What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Eureka, CA wrote its last area forecast discussion before this small craft advisory went out at Mar 27, 12:08 AM PDT, 5 hours 50 minutes earlier.
Area forecast discussion, Mar 27, 12:08 AM PDT, 5 hours 50 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1208 AM PDT Fri Mar 27 2026
.SYNOPSIS...Breezy to strong offshore winds are expected through
dawn for ridgetops. Dry conditions with above normal high temperatures
are expected for the interior through the weekend. Potential for significant
precipitation still on track for next week.
&&
.DISCUSSION...Dry conditions expected through dawn under offshore
flow. Adiabatic warming from the large scale subsidence is resulting
in a wide range of overnight low temperatures, varying greatly depending
on elevation. With a warmer airmass building and winds generally restricted
to the ridgelines, wind sheltered valleys and coastal areas will stand
the best chance for frost and freezing/subfreezing temperatures. Some
wind sheltered valleys will dip down into the low 30's, while breezier
wind prone areas exposed to adiabatic warming may not even dip below
60F (mostly in/above the thermal belts for ridges). Frost advisories
have been issued for the interior valleys of Mendocino County as well
as coastal areas of Del Norte and Humboldt again. Interior portions
of Humboldt and Del Norte are 6 days from the start of the growing
season (Apr 1) while Trinity County is 21 days away (Apr 15). That
is why frost/freeze products have not been issued for these zones.
This dry and stable weather is expected into the weekend. Daytime
temps will generally be above normal high temperatures with areas
of minor heat risk mostly the interior as a broad, flat, upper-
lvl ridge dominates. The warmest locations will continue to be in
Lake, Trinity and interior Mendocino Counties where max temps are
projected to peak into the upper 70s to mid 80s Fri-Sun. This is
10- 20F above late March averages. Overnight low temps will remain
seasonably chilly with valley sites (especially for Trinity Co.)
continuing to to cool into the lower to mid 30's as stable,
colder, denser air pools into the valleys each night. As this cool
air drains each night, a thermal belt will continue to develop
around midslopes keeping higher elevations warmer and dryer
through the night. No huge changes are anticipated this weekend
except for an increase in coastal stratus and perhaps a ramp up in
onshore or NW winds.
The National Blend of Models (NBM) and NOAA CPC is still supporting
the trend of much cooler and wetter next week. Our long stretch of
above normal interior warmth will finally end next week with highs
trending near (or even just under!) early April normals by mid week.
With this incoming cooler air, there is increasing confidence in at
least a few days of precipitation next week. How much precipitation
and the exact timing remains uncertain, yet the window looks to be
wettest for Tuesday and Wednesday as the highest WPC/NBM 6-hourly
rates appear to arrive on Wednesday (+/- 12-24hrs). The NBM 3-day/72hr
totals from 5 AM Mon-5AM Thu range from over 2-5" inches on the higher
end (top 75th percentile) to 0.5-1.00" on the lower end (bottom 25th
percentile). Most of the precip is concentrated in the usual wet spots
of Del Norte, SW Humboldt and NW Mendocino, while southern Lake and
southern Mendocino may end up with much less.
As for snowfall, this incoming cold weather pattern will lower the
snow levels a few times for this upcoming storm next week. Model data
shows an initial lowering of snow levels down to 4500- 5000ft by
Wednesday morning before a secondary lowering to 3000-3500ft by
Thursday morning. Its important to remember that snowlevels are
very dependent on where the low pressure actually arrives and
that this amount of detail is subject to change by next week as a
clearer forecast becomes available, yet for right now this is what
we know. Finally, The NBM still has 6-hr and 12-hr thunderstorm
chances less than 15%. However, if the cold core aloft dips far
enough south, we could definitely see some low top thunderstorms
and small hail. Stay tuned for updates and more details. DS
&&
.AVIATION...(27/06Z TAFs)..Prevailing VFR conditions at all
terminals during the next 24-36 hr, with high-level clouds streaming
across the area. Northerly winds continue to decouple from the
surface, becoming light ENE overnight. After 27/17Z, winds will
shift to the NW and increase for the coastal terminals. Meanwhile,
very light and variable winds will persist at UKI. /ZVS
&&
.MARINE...Northerly winds are beginning to diminish across the
coastal waters. Near-gale to gale northerly winds are expected to
continue across the outer waters through early Friday, leaving very
steep seas over the northern outer waters through late Friday
morning. Small craft conditions will most definitely persist through
Friday night.
Winds will decrease over the weekend as an area of low pressure
begins to develop off the California coast. This will significantly
reduce the pressure gradient across the waters. A weak front is
forecast to move through the waters on Monday allowing the northerly
winds to increase slightly in its wake. The next chance for strong
winds will be mid next week as a more potent frontal system moves
into the region. /ZVS&RPA
