.KEY MESSAGES...

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

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

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

.DISCUSSION...As an upper level low approaches the PACNW, gusty
winds and the chance for rain increases. Winds are likely to
diminish a bit by Sunday but remain breezy, without the 20-25kt
gusts we have been witnessing over the past few afternoons and
evenings. With the winds easing Sunday, temperatures could warm
slightly.

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/EYS

.AVIATION...Stout northerly winds have mixed down this afternoon
as VFR conditions return to all area terminals. KCEC is likely to
see diminishing winds by 5-6z tonight. Northerlies return by
Sunday afternoon at KCEC but models indicate that sustained winds
will be 10kts at the most. KACV has a bit less exposure than KCEC
and has had inconsistent periods of gusts. KACV will continue with
sustained winds up to 15kts through the early evening and
intermittent periods of 15-25kt gusts. Winds ease tonight by
07-08z with a northeasterly bearing around 2-3kts. LLWS does not
appear to be an issue as winds seem to be mixing down to the
surface at KUKI except for the intermittent periods of gusts which
could affect approach or take off unexpectedly. Flight conditions
are prevailing VFR at KUKI with gusts around 18-22kts, easing by
03z. /EYS


&&

.MARINE...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 through 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
