AREA FORECAST DISCUSSION ...CORRECTED
National Weather Service Eureka CA
332 PM PDT Tue Mar 14 2023

.SYNOPSIS...Rain will diminish this evening and then end overnight.
Gusty northerly winds are expected this evening. Dry and cooler
weather is expected Wednesday through Thursday, followed by
additional periods of light rain amounts Friday and during the
weekend.

&&

.DISCUSSION...A compact circulation center has been moving across
the area this afternoon. Blustery northerly winds have been
occurring north of Cape Mendocino while strong southeasterlies have
been occurring across Mendocino and Lake counties. Winds will shift
to the northwest everywhere later this afternoon into early this
evening and will be borderline for a wind advisory. Gusts to 25 to
35 mph are most probable, however a few windier locations (coastal
headlands and ridges) will have higher gusts to 40-50mph.
Winds should abate overnight as the low heads eastward and
dissipates.

Upper level ridging will build on Wednesday and maintain dry weather
through Thursday. Relatively colder low temperatures are forecast
for the next couple of nights with less cloud cover and lighter
winds. Moist and snow covered grounds will likely result in
extensive fog and low clouds for many of the interior valleys for
the next couple of nights. Temperatures may not be as cold as the
National Blend of Models indicate.

Additional periods of relatively light precipitation is forecast
Friday through Sunday with potentially stronger and wetter storms
with relatively high snow levels (above 3500-4000 feet) early to
mid next week. Signal for another atmospheric river storm is weak
at the moment, 50-60% chance, with the longer duration of IVT's of
250kg/m/s or more south of 38N. This will need to be watched for
a northward shift and increasing IVT's or water vapor flux from
the subtropics.

&&

.AVIATION...Low pressure, southwest of the Mendocino Coast, continued
to bring plenty of precipitation to the region. Mostly VFR/MVFR
ceilings were reported at coastal stations with brief IFR visibilities
in heavier rain. Another weather band with showers and gusty
northerlies expected to move through in the mid to late afternoon.
Flight hazard impacts have been more significant for aviation
operations in the SE and S areas...including UKI. Flight weather
over Mendocino and Lake Counties also experienced strong southerly
wind with gusts potentially reaching 30 knots this afternoon.
Wind should become NW to N at UKI in the late afternoon.
Regionally, conditions will start to improve tonight as the low
pressure exits the region. /TA

&&

.MARINE...Gale force northerly winds and large steep seas are
expected through tonight after a compact low moves inland.
Northerly conditions will remain elevated on Wednesday and then
settle down on Thursday as a weaker frontal system approaches.
A couple of weaker fronts will transition across the area Friday
through Saturday, with low potential for advisory level conditions.

&&

.HYDROLOGY...Periods of moderate to heavy rainfall this afternoon
will continue to promote localized urban and small stream flooding.
The water will be slow to recede in some areas tonight. The Eel
river at Fernbridge has been just above flood stage of 20 feet
today. With more moderate to heavy rain this afternoon, the stage
is forecast to rise to 23 feet late tonight. Ensemble stage
forecast has about a 33% chance of the river to reach 24 feet or
more. The Russian river at Hopland is also forecast to reach flood
stage of 15 feet by this afternoon and evening. The Mad River at
Arcata has been above Monitor stage. Meanwhile, the Van Duzen
river at Bridgeville is forecast to rise to Monitor stage again
this afternoon and evening. Probabilities for flood stage
exceedance are about 19& for the Van Duzen at Bridgeville and 14%
for the Mad at Arcata. The upshot is all rivers will recede during
the day on Wednesday and no hydrologically significant
precipitation is forecast through the weekend. GEFS and ENS
indicate another possibility for IVT's around 250kg/m/s early to
mid next week. Probabilities are around 50-60% north of 37-40N
with durations are 24-36 hours. Another atmospheric river storm
will certainly be possible, however confidence on the details
(timing, location) are quite low at the moment.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...

     Wind Advisory until 5 PM PDT this afternoon for CAZ109>115.
