Area forecast discussion 
National Weather Service Spokane Washington
801 am PST Friday Jan 30 2015

Synopsis...
areas of low clouds and fog will persist across portions of
inland northwest as high pressure remains in place. The ridge of
high pressure will begin breaking down Sunday. This will result in
and increased chance for valley rain and mountain snow through
the middle of next week.

&&

Discussion...
minor update made to increase the areal coverage of dense freezing
fog on the West Plains between Wilbur and Airway Heights as well
as to add a mention of patchy freezing drizzle around the Spokane
area which has led to slick roadways in some places. Also have had
reports of flurries in Omak as well as near Moyie Springs coming
out of the stratus layer so flurries were added for the northern
valleys. Jw

Aviation...
06z tafs: light winds and clear skies aloft will continue to bring
widespread restrictions from fog and stratus through the next 24
hours. Fog will impact kgeg/ksff/kcoe/kpuw and possibly klws
while keat/kmwh will largely contend with stratus. Minor
improvements will be noted at all sites as the fog lifts to more
of a stratus deck midday, but all sites will stay in IFR or MVFR
conditions. The stratus is expected to lower once again late
evening as low level inversions strengthen. Some light drizzle
late in the evening for the kgeg/ksff/kcoe sites will be possible
as a weak shortwave passes to our north. Overnight expect the
return of IFR/LIFR conditions. /Fliehman
