Area Forecast Discussion
National Weather Service Spokane WA
232 PM PDT WED JUN 8 2016

.SYNOPSIS...
Strong to severe thunderstorms are likely through evening across
southeast Washington and the southern Idaho panhandle. Gusty winds
will be from the Cascade valleys into the Columbia Basin. This is
all due to a cold front that will move through the region this
evening. Cooler, breezy and showery weather will develop over the
Inland Northwest for Friday and through the weekend. A slow
warming trend is anticipated for early next week.

&&

.DISCUSSION...
The remainder of the afternoon and evening hours...the focus will
be on strong to severe storms across southeastern WA and the
Idaho Panhandle. The cold front is traversing the CWA a bit slower
than expected and has allowed sufficient heating south of a line
from Clark Fork to La Crosse. This could mean two things, the
threat for strong storms will arc further to the north and west
than previously expected and the threat for strong storms may
linger longer into the evening. As such, per coordination with
surrounding offices and the storm prediction center, a severe
thunderstorm watch will be issued for the aforementioned areas
through this evening for storms capable of damaging winds and
large hail. These storms will also be capable of heavy rainfall
but the storm motion is so fast that it will take training storms
in the event to get flash flooding so will hold off on any flood
highlights at this time.

For the remainder of Central and NE Washington and far N Idaho
Panhandle, the threat for strong storms is much lower. There will
be a few embedded storms at times but the main issues will be
scattered showers along a slow moving frontal band and gusty winds
capable of fanning any new fire starts from earlier lightning /sb

Thursday through Sunday: A cooler and showery weather pattern
will be over the Inland NW for the later half of the week and the
upcoming weekend. In the wake of strong cold front this evening,
an upper level low pressure system will roll into the Pacific NW
and settle in for the weekend. The strong to severe convection
from this evening will wane overnight over the Idaho Panhandle.
Gusty winds will persist from the lee side Cascade valleys into
the Columbia Basin overnight and taper off by Thursday morning.
Gusty winds will develop again Thursday afternoon with speeds to
20 mph. The models show a secondary front with an embedded
shortwave will round the trough and reach the Cascades by 00z
Friday. Surface based convection will develop over the Cascades
Thursday afternoon and ahead of the feature over the Blue
mountains, but it will not be at the caliber of those seen today.
Instability and sheer will be less and as the colder trough moves
in, anticipate more showery conditions with isolated embedded
thunderstorms. This band of showers will accompany the shortwave
and move across eastern Washington Thursday afternoon, and then
stalling over extreme eastern Washington into north Idaho by
Thursday evening and Friday. Did raise pops for Thursday night
into Friday to support the better chances of precipitation. The
cloud cover and precipitation will keep temperatures on the cool
side on Friday and did push temperatures down slightly for Friday.
By Saturday, the upper trough will swing through Washington, but
models are differing on the track of its center. The ECMWF
indicates a northward track of the low across BC, while the GFS
and GEM show this feature lingering over Washington into north
Idaho for the weekend. Did opt for a compromise of the model
solutions, kept shower coverage diurnally driven over the higher
terrain. Could still see a hint of thunderstorms especially over
north Idaho. Across the lowlands of the Columbia Basin, shower
chance will be minimal. Cool and below normal temperatures will
prevail through the weekend. /rfox

Monday through Wednesday: Swift SW stearing flow will produce a
number of short-wave troughs that will introduce isolated to
scattered showers and thunderstorms each day.bz

&&

.AVIATION...
18Z TAFS: A cold currently stalled across Central/NE WA will
continue to focus elevated showers and t-storms through 20z. The
front will begin to make a move east around 21Z and interact with
deep instability along an axis from NE Oregon and NW Montana.
Clusters of t-storms are expected to develop across Ern WA and N
ID impacting Spokane-Cd'A but the threat for scattered strong to
severe storms will focus along and south of Walla Walla to Pullman
to Mullan including the Pullman and Lewiston terminals. Chances
increase further even further south. These storms will be capable
of damaging winds and large hail btwn 21-02Z. Gusty west winds
will develop behind the front with the potential for sustained
speeds 15-25 and gusts near 30 mph. Some guidance is indicating
strong speeds for Wenatchee arnd 00z so this will be monitored for
future updates. /sb
