Area forecast discussion 
National Weather Service Spokane Washington
1019 PM PDT Wednesday Sep 2 2015

Synopsis...
a cool and showery weather pattern is expected for the remainder
of the work week as a cold storm system moves by the area.
Widespread rain is expected in the Panhandle and extreme eastern
Washington on Saturday. Drier and warmer weather is expected by
early next week.

Discussion...
the front remains stalled over extreme southeast Washington and the
Panhandle of Idaho this evening but satellite and radar imagery
shows the band shrinking in areal coverage and precipitation is
much lighter than it was this afternoon. Surface observations
across north central Washington show drier air filtering down the northern
valleys where dewpoint temperatures have fallen into the upper
20s to low 30s. Winds have already shifted to the north down the
Okanogan Valley so I adjusted min temps down a bit across the
sheltered valleys where they are currently seeing mostly clear
skies and light winds. The rest of the forecast appears on track.

Aviation...
06z tafs: the surface boundary has moved a little south this
evening and is now draped over extreme southeast Washington and the
central Panhandle mountains of Idaho with some clearing north and
west of the front. Expect the front to finally exit the forecast
area by early Thursday morning with clearing skies in most areas.
Expect winds of 10 kts or less. The presence of the upper level
low, spinning over southeast British Columbia will keep some shower activity
over the Cascade crest and possibly across the northern tier but
precipitation is not expected at any taf site. /Ek
