Synopsis
Anticipate cooler and breezy weather today and Thursday. Hit or
miss showers and a few thunderstorms are possible in the northern
mountains this afternoon, while a better chance of showers and
thunderstorms is likely Thursday. Temperatures return to near
normal for the weekend with a small chance of mountain showers
that continue into early next week.

Discussion
Gusty winds continue today especially central washington...

today through Friday night: a pattern change will bring cooler
and more unsettled weather to the inland NW for the next several
days, as high pressure aloft is replaced by an area of low pressure.

A dry cold front will mark the initial change as it pushes
through the region today with gusty breezy winds persisting for
much of the day, especially for much of central washington coupled
with dry humidities. The strongest winds will span from the
wenatchee area and waterville plateau to the moses lake area with
wind gusts of 45 mph this afternoon and a wind advisory continues
for this area until this evening. Temperatures will be noticeably
cooler by 5 to 15 degrees, with highs topping out in the mid 60s
to mid 70s. It's been about 9 days since these below normal
temperatures have been experienced. Water vapor satellite is
picking up on high level wave clouds spreading east of the
cascadesand will mostly likely linger into the morning hours.

The upper level low pressure trough over b.C. Will sink in from
the northwest with an increase of mid level moisture. Instability
will increase this afternoon with most unstable CAPE values 200 to
300 j kg and bulk shear of 40 kts across the okanogan highlands
to northeast washington and the idaho panhandle. Anticipate post-
frontal isolated showers and thunderstorms to develop this
afternoon and decrease by evening. Given the amount of low level
drying, measureable recitation will be limited but gusty winds
maybe possible near the storms. Winds will gradually ease
overnight, although gap winds in the cascades will continue the
breeziness. A northerly pressure gradient develops overnight into
Thursday, promoting increased north winds down the okanogan valley
into the western columbia basin. The upper trough of low pressure
will be over north idaho with as minor impulses and moisture
rotate through the region. Breezy afternoon winds return with
continued cooler temperatures. The deeper moisture will lead to a
better coverage of wetter showers especially across extreme
eastern washington into north idaho. Instability increases with
the potential for afternoon and evening thunderstorms embedded in
the shower activity. Snow levels will dip to near 5000 ft, leading
to light mountain snow in the higher elevations, especially of
the northern cascades. The upper trough releases its grip on the
region by Friday as high pressure builds in from the west.

Moisture and instability will linger with another round of
convection for the afternoon and early evening, although most will
be found in the mountains. Friday's temperatures will experience
a slight rebound while lighter winds are expected. Rfox.

Saturday and Sunday: the upper level trough which is forecast to
bring chilly weather to our area on Thursday and Friday will finally
exit to our east on Saturday. As it kicks out, the pacific
northwest will be under quasi-zonal flow although no notable
shortwave forcing will be present. Given that dew points will be in
the 40s and low 50s, orographic forcing should be enough to generate
afternoon showers and weak thunderstorms mainly over the higher
terrain. Zonal flow will continue for Sunday while an upper level
low originating from the gulf of alaska inches down the british
columbia coast. In terms of weather, Sunday should be similar to
Saturday albeit slightly cooler as subtle cold air advection is
realized over our area. In addition, areas up against the lee side
of the cascades will likely see increased winds Sunday as onshore
gradients tighten from the approaching aforementioned low.

Monday-Wednesday: deterministic models and ensembles continue to
bring this upper level low pressure down the west coast next week
but differ on positioning. By Wednesday, the GEFS keeps this
feature off the wa coast, around 131 w, while the ec ens positions
it right along the or wa coast. If this low does track a bit closer
to us, we could be looking at a wetter pattern but for now, just a
chance of showers exists for the higher elevations each day while
the lower elevations will remain mostly dry. It does stand to
reason that with this unsettled weather pattern most locations will
see a bit of precipitation at some point next week. However, it is
difficult to pinpoint when and where that will be so low pop chances
continue through the extended. Wilson

Aviation
12z tafs: sporadic gusty winds early this morning will become
widespread during the day with gusts peaking this afternoon to
early evening. Some local wind shear is possible this morning
before the MAX gusts mix to the surface. The strongest winds are
expected at keat with gusts up to 40 kts. An unstable atmosphere
may promote scattered showers over the northern mountains and
vicinity of kgeg-kcoe this afternoon and early evening. Winds will
decrease overnight in most locations.
