Updated AVIATION discussion

.UPDATE...The latest radar was showing an area of showers along
and near the foothills of the Blue Mountains that was slowly
lessening in coverage. Isolated TSRA were embedded in the showers
that extended SW into Grant County and this area was drifting east.
The showers were in response to an upper level disturbance that will
track east with decreasing pops from west to east today.
The best chances for pcpn will remain over the Blue/Wallowa
Mountains this afternoon. Other than minor changes to wx and pops
and temps that are forecast to climb into the 80s with 70s in the
mountains...the present short term forecast appears more on track
now.

&&

.AVIATION...18Z TAFs...VFR for the next 24 hours at all TAF sites.
Isolated thunderstorms possible this afternoon in the Blue Mountains
and Wallowa County. Otherwise, drier mid levels and a more stable
airmass will move into SE Washington and central/north central
Oregon this afternoon thus killing any potential for thunderstorms
at TAF sites. Mainly SCT-BKN150-200 today, then clearing skies by
06Z. Sustained winds increasing to 10-15kt this afternoon with gusts
to 20-25kt at KDLS, KYKM and KPSC. Decreasing pressure gradients
after 05Z resulting in drainage winds less than 10kt overnight.

.PREVIOUS DISCUSSION... /issued 211 AM PDT Thu Jun 21 2018/

SHORT TERM...Today through Saturday...The upper trough will move
east over eastern WA and OR today. Showers and thunderstorms will
persist today in the unstable air ahead of the trough. Scattered
thunderstorms are occurring over central and north central OR this
morning. These storms will shift east this morning with the trough.
The heaviest showers will be over the central OR mountains
northeastward to the Blue Mountains. The trough moves east into ID
by evening and expect activity should decrease quickly. Thursday
night and Friday morning a transitory upper level ridge will develop
over WA and OR with fair and dry conditions over eastern WA and OR.
Friday afternoon a short wave will move through WA.This disturbance
may trigger some showers in the central WA Cascades with a few
showers in the extreme northwest corner of the CWA but the rest of
the area will remain dry with CU developing in the afternoon over
higher terrain. Breezy to windy conditions will develop behind the
trough in the Columbia Basin, Columbia River Gorge, and Kittitas
Valley as stronger winds aloft mix to the surface today. These winds
will decrease overnight then redevelop Friday/Friday evening. Above
normal temperatures today will cool slightly Friday and Saturday.
Coonfield

LONG TERM...Saturday night through Thursday...An upper ridge will
build over the region from the west with the ridge axis moving on
shore late Saturday night into Sunday. This will bring dry and fair
weather to the region until Sunday evening. Then an upper trough
will move into the region Sunday night, but with very little
moisture. It will bring mainly just some mid and high clouds and
increasing winds, along with some cooler temperatures for Monday and
Tuesday due to cloud cover and mixing. Sunday will be very warm to
hot with highs around 90 in the lower elevations...cooling to the
80s for Monday and Tuesday in the lower elevations. The upper trough
will linger over the region and it will be a rather broad trough
with dry air within in it. A zonal westerly flow will then develop
on Wednesday with slightly warmer temperatures and less wind. The
long range models are hinting at possible showers over the mountains
on Thursday, but due to model inconsistencies will leave it dry for
now with near normal temperatures for Thursday. 88
