Area Forecast Discussion
National Weather Service Spokane WA
1248 PM PST Fri Dec 9 2016

.SYNOPSIS...
Periods of light snow will continue through the weekend and into
early next week. Brisk dry north winds are expected Monday down
the Okanogan Valley the will spread out over the western basin.
Temperatures will become very cold by Tuesday that will continue
through next week. Many areas will see overnight temperatures fall
into the single digits with some locations seeing temperatures
below zero for early to mid week.

&&

.DISCUSSION...
Snow continues to increase on radar and spread across the region.
Have received reports of freezing drizzle in the Basin and
probably pockets of freezing rain in the lower Palouse. This
ontop of the general increase of snow overnight into Saturday,
prompted the issuance of winter wx advisories into tonight. /rfox.

.AVIATION...
18Z TAFS: Radar shows the light snow will gradually increase
especially for the eastern TAF sites for the afternoon and
especially overnight as the warm front enhances over the region. A
band of MVFR cigs and light snow will span across much of the
region. As snow intensities increase, anticipate cigs to lower to
IFR and occasional MVFR vsbsy. There some indication of a brief
period of FZRA late tonight into early Sat morning for the
KPUW/KLWS area. Confidence is low on this, although a rain or
sleet mix is possible. Think the depth of the cold air is
sufficient to keep it mostly as snow. Anticipate improving
cig/vsbys after 15z from south to north as the warm front pushes
north. /rfox.
