Synopsis Weak ridging will allow for dry conditions across the
lowlands this afternoon, with scattered showers and isolated
thunderstorms across the mountains. On Friday, a low will drop
south from bc, bringing a better chance for light showers across
the entire area, with isolated thunder possible near cascade
crest. Another low drops south for Saturday for an even better
chance for showers. Another ridge builds in for Monday, memorial
day, with dry and warm temps expected for the lowlands and
isolated showers storms for the mountains. Ridge holds through
late week, with an overall dry forecast tues-thurs.

Short term tonight through Sunday As of 21z this afternoon,
the synoptic scale pattern was characterized by a broad area of
low pressure across the western us, with center in the vicinity of
salt lake, with a strong ridge of high pressure located
downstream across the southeast us, while a weaker area of high
pressure remains located across the north pacific. At the sfc, a
broad area of high pressure was noted across the north pacific,
with a sfc cyclone located across the central rockies in
association with the large area of low pressure across the west,
while high pressure exists across the southeast.

The weaker mid and upper level area of high pressure across the
pacific is responsible for beautiful lowland weather across
western washington for most, as ridge influence induces large
scale subsidence, allowing for clear skies. Temperatures have also
warmed nicely into the 70s this afternoon. Despite this, there
still exists a few "problem" areas this afternoon-one being the
stubborn stratus along the coast and portions of the strait of
juan de fuca. Had expected this to burn off by early afternoon,
and although it has made notable improvement since the morning
hours, there may be areas that do not completely break out. That
being said, continued erosion progress is expected over the
coming hours. In addition to this, showers and isolated
thunderstorms have developed across the foothills and higher
terrain. Some of the activity is advecting in from bc as well.

This corresponds well to a sliver of 500-1000j kg SBCAPE per spc
mesoanalysis from the central and northern cascades into bc.

Expected isolated lightning to be a hazard with any convective
storm that develops. Steep low level lapse rates of >8c km carry
the threat for locally gusty winds downbursts as well.

Activity threat for thunder will increase thru the afternoon
hours, peak in the evening, and dissipate after sunset. Typical
diurnal, single cell convective characteristics overall, tho a
few cells may merge together and form disorganized clusters.

For tomorrow, a shortwave will drop down from bc right over
washington. The chance for scattered showers across both the
mountains and the lowlands will increase early Friday morning from
the north. Although it will not be a washout by any means,
scattered showers will continue thru much of the day and spread
southward as the low tracks in that direction. Right now guidance
indicates most of the instability will remain confined to the
cascade crest and points east, have placed mention of thunder at
least in the northern cascades for now given that mid level temps
will be cooler as the low moves directly overtop the area.

Following very closely on the heels of Friday's low will be
another, stronger closed low for Saturday. Some timing differences
exist between the deterministic ec and gfs, and right now prefer
the slower progression of the ec based on ensemble guidance. This
could make for a later start (i.E.,afternoon vs morning) to the
next round of precip on Saturday if this were to verify, but
nonetheless, unfortunately the forecast for Saturday has turned
wetter. Have also kept mention of thunder in the cascades. This
low will pull south Sunday night and reinforce that persistent,
longer wave western us trough.

Kovacik

Long term Monday through Thursday The long term period begins
on memorial day with the previous day's low well to our south
centered in northern arizona. This allows a ridge to build into
the pacnw, which points towards a return to dry and pleasant
weather, at least for the lowlands with highs back into the mid
and upper 70s. The higher terrain could again see diurnally
driven convection by Monday afternoon but it seems more isolated
at this time. The ridge appears to hold on thru the remainder of
the long term. This may allow for a dry forecast by Tuesday
evening (after another round of afternoon mountain convection)
through Thursday.

Aviation Isolated thunderstorms will form over the cascades
this afternoon and evening, then diminish. Meanwhile, low level
stratus clouds along the coast will push inland tonight with
onshore flow - MVFR CIGS are likely. An upper level shortwave
trough will bring scattered showers to the area on Friday. 33
ksea...VFR conditions tonight, then stratus clouds moving in
11-14z for MVFR cigs. Light south winds, increasing to 10-15 kt
Friday morning. 33

Marine Onshore flow will increase tonight with small craft
advisories in effect for the coastal waters, the strait of juan
de fuca and the northern inland waters. Strong northwest flow
will develop over the outer coastal waters on Friday with gales
possible. Winds will ease on Saturday and become light on Sunday.

Onshore flow will increase again on Monday. 33

start of the next rainy season; it will only be updated as needed
