.SHORT TERM /TONIGHT THROUGH FRIDAY/...Shower activity this
evening is mostly tied to the central sound due to a Puget Sound
Convergence Zone. May continue to see isolated t-storm activity
through 06z, with showers lingering through around 09-11z. 33

Previous discussion...The trough will settle further southward
over the area on Wednesday, but low level onshore flow will
decrease. This will make the higher terrain more of a focus point
for diurnally driven shower activity. By later Wednesday evening,
remaining showers should die off with some partial clearing as the
center of the upper trough drifts south and eastward.

There is some possibility for some moisture to wrap around the
upper trough on Thursday, but this would most likely affect mainly
the Cascades with some afternoon showers or an isolated
thunderstorm. The remainder of the region should be mostly dry
with some added sunshine across the northwestern half of the
forecast area by afternoon as the upper low pulls further away.
Weak upper ridging noses into the area on Friday with the low
level flow becoming only weakly onshore. This should give most
areas a mostly sunny day with high temperatures bouncing back to
near or even a smidge above normal.

.LONG TERM /SATURDAY THROUGH TUESDAY/...Upper ridging remains in
place on Saturday for another dry day with temperatures similar to
Friday if not a couple degrees warmer in spots. Some model runs
attempt to wrap some moisture back toward the region on Sunday
around a broad upper trough over the Intermountain West. That is
not a favorable setup to develop much in the way of precipitation,
but it does warrant the return of a chance of showers to the
forecast.

By early next week, model ensembles are in relatively good
agreement with weak upper troughing taking up residence along the
British Columbia coast. It doesn't look like a particularly wet
scenario, but cyclonic flow aloft and persistent low level onshore
flow will keep some clouds in the forecast along with a chance of
showers and temperatures a little below normal for late May. 27

.AVIATION...Westerly flow aloft will become light Wednesday as
upper level low moves overhead. At low levels, onshore flow with
northerlies through much of the interior will continue through
Wednesday.

The 4000-7000 broken layer will lower a bit overnight and linger
into Wednesday morning for much of the area - except the convergence
zone where ceilings will trend a bit lower with rain. The
convergence zone currently is oriented from the central Kitsap
Peninsula northeast into the Cascades - extending right between KBFI
and KSEA. It may slowly move south through the early Wednesday
morning before dissipating 12z-15z Wednesday.

KSEA...Scattered to broken layer near 43000 feet. Lower ceilings
with rain will are expected with the convergence zone in the
vicinity. Northerly winds 4 to 8 knots.

.MARINE...Persistent onshore flow through the weekend
with offshore high pressure. Typical small craft advisory westerlies
will develop in the central and Eastern Strait of Juan de Fuca in
the evening hours each day with possible small craft advisory winds
extending into the adjacent waters into the weekend.

&&

.HYDROLOGY...The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.
