National Weather Service Eureka CA
1214 AM PDT Sat Jun 6 2026

expected through the weekend. Breezy winds are expected today and
Sunday, with low relative humidities in the interior bringing

.KEY MESSAGES...

- Near normal temperatures and dry weather expected through the
  weekend.

-  Widespread breezy to gusty winds this afternoon and Sunday, with
low RH values promoting locally elevated fire conditions across the
interior.

- Rain likely Monday, with the highest amounts north of Cape
Mendocino.

.DISCUSSION...The southern tip of a weak front moving into Oregon
and Washington is bringing a few high clouds to the area. This
will also bring breezy winds and cooler temperatures this
afternoon. Gusts of 20 to 30 mph are possible, with locally higher
winds expected on exposed ridges and coastal headlands. Winds
will lower slightly and temperatures may warm slightly on Sunday.

Wet weather is expected to return to portions of the area on Monday.
Models are slowly coming into better agreement that Humboldt and Del
Norte counties will see some rain on Monday. NBM is showing around a
80-90% chance for wetting rain (>0.1") in Humboldt and Del Norte
Counties, with chances falling off in areas south and east. There is
now even a 60% chance for over an inch of rain in Del Norte. Areas
of southern Mendocino and Lake may only see a few sprinkles. There
are also some discrepancies in timing on the models where some have
rain beginning Monday morning and some more into the afternoon and
evening. This will become clearer over the next day or so.

Tuesday there may be some lingering clouds and showers around with
fairly cool temperatures. Highs may only be in the upper 60s to low
70s. Tuesday night into Wednesday morning will likely be the
chilliest morning with some of the coldest spots dropping into the
upper 30s. At this point frost is not expected, but it is not out of
the question for cold spots like Ruth and Hayfork.

Warming temperatures are expected to start on Wednesday and will
likely continue to to warm through the end of the week and into the
weekend. Highs in the 90s are expected to be widespread by Friday
across the inland areas. Warming is expected to continue into the
weekend. MKK/JB

.AVIATION...(6Z TAFs)...A weak front moving through the area is
disrupting the marine layer, bringing VFR conditions and only a
few high clouds. Still, some stray MVFR to VFR stratus is
possible before sunrise. Any ceilings will likely scatter by the
afternoon. Low level wind shear is possible across the area early
this morning as winds remain strong at 1500-2000 ft AGL while
surface winds ease. Breezy northerly winds are expected at the
terminals by late morning and through the afternoon. JB


&&

.MARINE...Winds diminish slightly early this morning, but gale force
winds are likely to return for the southern waters this afternoon.
In addition to the wind driven waves there is a 11 second swell
around 5 feet. This is expected to slowly diminish over the next
several days.

Sunday night and Monday, a front is expected to approach the area.
The winds are expected to quickly diminish Sunday night and become
southerly on Monday. South winds may be moderate in the northern
waters, with gusts up to 25 kts. There is still some uncertainty on
the placement of the low, and some models do show stronger, near
gale force winds. Behind the front on Tuesday winds are expected to
become northerly again. At this point it looks like they will
increase gradually on Tuesday, but most models agree they will
exceed 20 to 25 kt by Tuesday afternoon. Also on Tuesday a post
frontal swell looks like it may build to around 7 feet at 9 seconds,
but again confidence is low on this. Stronger northerly winds are
expected to continue for the rest of the week. MKK/JB


&&

.FIRE WEATHER...Gusty west-northwest winds are expected in interior
areas this afternoon and Sunday. Afternoon gusts could approach 20
to 30 mph, even in lower elevations. Temperatures will cool on
today with most interior areas staying in the 70s. This will keep
the RH slightly higher, but still the eastern portions of the
area (Eastern Trinity, Eastern Mendocino, and Lake Counties) could
see min RHs in the mid 20s to 30s. Locally higher winds in Lake
County, where fine fuels are relatively dry, could bring locally
critical fire weather conditions. Sunday, winds are expected to be
lighter, but still breezy with gusts up to 20 to 25 mph. RHs are
likely to be lower with many interior areas seeing RHs in the
teens as temperatures warm back into the low 80s. A trough Monday
is expected to bring cooler temperatures and higher RH to the
area. There is also the potential for a wetting rain.
Probabilities of a wetting rain range from over 90 percent in Del
Norte to around 10 percent in southern Lake county. JB/MKK
