Synopsis...
expect cool, breezy, and showery weather this week. The most
widespread precipitation will likely occur Tuesday night into
Wednesday with the potential for a half inch or more of rain over
portions of the Idaho Panhandle and southeast Washington. Mountain
passes could see a few inches of snow late Wednesday. A ridge of
high pressure next weekend has the potential to bring the region a
day or two of drier weather.

Discussion...
evening update: showers continue to decrease this evening with the
loss of daytime heating and no good forcing or instability to keep
showers going. A band of showers over NE Oregon has had a hard
time making it into southeast Washington except in the Blue Mountains due
to the southward track of the upper low in central Oregon this
evening. The forecast has been updated to refine pop's for tonight
based on current radar trends...with the main adjustment to lower
pop's a bit for the Pullman and Lewiston areas. Jw

Aviation...

06z tafs: the boundary layer has moistened to near saturation this
evening across NE Oregon extending northeast into the Palouse.
With low level upslope winds persisting models show stratus
lowering and expanding on the Palouse tonight before spreading
north into kgeg/ksff/kcoe overnight. IFR conditions are expected
to develop near 08z kpuw and 13z kgeg. MVFR stratus is expected
for kcoe/ksff although near saturated conditions at the surface as
of 06z could result in patchy fog prior to stratus moving in from
the southwest. Stratus will lift mid to late morning with VFR
conditions expected for all taf sites Tuesday afternoon with
afternoon showers possible for the eastern taf sites. Jw
