AREA FORECAST DISCUSSION
National Weather Service Eureka CA
245 PM PST Thu Dec 29 2022

.SYNOPSIS...Rain will spread across Northwest California tonight,
and become heavy Friday through Saturday morning resulting in an
increased potential for localized flooding. In addition, strong
gusty winds will occur across exposed ridges from Southern
Humboldt County south across Lake and Mendocino Counties during
Friday afternoon and evening. After Saturday, an active wet
pattern is forecast to continue through the middle of next week.

&&

.DISCUSSION...A zonally oriented plume of ascent and moisture was
located over the NERN PAC and coastal portions of OR and NWRN CA.
Precipitation, mainly in the form of rain, will spread across the
EKA CWA tonight as moisture/ascent continue to increase with the
passage of a midlevel wave. A stronger wave will then amplify
Friday, and approach the West Coast early Saturday morning. A
surface wave will deepen along an east-west baroclinic zone as the
upper features moves east, and westerly moisture flux will
subsequently increase with IVT values approaching 750 kg/m/s.
Rainfall will become moderate to heavy as a result, with rates
peaking during Friday afternoon and evening. In addition, 40-60 kt
westerly flow at 925 mb will promote advisory levels gusts across
exposed ridges from Southern Humboldt County south across Lake
and Mendocino Counties during Friday afternoon and evening.
Furthermore, freezing levels are forecast to rise to around
7000-9000 feet MSL during Friday, and then fall to around 5000
feet MSL Saturday afternoon. However, heavy precipitation will be
ending by that point...thus impactful snowfall appears unlikely
across the interior mountains through the next 48 hours.

The previously mentioned upper trough is then forecast to pass
east of the region going into Saturday afternoon. Rainfall will
diminish in intensity as a result. Model guidance shows midlevel
shortwave ridging occurring Sunday, which will support a day of
dry weather. Another rain producing upper wave then passes east
across the area Monday, with a potentially stronger storm system
impacting the region during the middle of next week.

&&

.AVIATION...Intervals of rainy weather disturbances brought light
occasional moderate impacts to TAF sites and other regional
airfields today. These systems are basically associated with an
atmosphere river (AR), and will continue across the region over
{at least} the next 24 to 48 hours. The progression of storms will
be the catalyst for consequential flight hazards through all of
Friday which includes: mostly light to moderate (occasionally
heavy) precipitation, MVFR/IFR Cig/VIS, strong gusty
winds...especially at the coast and possible low level wind shear
(LLWS). /TA

&&

.MARINE...An active weather pattern will yield periods of strong
gusty winds and steep hazardous seas during the next seven days.
Gale force southerlies will occur this evening across the northern
outer waters, followed by another round of west-southwest winds
gusting to around 30 kt over the southern waters during Friday
afternoon. Gusty north winds will then prevail across all waters
during the weekend, with additional rounds of strong south winds
during early to middle portions of next week.

&&

.HYDROLOGY...An atmospheric river will impact Northwest California
Friday into Saturday morning. Rainfall totals will range from 4
to 7 inches across west-southwest facing terrain, while valleys
and coastal plains experience totals from 2 to 4 inches. Heavy
rainfall will increase the potential for urban and small stream
flooding. In addition, rapid rises are expected on rivers, with
flood stage expected to be reached on the Eel River at Fernbridge,
and the Russian River near Hopland during Saturday.
