Area Forecast Discussion
National Weather Service Spokane WA
937 AM PST Mon Dec 10 2018

.SYNOPSIS...
A few showers will continue mainly over the mountains today. A
stronger storm system arrives Tuesday, bringing the potential for
heavy mountain snow, light to moderate lowland snow, and locally
gusty winds. Unsettled weather will continue most of the week with
periods of mountain snow and a mix of rain and snow in the
valleys.

.DISCUSSION...
Bulk of the weather system that delivered this mornings
accumulating snowfall has moved east into Montana this morning.
The airmass remaining overhead of Eastern Washington and North
Idaho still remains cold and conditionally unstable and thus able
to support some off and on short lived shower activity today. With
this in mind pops and QPF remain on the light side for the rest of
today and a good part of tonight until the next storm system
starts to influence the East Slopes of the North Cascades and
northern locations as early as very late tonight/early Tuesday
morning. /Pelatti

.AVIATION...
18Z TAFs: Fog and low clouds the norm for much of the TAF interval
with the resulting low ceilings and visibilities in the IFR range
prevailing, especially at KGEG, KMWH, and KEAT. KPUW and KLWS may
show improvement and not have as intense fog and low clouds
tomorrow afternoon as low level southeast winds ahead of the next
incoming storm system may bring in drier air for a brief interval
but not far north enough to help KGEG,KMWH, or KCOE. /Pelatti
