Area Forecast Discussion
National Weather Service Spokane WA
827 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: The upper level disturbance that brought a cluster of
showers and thunderstorms to northeast Oregon is moving away from
the area this evening. An outflow boundary was generated from this
convection which as it moved north towards the palouse generated
some additional cells with a few lightning strikes noted between 6
pm and 8 pm north and northeast of Pullman. These cells have
weakened in the past half hour with the loss of daytime heating.
For the remainder of tonight the northwest flow and moistening low
level air mass will produce upslope showers into the Central
Panhandle Mountains. Elevated mid level instability will also be
present in this area especially this evening. Meanwhile a few
showers associated with an upper trough in British Columbia will
clip far northern Washington and Idaho with a bit of mid level
instability aiding in these showers persisting into the overnight
hours. Some other minor forecast updates have been made to low
temperatures and winds based on latest trends. 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
