Area Forecast Discussion

652 PM PST Fri Feb 22 2019

.SYNOPSIS...
Snow will move from extreme eastern Washington into the Idaho
Panhandle this evening. A moist frontal system is expected to
stall over Oregon and central Idaho saturday night Sunday before
moving back to the north Sunday night and Monday. This will have
the potential to produce moderate to heavy snow as far north as
Highway 2. Temperatures will remain on the cool side of normal the
next 6 to ten days with mountain snow at times.

.DISCUSSION...
Radar shows a well-defined band of snow from Bonners Ferry down to
Walla Walla. The back edge of this band is nearing Reardan. Timing
this would put the end of the snow to the WA/ID border by about
800pm, moving out of the Panhandle by midnight. Fog and low clouds
are expected to develop in the wake of this snow and persist
through much of Saturday with some mountain snow showers.  RJ

.AVIATION...
00Z TAFS: A weak cold front will move through the region this
evening, bringing light snow to KGEG/KSFF/KCOE/KPUW airports. Cigs
and visibilities should generally remain MVFR with this light
snow, which should end by about 07Z. Behind this front, the winds
will become southwesterly, which should cause low stratus to form
for KGEG, KSFF and KCOE, which will likely persist through
Saturday. KLWS should remain VFR through the next 24 hours, but
could have some brief MVFR cigs this evening. KMWH and KEAT won`t
see much if any snow. But their challenge is the formation of fog
behind the front. Not confident enough to put fog in KMWH. KEAT
already has some fog with an MVFR cig, and computer guidance
suggests it will gradually lower overnight.  RJ
