Area Forecast Discussion
National Weather Service Spokane WA
1021 AM PST SAT FEB 13 2016

.SYNOPSIS...
As an upper level disturbance exits the region, light showers will
decrease today leaving partial clearing and breezy winds. Areas of
fog and light winds will persist in the Cascade valleys. Unsettled
weather will return by this afternoon and through the rest of
weekend with valley rain, high mountain snow and gusty winds
expected. Temperatures will be quite mild, especially on Monday
with many locations seeing highs in the mid 50s to low 60s. Near
record high temperatures are possible.

.DISCUSSION...
Updated the forecast to allow the air stagnation advisory to
expire across the Columbia Basin. Enough southwest breezes are
expect to mix the lower atmosphere. Meanwhile, light winds and
stagnant conditions are expected to continue in the east slopes of
the northern Cascades and the Okanogan Valley through the weekend
and into early next week. Showers will continue to decrease across
north Idaho through midday, while clouds and light stratiform
precipitation will increase across the Cascades with the arrival
of the next weather system. Snow levels will remain high enough to
support rain and mountain snow. /rfox.

.AVIATION...
18Z TAFS: Low clouds and LIFR fog will bounce around in the KEAT.
Expect improvements through the afternoon and early evening with
the arrival of the light rain. But once the precipitation tapers
off overnight, anticipate the LIFR conditions to return under the
light winds. Meanwhile, occasional MVFR cigs will be a concern in
the KGEG-KCOE corridor and down to KPUW as moist southwest breezes
blow and enhance the low level upslope flow. Mountains will be
obscured across north Idaho and northeast Washington with light
showers. The band of rain will push across eastern Washington this
evening with several hours of rain at the TAF sites and local MVFR
cigs. As the precipitation tapers off by early Sunday morning
there is good confidence that MVFR and locally IFR cigs will
return especially for the eastern TAF sites.
