AREA FORECAST DISCUSSION
National Weather Service Eureka CA
301 PM PDT Mon Apr 18 2022

.SYNOPSIS...Gusty winds will continue through late this afternoon
across exposed ridges and coastal areas. Widespread rainfall will
continue to spread across the area into the evening, with showers
persisting into Tuesday. Another round of gusty south winds and
widespread beneficial rain will occur on Wednesday, with
additional showers and locally heavy mountain snow occurring on
Thursday. Drier weather and warmer temperatures are expected by
the weekend.

&&

.DISCUSSION...Southerly winds continue to be quite gusty across
the N half of the area, and the Wind Advisory was extended until 5
PM. A narrow band of heavy showers along the approaching front is
making its way inland along the North Coast. There appeared to be
several bowing segments in the line of convection, and a Marine
Weather Statement and a Special Weather Statement for adjacent
land areas were issued for gusty, shifting winds and the potential
for some small hail. Snow totals in portions of the Trinity Alps
will 6 to 8 inches in isolated backwoods locations, but little to
no accumulation is expected in the more populated or traveled
areas. Locally heavy rainfall rates will occur along the frontal
band, but only localized minor flooding in poor drainage areas is
expected.

A low pressure trough off the Pacific NW coast will lift NE and
fill tonight. Widespread rain and high elevation snow will
continue to spread across the area this afternoon and evening,
with showers lingering into Tuesday.

After a brief break in the weather late Tuesday, another trough will
dig into the area. This system will be a bit colder and wetter, with
the potential for advisory-level mountain snows, particularly near
Scott Mountain Pass. Rain from this system and the lingering showers
afterward will range from nearly 3 inches across inland the Del
Norte interior terrain to around three quarters of an inch across
southern Lake and Mendocino counties. More gusty winds are
expected with this system. Winter weather and wind products will
likely be issued by the midnight shift or Tuesday's day shift.

Drier and warmer weather is anticipated for the weekend as a high
pressure ridge builds over the area. /SEC

&&

.AVIATION...Ahead of an approaching cold front, an influx of
mostly VFR clouds moved over the North Coast this morning.
Prefrontal accelerated southerly winds frequently reached over 40
MPH impacting the DEl Norte Coast...and especially CEC.
Additionally, a possible flight hazard of mainly directional LLWS
may have been somewhat burdensome until the afternoon frontal
passage. Across interior Mendocino, a brief period of MVFR Cigs
developed and was reported at UKI.

The cold front moved over CEC about 1343 LST as reported by a
special ASOS report. At that time Rain/Shower intensities increased
and VIS rapidly decreased with Cig dropping into MVFR.  Along the
front, winds rapidly increased and possibly cause a significant
flight hazard. The front will continue to move SSE through the rest
of the afternoon and evening. Conditions will taper this evening
before a post frontal trough swings across the region early tuesday.
/TA

&&

.MARINE...Gales force southerly winds will continue across the
northern waters through early this evening. A strong line of heavy
showers is moving into nearshore this afternoon, and accompanied for
small hail and gusty winds. The Crescent City and Eel River Buoys
reported wind gusts up to 42 kts ahead of this line of showers along
of the cold front. Have to extend the Gale Warning for the northern
waters through 5PM. Meanwhile, high-end advisory level winds are
over the southern waters, though some isolated gale force wind gusts
have developed around Cape Mendocino. Winds weaken across all zones
to just below advisory levels this evening and overnight and persist
through Tuesday. Another front looks to approach Wednesday, possibly
ramping southerlies back up to Gale Force once again. Winds then
significantly weaken in the back half of this week.

Seas will remain very steep and hazardous across the northern waters
through tonight. Buoys north of Cape Mendocino are already reporting
combined seas up to 12 foot. A Hazardous Seas Warning is in place
for the northern waters zone. Seas for the next couple of days will
be primarily composed of locally generated southerlies and fresh
west swell. Current guidance is indicating the locally southerly
wind field associated with the next front on Wednesday will stretch
a little farther to our south, which should help increase the fetch
and the local wave generation response...so currently expecting
larger southerly seas with this next system even though local wind
speeds look similar to today's front. Additionally, the fetch in the
cold sector of midweek's system out in the NEPAC is forecasted to
elongate then follow building seas from the Aleutians during
Tuesday...possibly bringing another solid west swell. Current
numbers looking like a peak of 15 ft at 16 seconds from 280 deg
Thurs night. Another low looks to speed across this section of the
NEPAC later this week, possibly sending us another WNW swell this
weekend.
