Area Forecast Discussion
National Weather Service Spokane WA
936 AM PST WED DEC 17 2014

.SYNOPSIS...
A more active weather pattern will develop through the week with
periods of light snow in the mountains...and rain or snow in the
valleys. Lower elevations from Interstate 90 south will see mainly
rain...while areas in the Cascades and near the Canadian border
will remain mainly snow. A much stronger weather system over the
weekend will usher in warmer temperatures with sharply rising snow
levels...as well as the potential for windy conditions.

&&

.DISCUSSION...
Quick update to increase pops and snow amounts for Wenatchee and
Waterville Plateau area as radar likly missing the stronger
returns as snow falls from lower cloud deck in that area. The wave
is weak and moving northeast. /Pelatti

.AVIATION...
18Z TAFS: Weak disturbances drifting northeast and over the
aviation over the next 24 hours keep the forecast somewhat
cluttered with mentions of both rain and snow at times which
produce IFR/LIFR ceilings and visibilities. Some fog will
occasionally impact locations as well. Precipitation still on the
light side with the higher amounts primarily near the East Slopes
of the North Cascades out to the Waterville Plateau and points to
the north/northeast. The KGEG area will be more MVFR most of the
time as the precipitation will be light and likely to be rain.
