AREA FORECAST DISCUSSION
National Weather Service Eureka CA
240 PM PDT Fri Jul 19 2024

.SYNOPSIS...Quiet, dry, weather continues today, with temperatures
at or above normal.  There is a slight chance of thunderstorms in
the northern part of the area.


&&

.DISCUSSION...Dry, seasonable weather continues across the area
today. Coastal stratus has remained stubborn along the Humboldt
coast early this afternoon. Some scattering may occur this
afternoon, but it will make a comeback this evening. Interior
temperatures this afternoon have warmed into the 90s and low 100s.
Temperatures will stay warm this weekend, though cloud cover is
expected to moderate temperatures in areas. A shortwave offshore
will move toward the coast Saturday evening, driving that cloud
cover and upper-level moisture. Additional moisture will allow for
the marine layer to deepen, potentially allowing for stratus to stay
in most, if not the entire day, along the coast. Inland, daytime
heating and upper-level moisture could allow for dry thunderstorms,
primarily around the Siskiyou county border, though chances remain
around 10 percent. While small, the low moving closer to shore will
allow for a chance of convection Saturday night into early Sunday
morning.

Dry and warm conditions are expected into the early week. SREF does
hint at some convective potential Sunday and Monday afternoon in NE
Trinity county, but upper-level moisture is even less available
than Saturday. Temperatures will continue to warm up, with
temperatures well into the 100s in most interior valleys by Monday
into early next week. JB

.AVIATION...Typical stratus overcast conditions continued along the Del Norte
and Humboldt Coasts today...and briefly penetrated into the Eel
River Valleys this morning.  The marine layer has been stubborn
enough to linger along the Del Norte/Humboldt "immediate" coastlines
into mid-afternoon; weather impacts at the terminals were mixed IFR
SCT-BKN...specifically at ACV. A little tightening of the coastal
pressure gradient could produce a few afternoon gusts, but overall
light winds. Inland areas may experience some layers from wildlife
smoke (definitely depicted on Vis Sat Pics), otherwise SKC. The
marine layer will once again be present at the coast Saturday
morning. /TAA


&&

.MARINE...Gale watch for Monday afternoon into Tuesday as north
winds behind a passing cold front could be quite strong. NBM 4.2
probabilities indicate that a solid half of the outer waters stand
a 50 percent chance of max sustained north winds greater than
35-40 KT range. Increasing winds and steepening seas are still
expected heading into tonight and Saturday, with the current small
craft advisory to include all southern waters by this afternoon
and reaching into the northern outer waters by Saturday. /MH
