Area Forecast Discussion
National Weather Service Spokane WA
950 AM PST Thu Feb 23 2017

.SYNOPSIS...
A cooler and continued unsettled pattern will descend over the
region for remainder of the week. The main precipitation threat
will be mainly mountain based snow showers, but a stronger system
on Sunday may bring minor snow accumulations to the valleys and
basin. Temperatures will be cooler than normal for this time of
year with overnight lows in the teens and 20s and daytime highs
only in the mid 30s or so.

.DISCUSSION...
Rest of today...No significant changes expected to the inherited
forecast this morning. Satellite indicates most of the region is
basking under late winter sunshine this morning...except fro the
eastern basin where a shallow but stubborn reach of fog and low
clouds is slowly eroding...and the Idaho Panhandle mountains
which are still under the influence of an exiting weather system
with orographically generated clouds and possibly a few flurries.
For the rest of the day a general improvement to partly to mostly
sunny conditions is expected...but with cooler than normal
temperatures with many locations struggling to break into the low
to mid 30s. /Fugazzi

.AVIATION...
18Z TAFs: A shallow layer of fog and low clouds over the eastern
Columbia Basin this morning is slowly eroding from the north and
west. General improvement between 18Z and 20Z to VFR conditions
is expected at the KGEG area TAF sites and KPUW. However...surface
conditions tonight will be similar to this morning so an expected
return of low clouds and fog has been added to the end of the TAF
period for these locations. KLWS...KEAT and KMWH are outside of
this eroding fog and stratus field and will remain VFR through
today. As a surface low pressure develops off the Pacific coast
overnight tonight a field of upslope low VFR ceilings may develop
over KEAT and KMWH after 12Z Friday. /MJF
