Synopsis...
today will be another cloudy and chilly day in the inland
northwest. A frontal system will bring light snow to much of the
region on Sunday. Another front is expected on Monday, and it
should bring rain and mountain snow. Thursday and Friday also look
quite rainy next week.

Discussion...
a minor update has been issued to extend snow flurries around the
Spokane/Coeur D'Alene area and the central Panhandle mountains
through the morning hours. A deep and moist saturated boundary
layer extending up to around 5000-5500 feet combined with weak low
level upslope flow in these areas will allow snow flurries to
continue. This afternoon the weak low level upslope component will
come to an end although isolated flurries may continue over the
Idaho Panhandle due to the deep stratus layer. Jw

Aviation...
18z tafs: light snow or flurries should be on the decrease by 20z
around Spokane as low pressure system dives into Montana and
Wyoming by this afternoon. With the upper level ridge rebounding
this afternoon following the passage of the Montana system, look
for the stratus deck to persist through the taf period. The
inversion layer may lift and drop today and tonight causing
ceilings to rise and lower. In general, ceilings at most sites are
expected to be in the 800-2000 ft range. The next system will move
into the area on Sunday...with -sn expected to develop in the
Cascades late tonight or early Sunday morning with -sn or -rasn
possibly developing at the taf sites between 15-18z. Jw
