Update A dry high pressure system over the E pac will dominate
the areas weather for the next several days. Dry conditions and
near normal temps can be expected today before a warming trend
develops into the weekend. Afternoon high temps for the latter
part of the weekend are forecast to climb into the mid to upper
90s over portions of the columbia basin on Sunday.

Aviation 18z tafs...VFR conditions are expected through the
period. An upper level ridge will keep the region under a
dry... Northwesterly flow. Winds will generally be less than 10 kts.

However... Winds at krdm and kbdn will be 10 to 15 kts with higher
gusts during the afternoon and early evening hours. Earle

Prev discussion issued 434 am pdt Thu jun 22 2017
short term... Today through Saturday... An upper level ridge will
build over the eastern pacific ocean today through Saturday. The
building ridge will keep a dry northwest flow aloft over wa and or.

Subsidence associated with the ridge will push any disturbances to
the north. It will also keep skies mainly clear... Create a warming
trend... And keep winds light. Clear skies, dry airmass, and lighter
winds will lead to wide diurnal swings with below normal overnight
temperatures and 30-40 degree warming during the daytime heating
with 15 plus hours of sunshine. Thermal banding will raise
temperatures on the ridges for Friday night and Saturday due to
warmer air aloft. Coonfield
long term... Saturday night through Wednesday... The upper level
ridge looks to be over the pacific northwest Saturday night through
Monday. This ridge should slowly drift east during this period.

Conditions look to be fair and dry Saturday night and Sunday with
temps continuing to increase, both the overnight low and the daytime
high. A weak upper low looks to develop west of northern california
during this period as well. As such should see increasing moisture
advection that could lead to a few showers or thunderstorms Sunday
night into Monday morning. These showers and storms would mainly be
over central and north-central oregon. The upper low then looks to
weaken and kick east across the area Monday afternoon and night in
response to a stronger low moving into western canada. Thus a few
showers and thunderstorms would continue to be possible over
portions of the area, mainly central and northeast oregon. Monday
should continue to be very warm, especially over the eastern three-
quarters of the area. Drier, cooler and breezy conditions look to
return for Tuesday and Wednesday due to a westerly onshore flow. 90

300 am pdt Sun jul 3 2016

Short term Today through Tuesday... A stable westerly flow will
persist through tonight. There will be just enough moisture and
instability for possible afternoon and evening showers over the
washington cascade east slopes. Elsewhere it will remain dry with
just some cloudy skies. It will become breezy to windy in the
afternoon in most of the cwa... But the strongest winds will be in
the lower columbia basin and adjacent valleys. The kittitas valley
will have the strongest winds in these locations with a wind
advisory in effect from 8 am until 8 pm. With the chilly
temperatures tonight combined with decreasing wind it will become
quite chilly. Then on Monday and Tuesday there will be a cooling
trend with temperatures back to near normal by Tuesday. It will be
breezy to windy again on Monday and Tuesday afternoons... But with
speeds below wind advisory criteria. Still there could be some gusts
of wind that may move some things like lawn furniture and canopies
during your 4th of july picnic... So stay tuned to the latest
weather forecasts and possible wind advisories. 88

Long term Tuesday night through Sunday... The extended period
starts off dry for most of the forecast area Tuesday night. Then an
upper level low will drop southward across washington state and
possibly northern oregon. There remain some model differences in
just how far south this upper low will move before it slides east
into id mt. The latest ECMWF trended toward the GFS solution which
would bring the low into northern oregon Wednesday
afternoon evening. The forecast was therefore trended in this
direction and a slight chance of showers t'storms was introduced
across the washington east slopes, n. Blue mtns and wallowa county.

With this low moving through, sky cover was bumped up into the
partly cloudy range for much of the cwa... Except central oregon
where it is expected to remain mostly clear. Winds will be breezy at
times on Wednesday and temperatures will fall back to below average
levels. This means highs in the mid-70s to lower 80s in the
valleys basins with only 60s and lower 70s mountains.

After a short break in the active weather on Thursday (and slightly
warmer temperatures) the remainder of the extended period is now
looking rather active... Especially for july. By Friday the latest
model guidance was in good agreement that a plume of moisture would
move into the forecast area out ahead of a large upper low trough
situated in the gulf of alaska. The latest ecwmf was more bullish
spreading steady light rain over the western half of the
area... While the GFS brought only showers for Friday. Took a blend
of these two scenarios but leaned toward the wetter ECMWF solution
due to the strength and size of this mid level moisture plume.

Heading into next weekend the latest guidance is now in good
agreement that the above mentioned upper low will spin offshore
before slowly moving over the pacific northwest by Sunday. This low
will have plenty of moisture to work with along with a strong upper
jet (125 kts at 300 mb). Therefore trended the forecast wetter with
more clouds during this period areawide. The exact details of this
storm system remain to be seen, however if this scenario plays out
close to how the current models have it, there will likely be
periods of steady rain for at least parts of the area. It will
remain breezy to locally windy next weekend as this system moves
through. On a final note temperatures will be well below average for
mid-summer. Expect highs only in the 70s for the valleys basins on
Sunday... With only upper 50s to 60s mountains. 77

Aviation Previous discussion... 06z tafs. Mainly clear skies for
the next 24 hours. Winds tonight 5-15kt. Winds Sunday 15-30kt.

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