight.
Stratus has kept temperatures moderated at the coast, with highs
expected to remain (if not already achieved) in the high 50s or low
60s. Inland, today is expected to be the warmest day with mid to
high 80s possible in the warmest valleys. An upper level low moves
into southern California over the coming days. This will bring us
upper-level moisture and scattered cloud cover. High temperatures
are forecast to trend downward slightly by Wednesday, with most
valleys seeing 70s to low 80s. Increased instability could cause a
few showers or thunderstorms to pop up in the interior mountains.
Eastern Trinity, Mendocino, and Northeastern Lake have the greatest
chances to see thunderstorms (15-20% chance). Uncertainty is
still high as the position of the low will determine the amount of
moisture we receive. If we end up drier, thunderstorms are
unlikely to form. Some model solutions Wednesday are showing
increased moisture, with a slightly higher thunderstorm chance.
Others are showing a cold front moving past by Wednesday
afternoon, which will bring cool, dry air and lower thunder
chances. Coastal northerly winds are forecast to be breezy
Wednesday, especially in Del Norte. NBM probabilities for a gust
greater than 30 mph are around 80% in Del Norte.
A weaker system moves down from the north on Thursday, but any
precipitation is likely east of the area. Breezy northerly winds of
20-30 mph are possible, along with near average temperatures. High
pressure build late week into the weekend, with 80s once again
possible for the interior. Ensemble members are hinting at another
system late this weekend. NBM probabilities for any precipitation
are less than 10% at this time. JB
&&
.AVIATION...VFR conditions prevailed for all terminals this afternoon
beneath dry northerly flow and high pressure. A persistent eddy of
marine stratus is still circulating around the central Humboldt
coast, but has so far remained confined to the immediate shoreline
without affecting ACV. NW winds 5 to 10 knots will diminish along
the coast this evening - HREF is indicating that coastal stratus
will develop under a nearshore southerly wind reversal by 8 to 10Z,
especially at ACV. There is a high probability (50 to 75% chance)
for IFR ceilings <1000 ft and viz <2SM by 14Z Tuesday, increasing
for CEC through the morning hours. Widespread coastal stratus may be
reinforced by a weak frontal boundary descending from the NW Tuesday
morning.
&&
.MARINE...Gentle to moderate northerly winds continue across the
waters today beneath high pressure. Northerlies are expected to
increase through Tuesday as a cutoff low off the SoCal coast
amplifies the coastal pressure gradient. Fresh to strong breezes in
the northern outer waters will quickly increase to gales by
Wednesday morning. Sustained gales with gusts exceeding 40 knots are
possible by Wednesday afternoon, mostly confined to the northern and
outer waters. These strong gusts will likely migrate into northern
nearshore waters with diurnal heating. Steep and hazardous wind
waves reaching 12 to 15 will develop as a result of these winds,
persisting through Thursday. Conditions in the southern inner waters
will be significantly dampened expecting areas nearshore and
downwind of Cape Mendocino.
