Area Forecast Discussion
National Weather Service Seattle WA
304 PM PST Thu Feb 29 2024

.SYNOPSIS...Post cold frontal showers with occasional rumbles of
thunder will continue this afternoon via a surface trough over the
Pacific. Heavy snow will continue to fall across the Olympic
and Cascade mountains through early Friday. Widespread rain with
some snow mixed in will be widespread tonight for most lowland
areas, as temperatures drop to around freezing. The potential for
heavy snow-banding exists in the Olympic Interior, primarily
along the U.S. 101 corridor around the Olympics. Several more
rounds of precipitation are possible into next week, especially on
Monday.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY/...Synoptic setup depicts a
surface cold front in eastern Washington, with a surface trough
just off the Pacific coast with a low pressure centered off the
coast of B.C. Canada. An upper level trough with cooler air
sinking down (along with vorticity advection and low level
moisture) have been aiding the firing of afternoon convective
showers, with occasional isolated thunderstorms (via CAPE values
around 300 J/kg). These pop up storms have been very brief, and
have occasionally produced lightning strikes off the coast. The
threat will continue through the afternoon and early this evening.

The focus through the remainder of the period turns to winter
weather and cooler temperatures through Sunday. Thursday night
through Friday will be the wettest time period in the short term.
Heavy snow will continue across the Cascade and Olympic mountains
through the first part of Friday. Have extended the winter storm
warning for the Cascades (above 1000 feet) through 4 am Friday (up
to 10 more inches of snow with heavier amounts at elevations above
4000 feet), and the Olympics through noon Friday (up to 18 more
inches of snow).

The HREF ensemble models were depicting an increasing chance of
snow banding setting up with this next wave of precipitation ahead
of the surface trough going into tonight/Friday morning,
especially in lowland areas in the US-101 corridor around the
Olympics. A winter weather advisory was issued for the increased
likelihood of seeing accumulating snow of at least an inch or
more. Depending on where the convective snow banding sets up, it
is likely that some areas may receive a few more inches of snow.
It may not become clear until the snow begins falling as to who
will receive the most snow with this system. Additionally, some
areas may receive less snow than advertised (given the variability
of this system). Travelers should check road conditions before
traveling, and also listen for further weather updates (as the
system develops).

Additional weak systems will bring chances for mixed precipitation
showers Saturday afternoon and again Sunday afternoon. These are
not expected to be all day washouts. There will be a thunder
chance along the coast with these next systems. Winds are not
expected to be impactful, with south winds at 5 to 15 mph through
the weekend. Temperatures will approach freezing during the next
few nights, but highs will recover into the mid 40s.

.LONG TERM /MONDAY THROUGH THURSDAY/...The extended outlook (via
ensembles) is expected to remain cool and wet through the majority
of next week. There will be chances of rain and snow showers
throughout the week, but the wettest day in the long term appears
to be Monday with an upper level shortwave producing widespread
mixed precipitation across the region. Temperatures will remain
steady with highs in the mid 40s, and lows still hovering around
freezing in the low to mid 30s. Winds will remain light out of the
south (most likely around 5 to 10 mph).

HPR

&&

.AVIATION...A broad upper trough axis remains offshore with
southwest flow aloft over Western Washington. The air mass is moist
and somewhat unstable. A mix of VFR and MVFR ceilings in scattered
showers and isolated thunderstorms are expected across the region
today, with the best chance being along the coast. Additional
thunderstorms are possible in the Southwest Interior and Puget
Sound. A upper level disturbance embedded in the trough will move
onshore tonight for an increase in shower coverage along with gusty
surface winds. Some of the heavier showers will mix with snow across
the interior lowlands tonight. Heavier bands of snow are likely
overnight into Friday across the Olympic Peninsula and Southwest
Interior for periods of reduced visibilities and cigs.

Icing and turbulence in the airspace has been noted in recent pilot
reports this afternoon. This will continue as the airmass remains
cooler and unstable.

KSEA...Cool, unstable post-frontal air mass will lead to a mix of
VFR and tempo MVFR ceilings in scattered showers. An isolated
thunderstorm could pop up in the vicinity this afternoon, but
probability too low to include in the TAF at this time. Showers will
increase tonight. They may mix with snow near or after 08Z, but
significant accumulation is not expected. There could be periods of
slush on surfaces that develop in heavier showers. Surface winds
S/SW 7 to 12 knots...rising after 03Z tonight to 10-15 gusting 20-25
knots at times.

Kristell

&&

.MARINE...A broad surface trough remains over the coastal and
offshore waters this morning. There are a number of mesoscale
surface lows meandering offshore that will move onshore in the
vicinity of Vancouver Island through Friday night or Saturday.
This will continue to produce small craft advisory winds across the
coastal waters and much of the interior waters through Friday, as
such, current SCAs have been extended into Saturday. Winds will
gradually subside mostly below small craft advisory levels by early
next week as broad troughing over the region weakens and surface
ridging builds over the interior of British Columbia.

The active pattern offshore will continue to generate hazardous seas
over the coastal waters into Saturday before subsiding below 10 feet
early next week.

Kristell

&&

.HYDROLOGY...Precipitation will be more showery today into Friday
in the wake of a system that moved through the region. Snow levels
have fallen back towards 1000-1500 feet and will continue to
fall to below 1000 feet overnight into Friday. Some rises will
continue on area rivers, especially along reaches of the Chehalis,
so a Flood Watch remains in effect for Grays Harbor and Thurston
counties. A Flood Warning remains in effect for the Skokomish
River, which has crested in moderate flood stage and will continue
to recede through this evening and into Friday. 14
