Area Forecast Discussion
National Weather Service Spokane WA
1028 AM PST Fri Nov 16 2018

.SYNOPSIS...
A cold front will drop through the region today and result in a
chance of rain and mountain snow showers this morning, with drying
from the north this afternoon. Temperatures will be cooler today
with locally breezy winds through north-south valleys. The cool
and dry weather will persist through the weekend into early next
week. The weather pattern may become more active as Thanksgiving
approaches.

.DISCUSSION...
Some parts are seeing the sun this morning as a drying cold front
continues to progress south into southeast Washington. Fog will
continue to break up this morning but there will be variable low
and middle clouds in the ID Panhandle, southeast Washington.
Expect stronger north winds to 15 mph down the Okanogan valley as
well as the northern Idaho Panhandle today into tonight along with
the dry, cool Canadian air.  Overall post frontal drying will
continue tonight into Saturday pretty much shutting off
precipitation until the middle of next week as high pressure
builds in from the west.

Strong high pressure over the region Sunday into next week will
likely produce stable and stagnant air conditions so an Air
Stagnation Advisory was issued starting Sunday to inform folks of
potential buildups of air particulates later this weekend going
into the upcoming holiday week. TC

.AVIATION...
12Z TAFs: Imroving conditions overall can be expected where fog
and stratus at KGEG, KSFF, KCOE have begun to lift after a recent
cold front passage bringing in drier air. After about 22Z most TAF
sites will be VFR however there will be some lingering stratus at
KPUW possibly producing MVFR CIGS as late as 08Z Saturday The
drier air previously mentioned will inhibit fog/stratus formation
tonight. There may be some fog at KSFF overnight but confidence is
low. Northerly winds will have the tendency to push any remaining
boundary layer moisture up against the Cascades and would effect
KEAT but confidence is low that significant clouds will impact the
site. TC
