Area Forecast Discussion
National Weather Service Spokane WA
1034 PM PDT TUE AUG 19 2014

.SYNOPSIS...
In the wake of a cold front, the gusty winds, showers and
thunderstorms will decrease overnight. Cooler temperatures and
the occasional threat of showers and thunderstorms will linger the
rest of the week and into the weekend. However, the vast majority
of this precipitation will be in northeast Washington and the
North Idaho Panhandle.

&&

.DISCUSSION...
Updated the forecast to adjust for the evening convection.
Satellite shows an upper level trough rotating through eastern
Washington and responsible for the scattered thunderstorms. Radar
shows much of the convection is decreasing, but it may be slow to
depart or diminish. Dynamics aloft are strong and able to continue
the thunder threat beyond sunset. Thunderstorms will gradually
weaken and shift into north Idaho and western MT, meanwhile the
models show the potential for isolated convection to move over the
Blue mountains and LC valley overnight. Gusty winds will decrease
over night in the lee side valleys. /rfox.

.AVIATION...
06Z TAFS: Isolated showers and thunderstorms will slowly shift
east across northeast Washington into north Idaho through the
overnight hours, remaining north of KGEG and KCOE. Meanwhile,
isolated high based showers may creep over the Blue mountains to
the KLWS area overnight. Winds in KEAT and KMWH will gradually
subside, but expect them to pick up again with daytime heating
after 20z. Surface based instability will increase Wed afternoon
with the best chance of convection across the northern mountains.
Some of these storms may approach the KGEG-KCOE corridor after
21/00z. /rfox.
