.SYNOPSIS...Light to moderate showers along with gusty winds over
the higher terrain. Showers will tapper off late this afternoon,
with lingering showers through tonight. Followed by drier and
warmer conditions by mid week.

.DISCUSSION...Northwest California is currently under the influence
of a weak late season storm system involving cyclogenesis and an
associated occluded front pushing onshore. This is bringing rain
showers, mountain snow and gusty west-southwest winds. Radar
doppler depicts light to moderate showers moving northeastward
across the area, with periods of steady rain observed in Del Norte
and Humboldt counties overnight. The low pressure will moves over
the area today and keep driving southeastward through Tuesday.
This will continue to support unsettled weather and cold
temperatures through today/tonight. Isolated thunderstorms are
possible (15-25% chance) this afternoon over the higher terrain
north of Cape Mendocino, especially in Trinity County. Showers
activity are anticipated to tapper off late this afternoon, with
lingering showers through tonight.

 On Tuesday, a shortwave ridge will begin to builds in the wake
of the trough filtering a slightly drier airmass. However, some
isolated light showers are possible to developed inland Tuesday
afternoon due to a lingering low level moisture and diurnal
heating. A warming trend is expected to start on Tuesday, with
inland highs warm up into the mid 60`s to mid 70`s. Enhancing
onshore flow will remain the coastal areas in the mid to upper
50`s. Areas of valley fog are expected to develop Tuesday night
into Wednesday.

All ensembles continue showing a high confidence for a weak
ridging persisting across the area through late in the week.
Expect warmer and drier weather conditions across Northwest
California for the remainder of the work week. /ZVS

.AVIATION...Rain has turned showery during the overnight as
expected, with ceilings largely remaining IFR or MVFR. Winds remain
breezy through the night at CEC, and should continue easing this
morning. Showers taper off this afternoon with overall conditions
improving to VFR/MVFR range. /MH



&&

.MARINE...Northern waters are in Small Craft Advisory this morning,
with the southern waters reaching SC.Y by this afternoon. Combined 6
to 9 foot seas will set in today and build to 10- 12 feet by late
tonight into Tuesday early morning. Steep waves will keep small
craft conditions going through at least Wednesday evening for
southern waters. A short break from small craft conditions is
forecast for northern waters by early Tuesday morning as steep waves
return, with fresh to strong northerlies and steep seas begin to
build again tonight into Tuesday, peaking in the afternoon. NBM has
around a 30% chance of Gale Force gusts in the lee of Cape Mendocino
Tuesday afternoon. /MH
