Synopsis Rain and mountain snow showers will continue through
this afternoon. A series of weather systems will move through
western washington through Tuesday of next week. High pressure
aloft will bring mainly dry weather for the second half of next
week.

Short term today through Monday The first focus this morning
has been on snow levels, most notably over snoqualmie pass where
snow accumulations have been noted down to around 2200 feet on the
trees and as low as 2700 feet on the road. Adjustments were made
to the forecast through this afternoon to account for this.

General consensus is that snow levels should rise by about 1000
feet this afternoon, likely above snoqualmie pass allowing
precipitation to transition back to rain. However, heavier
convective showers could pull snow levels down temporarily. Snow
will likely continue at the higher passes this afternoon. That
said, steady precipitation should become more showery in nature,
leading to variable additional snow accumulations.

The next focus is on the potential for isolated thunderstorms this
afternoon and evening. Currently, CAPE values of 100-300 j kg are
present along the coast and in the coastal hills. While no
thunder has been detected over the washington in the last several
hours, there have been a few strikes detected in oregon. Chances
for isolated thunderstorms will spread into the puget sound
lowlands this afternoon then diminish this evening. Peak cape
values between 300-500 j kg are forecast to develop near a
potential pscz this afternoon. As always, determining the exact
location of a pscz is difficult, but consensus puts it somewhere
in king or southern snohomish county. We will continue to monitor
this situation through the afternoon. -wolcott-
from previous discussion:
after a lull tonight, another system will bring more rain on
Sunday. There will be another brief break Sunday night followed by
a third system on Monday. The Sunday system will bring more snow
to the higher passes but probably not as much as the one today.

Snow levels will rise above the highest passes on Monday.

It will also be breezy to windy at times the next few days as
weather systems move through but nothing very impactful. Lastly,
temperatures will be a few degrees below normal today and Sunday
and then warm to near normal on Monday. Schneider

Long term Tuesday through Friday It will dry out on Tuesday
as the last in a series of weather systems heads inland and high
pressure aloft begins to build in from the west.

The rest of the week looks largely dry with an upper ridge over
the area. A system passing to the north might clip the area on
Thursday but it probably won't amount to anything this far south.

Another, somewhat stronger system passing to the north on Friday
will flatten the upper ridge and could bring some showers, mainly
north part. Temperatures will be seasonable through the period.

Aviation An upper level trough will continue to move through
the region this morning. Flow aloft will become northwesterly
today, while onshore flow will persist at the surface. The air
mass remains moist and somewhat unstable. Current radar indicates
widespread rain across the region at this hour. Expect widespread
showers to continue into the early afternoon hours. Thunderstorms
will be possible this afternoon as the airmass becomes a bit more
unstable. Mixed bag of current conditions across the terminals at
this hour, with most terminals eitherVFR or MVFR in the vicinity
of showers. Expect areas of MVFR and isolated areas of ifr to
persist in heavier showers. Low level onshore flow will allow for
a potential convergence zone to form near the king snohomish
county line. Some improvement toVFR conditions are expected for a
period late this afternoon and evening before ceilings sink back
to MVFR across much of the region late tonight.

Ksea... Current conditions MVFR with periods of showers to
continue through the morning hours. Should see some improvement in
ceilings near or after 21z. Most convergence zone activity this
afternoon should remain north of the terminal. Increasing low
level onshore flow could lead to some gusty surface winds from
midday into early evening. Surface winds s- SE 5 to 10 knots
becoming SW 10-15 gusting 20 knots from 18z through 01z. 27 14

Marine A trough over the coastal waters will move ashore this
morning, allowing for onshore flow to increase. A gale warning
remains in effect this afternoon and evening for the central and
eastern strait of juan de fuca associated with a strong westerly
push down the strait. In addition, small craft advisories remain
in effect the coastal waters, the western strait, and admiralty
inlet. Have added a small craft advisory for gusty southwesterlies
in the southern sound and gusty northwesterlies in the northern
sound in the wake of this system. A warm front will reach the area
on Sunday, with another frontal system approaching the area on
Monday. Onshore flow Tuesday will diminish by Wednesday as high
pressure builds over the area. 14

Hydrology River flooding is unlikely over the next 7 days.

However, rainfall will cause rises on area rivers.
