.SYNOPSIS...An upper-level trough will track south over the
area today with low level onshore flow. It will remain near the
region Monday and push eastward on Tuesday, bringing some increased
shower chances near the mountains. Brief high pressure around
midweek, bringing warmer and drier conditions. Another
disturbance drops across the region late in the week.

.SHORT TERM /TODAY THROUGH TUESDAY/...Forecast remains on track
this morning as an upper trough continues to slide toward the
region. This will maintain partly to mostly cloudy skies across
much of the area, though areas that see stratus lift first may
end up with a little more sunshine. We`ll see some light showers
cross the region today, particularly near the coast and in the
mountains. Can`t rule out an isolated thunderstorm or two,
especially in the North Cascades where there`s around a 10-15%
chance of seeing lightning this afternoon or evening. Daytime
highs likely top out in the lower 70s for the interior and 60s
along the coast - a few degrees below average for late July.
Shower chances will continue overnight into Monday morning,
especially south of Puget Sound and in the mountains, with up to
around a tenth of an inch of rain possible in the spots that see
the most. Remainder of previous short/long term sections follows
unchanged.                                Cullen

Nighttime lows are forecast to bottom into the lower to mid
50s. Upper-troughing remaining overhead on Monday as it
continues to sink south. It`ll gradually progress on Tuesday as
models have it crossing east of the Cascades by the evening.
Shower and isolated thunderstorm chances along the mountains
remain stubborn during this time, but temperatures will embark
on a warming trend - topping out near average in the mid 70s to
near 80 F. Overnight lows again in the 50s.

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...A warm up towards mid-
week appears likely as we`ll be on the backside of the trough with
transient ridging tracking overhead. Wednesday will bring the
warmest temperatures of the week with highs topping out in the mid
to upper 80s. The flow will then turn more zonal on Thursday
before broad troughing arrives towards the weekend with a
subsequent cool down. Conditions look to trend mostly dry during
this time.

.AVIATION...West to northwest flow aloft will turn light and
variable later today as upper low digs southward over Western
Washington. Onshore flow will continue in the low levels. Areas of
MVFR will lift to VFR most areas away from the coast this afternoon.
A few showers will be possible late this afternoon and evening near
the coast and across southern portions of the area as an upper level
disturbance digs southward over the area.  Areas of MVFR will
redevelop again overnight tonight.

KSEA...Satellite trends indicate areas of BKN020-030 have
scattered out at the terminal this morning. VFR will continue
throughout the rest of the day, with high level clouds streaming
ahead as an upper trough settles over the region. Ceilings will
lower again overnight with ceilings right around the MVFR
threshold for daybreak on Monday with a few light showers in the
vicinity. Surface winds S/SW 4 to 7 knots veering W/NW late this
afternoon.

.MARINE...A weak low pressure system will move southward across
the waters on Sunday. Surface high pressure over the northeastern
Pacific will then rebuild with lower pressure east of the Cascades
for varying degrees of onshore flow. Another trough approaching
British Columbia will lead to an overall increase in onshore flow
with possible westerly gales in the strait by around Thursday.
