Area Forecast Discussion
National Weather Service Spokane WA
1026 PM PST SAT NOV 22 2014

.SYNOPSIS...
Light rain and snow showers will pass through the southeast
tonight. Another round of rain and snow will arrive Sunday and
could make for slick conditions on area passes. The mountains
will receive another round of heavy snow Monday night into
Tuesday. A break in the active weather pattern will be possible
late in the week.

.DISCUSSION...
The shortwave weather disturbance that moved across the southeast
portion of the forecast area has pushed southeast of the region
late this evening. Web cams over the Camas Prairie indicate that
the snowfall over this area has stopped with only some lingering
showers expected for the rest of tonight. As such, the Winter
Weather Advisory has been allowed to expire over the Camas
Prairie, but will remain for the Central Panhandle Mtns with
Sunday`s weather system.

The next weather system off of the eastern Pacific is beginning to
move into western WA. This will result in snow picking up over the
Cascade Mountains early this morning. Light snow is then expected
to cross into the eastern half of the forecast area through the
morning hours. I did adjust snow levels up a little bit late in
the morning into the early afternoon. Strong southerly flow at low
levels should result in a change over from wet snow to rain by the
early afternoon across the basin into the Spokane and Coeur
d`Alene areas. With current temperatures hovering right around
freezing, this could occur fairly quickly as those southerly winds
pick up. /SVH

.AVIATION...
06Z TAFS: The boundary layer remains saturated through this
evening. Models continue to show a low stratus deck expanding from
Idaho into eastern WA. Confidence is not high on the timing of
when stratus will expand, but it is expected that KGEG, KSFF and
KPUW will see MVFR/IFR cigs developing after 09Z tonight. Another
wet system will bring widespread precipitation Sunday with a
strong possibility for several hours of snow at KGEG/KCOE/KSZT/KPUW
...snow is expected to begin to switch over to rain between 16-19z.
The precipitation will bring cig/vsby down to IFR and even LIFR at
times through 00z Sunday. /SVH
