AREA FORECAST DISCUSSION
National Weather Service Eureka CA
356 PM PDT Sun May 19 2019

.SYNOPSIS...As low pressure departs to our south, showers will
quickly taper off, and drier weather conditions can be expected
tonight and much of Monday. Another storm system will produce
widespread showers and blustery winds Monday evening through
Tuesday, followed by generally drier weather and warming inland
temperatures mid to late week.

&&

.DISCUSSION...Low pressure will continue to track southeastward
from around the San Francisco Bay Area to western Arizona by
Monday morning. This will bring in drier and increasingly stable
air tonight into Monday morning, before the next storm system
approaches from the northwest. Already the better instability,
deeper moisture, and stronger forcing has shifted to our
southeast, where thunderstorm activity has been quite active
across portions of the southern Sacramento and San Joaquin
valleys. East to southeast flow around the departing low has
continued to bring shower activity back into our area. Enough
instability with daytime heating and the still cold air aloft,
along with lingering moisture, has allowed for decent shower
coverage across interior northwest California, particularly across
the mountainous terrain, with even some locally heavy downpours,
but no lightning. A few showers have made their way back to the
coast as well, but have been weaker and more isolated as they
track into more stable air. These showers will linger into this
evening, especially across the interior high terrain, but will
otherwise dissipate tonight, with clearing skies. It should turn
out to be a fairly nice evening along the Redwood coast, with
fairly mild temperatures and an easing onshore breeze.

Tonight the forecast challenge surrounds low temperatures across
the interior valleys, with guidance suggesting mid 30s for the
coldest spots of Trinity county and northeast Mendocino. Areas
like Hayfork and Ruth Lake may even approach freezing if skies
clear out early enough. Lingering low level moisture from the
recent rain could result in some fog development as skies clear
and winds calm in the valleys, which could keep temps milder and
limit fog development. However, last night saw more low cloudiness
in these areas than we are expecting tonight and those locations
reached into the upper 30s to around 40, so it will not take much
to reach frosty levels. Have left the current Frost Advisory as
is.

Meanwhile, along the coast, weak onshore flow and increasingly
stable air, along with the lingering low level moisture, will
likely allow for some stratus development. Clouds will likely
linger into tomorrow morning with some patchy drizzle, before some
offshore flow and increased mixing clears out the low clouds ahead
of the next system. Most of the area thus should see at least
partial sunshine on Monday, with a mainly dry day, before rain
begins to reach Crescent City and expand southeastward later in
the afternoon, quickly reaching across most of Humboldt and Del
Norte counties by the early evening. This system will have a
different track than the first couple of storm systems, with
stronger onshore flow and stronger forcing taking aim at the coast
from Cape Mendocino northward. Our past couple systems have
underperformed along the Redwood coast, with rainfall amounts
mainly around a half inch or less with each system around rain-
shadowed Humboldt Bay, as southerly winds have downsloped off the
nearby higher terrain. Do not expect that to be the case with this
system, with perhaps 1 to 1.5 inches from Eureka to Crescent City,
with 2 to locally 3 inches over the mountains. Numerous showers
will persist through much of Tuesday, before tapering off Tuesday
night, and will be mostly over by Wednesday morning. Wednesday
should turn out to be a drier day, with some some sunshine and
warming temperatures inland, but a chilly northwest breeze will
keep some areas feeling cool, especially along the coast.

The spell of wet weather and below normal interior temperatures
will moderate mid to late next week as this shortwave trough
carves out a large closed low over the Great Basin and high
pressure builds toward the west coast. Ideally this is a really
good SETUP for robust northerly flow. Northerly flow suggests cold
air advection and large scale sinking which does not bode well
for showers. Granted inland sites may still receive occasional
showers as perturbations pinwheel around this low. Temperatures in
the valleys will also start to rebound near seasonal normals
around mid week. GEFS as well as deterministic models indicate a
reinforcing shot of cold air toward for the weekend and a better
shot at showers...though rainfall amounts should not be as
prolific as we have seen this past week. 'Normal' May weather may
not return until the next week.

&&

.AVIATION...Low pressure system is continuing to move to the
southeast of the area. With enhanced instability over the area this
afternoon scattered showers have developed across the interior
however these showers are relatively weak and short lived. These
showers will come to an end this evening as daytime heating is lost
which should lead to mostly clear skies for the first part of the
evening. Late tonight, good radiational cooling combined with the
increased low level moisture from the recent rains will allow
widespread fog and low clouds to develop especially across interior
valleys where winds will be lightest. Coastal locations should also
see low clouds and fog tonight and as moist northerly flow develops
along the coast some light drizzle may occur early tomorrow morning.
After IFR to LIFR ceilings and visibilities early in the morning
conditions will become VFR late tomorrow morning. High clouds will
be on the increase ahead of the next weather system approaching the
coast tomorrow with light rain possible as early as late afternoon
across northern areas. /WCI

&&

.MARINE...Northerly winds have begun to develop across the waters
today as a low pressure center continues to move to the south of the
area. While winds will remain below 15 kts, seas will continue to
increase as a fresh west swell moves into the waters. This swell
will peak later this afternoon and gradually subside through the
evening. As the swell drops below 10 feet the small craft advisories
will be allowed to expire late this evening. Monday, southerly winds
will begin to develop across the area yet again as the last in a
series of fronts move toward the area. These winds will peak Monday
evening as the front moves through the area with northwesterly winds
developing on the backside. This system will usher in another large
mid period westerly swell that will peak Tuesday afternoon but keep
seas steep and hazardous through Wednesday morning. Upper level
ridging will develop across the Pacific Wednesday morning and
persist through Friday morning which will usher in a period of much
stronger northerly winds near gale force. /WCI
