Area Forecast Discussion
National Weather Service Spokane WA
1151 AM PST SUN NOV 23 2014

.SYNOPSIS...
The mountains will receive another round of accumulating snow
this afternoon and evening. Most of the lower elevations will
experience light rain, but some wet snow is possible in the far
northern valleys. Monday will be a relatively quiet and chilly
day. More rain and heavy mountain snow is expected Monday night
into Tuesday. A breezy and wet weather pattern will persist for
much of the week with the mountains receiving several rounds of
snow.

.DISCUSSION...
Updated the forecast to adjust temperatures and precipitation
coverage across the region. Temperatures warming with the
rain/snow line in the valleys stretching from Twisp, Republic, to
Colville to Bonners Ferry. Satellite shows the dry slot moving
across the northern Cascades, and should see the snow taper off in
the Methow valley this afternoon. Radar activity has enhanced over
northeast Washington and north Idaho and should continue through
mid afternoon. /rfox.

.AVIATION...
18Z TAFS: Radar trends and 15z HRRR model show most of the shower
activity today will develop just east of KGEG/KSFF with light
rain and snow showers spanning from extreme northeast Washington,
north Idaho. Strong low level warm advection has raised both temps
and dewpoints, making the precipitation type mainly rain at the
TAF sites. Airports north of the metro like Bonners Ferry and
Colville may see a slushy runway accumulations up to an inch will
be possible. Gusty westerly winds will develop from KEAT to KMWH
this afternoon and evening. Dry/downslope advection from the
west/northwest this evening should disperse stratus in the
evening, but fog and low stratus may crop up toward Monday
morning from KPUW to KGEG and KSFF. /rfox
