Area forecast discussion 
National Weather Service Spokane Washington
956 PM PST Thursday Jan 29 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...
dense fog advisories have been issued for a majority of eastern Washington
and nrn Idaho including most valleys in Washington stretching from
Pend Oreille to Whitman counties and in Idaho, the us95 corridor.
Fog continues to thicken this evening under clear skies. I
anticipate with light winds and clear skies persisting overnight,
most locations will be dealing with visibilities at or below a quarter
mile by the Friday morning commute. In addition, temperatures have
dipped into the mid to upper 20s which is likely to produce slick
roadways.

Aviation...
06z tafs: light winds and clear skies aloft will continue to bring
widespread restrictions from fog and stratus through the next 24
hours. Freezing fog will impact kgeg/ksff/kcoe/kpuw and possibly
klws while keat/kmwh will largely contend with stratus. Minor
improvements possible Friday afternoon with the highest
probabilities btwn klws/kpuw but the overall chances appear slim
in comparison to Thursday afternoon. /Sb
