Area forecast discussion 
National Weather Service Spokane Washington
1046 am PDT Sat Aug 30 2014

Synopsis...
the Labor Day weekend will be cooler than normal with locally
breezy conditions over portions of central and eastern
Washington. With the exception of some isolated mountain showers,
the majority of the inland northwest will remain dry through the
weekend. A continuation of the cool weather pattern is expected
through next week. The best chance for showers and thunderstorms
will probably occur in the Wednesday or Thursday time frame.

Discussion...
the next weather disturbance is bringing rain showers to western
Washington this morning. Regional radar shows precipitation just
reaching the Cascade crest as of 1030 am PDT. Most of the showers
will remain along and to the south of Stevens Pass and Highway 2.
The East Slope valleys may not see any precip due to downsloping
westerly winds. These westerly winds will add an upslope component
to the Idaho Mt zones, enhancing the threat of showers this
afternoon. So far there is no lightning associated with the
showers on the west side. The closest strikes have been in central
Idaho. It still appears that instability will be marginal at best
with greater likelihood of thunder north into British Columbia or
south in the central Idaho mts. Just minor changes made for this
update, mainly to sky grids and Max temps to account for recent
trends in observations. /Kelch

Aviation...
18z tafs: VFR conditions expected through 18z Sunday. A couple of
weak weather disturbances today will produce mainly mountain
showers. Breezy conditions will develop by early afternoon in the
Post frontal air mass. Models are hinting at some low level
moisture advection across southeastern Washington tonight. This is
expected to produce some mid level cloud cover across eastern Washington
and showers ongoing over the Idaho Panhandle. This should not impact taf
sites although kcoe and kpuw may see some vicinity showers 06z-12z
Sunday. /Ek
