Area forecast discussion 
National Weather Service Spokane Washington
1033 am PDT Friday Sep 4 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 portions of eastern
Washington on Saturday. Drier and warmer weather is expected by
early next week.

Discussion...
the forecast has been updated to include patchy fog over the
southern Palouse around Uniontown, the Camas Prairie, and the
central Panhandle valleys south of Interstate 90 per web cams and
visible satellite imagery. Also, models have backed off on the
instability this afternoon around Wenatchee and Omak with the best
instability in the Cascades. Thus...the slight chance of
thunderstorms for the afternoon was removed in the valleys of
north central Washington but kept for the high terrain. Jw

Aviation...
18z tafs: instability resulting from having an area of low
pressure within close proximity to the forecast area keeps both
stratiform and convective cloud cover in the forecast through much
of the time interval. In addition showers and some thunderstorms
remain mentioned this afternoon and early evening but the wettest
interval is to occur overnight tonight and on into tomorrow as a
wet occluded frontal zone pivots and wraps a bit around the edge
of the low which keeps in in place over eastern Washington and
north Idaho from about 9z on and beyond. /Pelatti
