Area Forecast Discussion
National Weather Service Spokane WA
934 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...
00Z TAFS: A cluster of thunderstorms will be in the vincity of the
KGEG-KCOE corridor through 02z with gusty west winds, brief
downpours and small hail. Meanwhile the bulk of the convection
will lie across the northern mountains and near KMLP. The
convection should decrease after 06z. Gusty westerly winds will be
enhanced in KEAT, KMWH, KPUW and KWS while thunderstorms induced
gusts will be found from KGEG-KCOE. VFR conditions are expected
overnight into Wed morning. Another round of showers/thunderstorms
are possible Wed afternoon mainly in the mountains. /rfox.
