805 pm pdt Thu may 23 2019

Synopsis A low will drop south from british columbia on Friday,
bringing a chance for light showers across the 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 Some shower activity
continues this evening with northwest flow aloft carrying some
it off the olympics across hood canal and the southern fringes
of puget sound. Little in the way of showers remain over the
cascades with the atmosphere stabilizing as the Sun GOES down.

Shortwave sinking southward over the interior of british columbia
will carve out a decent trough over washington by Friday afternoon.

The vast majority of the precipitation will likely be focused over
higher terrain, but it will certainly bring plenty of clouds and the
associated increase in onshore flow will help drop temperatures
across the interior of western washington 10 to 20 degrees below
today's readings. 27
from previous discussion... 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.

Kovacik

Aviation Showers diminishing over the mountains as the Sun goes
down. Increasing low level onshore flow level will push stratus
along the coast across much of the interior of western
washington by daybreak Friday. MVFR CIGS are likely. An upper level
shortwave trough will bring scattered showers to the area on Friday.

33 27
ksea...VFR conditions tonight, then stratus clouds moving in
11-14z for MVFR cigs. A few showers possible by 18z as upper trough
settles over the region. Surface wind light southwesterly
backing to southerly overnight and increasing to 10-15 kt
Friday morning. 33 27

Marine Onshore flow continuing to increase this evening.

Uil bli gradient was near +3.0 millibars as of 02z and
continuing to edge upward. Have upgraded the SCA in the central and
eastern strait to a gale warning through late tonight. Small
craft advisories in effect for the coastal waters, the northern
inland waters, and admiralty inlet. 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 27

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
