Area Forecast Discussion
National Weather Service Spokane WA
937 PM PST Sun Dec 4 2016

.SYNOPSIS...
Much colder temperatures will move into the region tonight ahead
of the next weather system set to arrive on Monday. Light snow is
forecast for the Columbia Basin, Palouse, and southern Idaho
Panhandle for Monday afternoon into Monday night. More snow is
possible Thursday into Friday for most areas.

&&

.DISCUSSION...
A cold upper trough will settle into the region tonight bringing
cold temperatures with lows mostly in the upper teens to mid 20s.
Drier air coming in behind the cold front passage earlier today
will continue to spread east from Central and Eastern Washington
into the Idaho Panhandle. Thus while a few snow showers linger
in the mountains of the Idaho Panhandle this evening expect activity
to continue to decrease. The winter weather advisory was allowed
to expire at 7 pm. A few adjustments to sky cover were also made
based on latest satellite trends.  JW

.AVIATION...
06Z TAFS: Clearing skies as drier air moves into the region will
result in VFR conditions at the TAF sites tonight. Monday morning
boundary layer winds shift to a light upslope south direction
towards KGEG/KSFF/KCOE with a chance of IFR or MVFR stratus
development. The NAM is most aggressive with this idea but with
the amount of dry air currently moving in leaning towards the less
pessimistic GFS solution. The next system then spreads -SN into
the region...beginning near 21-22z at KEAT/KMWH before reaching
KPUW/KLWS/KGEG between 03-05z. MVFR conditions are expected to
develop due to a combination of boundary layer moistening and
visibility restriction from snow.  JW
