Area forecast discussion
National Weather Service Spokane Washington
740 am PST Fri Jan 19 2018

Synopsis...
a slightly cooler but still very moist maritime air mass will
allow snow to return on area mountain passes and some minor
accumulations in the valleys as well this weekend. An active
weather pattern will continue into next week with light to
moderate snow possible Sunday into Monday and again Tuesday into
Wednesday.

Discussion...
morning update: the inland northwest will be in a break between systems
today with valley rain and mountain snow showers confined to
mainly the Cascade crest and Idaho Panhandle. For this morning the
forecast has been updated to add areas of fog to the Moses Lake,
Coulee City, and Wenatchee areas where web cams/surface
observations show areas of fog as of 7 am. Most of this is
shallow in nature and should burn off mid to late morning. Also
updated high temperatures for the northern valleys where several
places were already at forecast highs for the day. Although
stratus will limit temperature rises in these areas, so
temperatures were only increased 2-3 degrees. Jw

Aviation...
12z tafs: as a disturbance exits the region to the east this
morning a moist boundary layer air mass with light upslope winds
will promote IFR stratus ceilings at the Spokane area taf sites
which may partially break up into MVFR ceilings after 18z-20z.
Pockets of brief IFR conditions are possible in the deep basin and
klws area this morning as well but there will be a good chance of
improvement to VFR after sunrise today. The next disturbance will
spread -sn across the northern taf sites tonight with more low
MVFR or IFR ceilings and vis in -sn...with more intermittent
MVFR conditions possible at keat and klws and kpuw in -sn or
-rasn. /Mjf
