445 PM PDT SAT AUG 30 2014

.SYNOPSIS...
The Labor Day weekend will be cooler than normal, with locally
breezy conditions. Aside from isolated showers, the majority of
the Inland Northwest will remain dry. A continued cool pattern is
expected through the middle of next week, with the best chance for
showers and thunderstorms Wednesday. Relatively warmer, drier
weather is forecast late next week.

.DISCUSSION...
Update: As of 430 pm composite radar imagery showed a line of
showers and thunderstorms moving into the Blue Mountains east of
Walla Walla. Individual cells were also developing around
Lewiston and the Camas Prairie. With SPC analysis indicating CAPE
values around 500 J/KG over southeast Washington its expected that
storms will impact the Lewiston area, Blue Mountains, and Camas
Prairie through the early evening. Gusty winds...brief heavy
rain...and possible small hail can be expected with these storms.
The forecast has been updated to mentioned isolated storms in
these areas. Meanwhile westerly flow off the Cascades is resulting
in dissipating cumulus over the Wenatchee area and with models
showing drying aloft into the evening have removed isolated
showers in this area. JW

.AVIATION...
00Z TAFS: A weather disturbance moving into northeast Oregon will
clip southeast Washington early this evening with scattered
showers and isolated thunderstorms around KLWS with possibly a few
showers also occurring at KPUW. Storms should dissipate around 03z
with loss of daytime heating and exiting weather disturbance.
Increased low level moisture and upslope on the palouse may result
in MVFR stratus deck between 10-16z Sunday per NAM soundings.
Elsewhere VFR conditions expected with spotty hit and miss showers
mainly over the mountains...and possibly a few light showers
around KGEG/KSFF/KCOE.  JW
