Area Forecast Discussion
National Weather Service Spokane WA
1053 PM PDT Sat Nov 6 2021

.SYNOPSIS...
Several weak systems will bring the chance of rain or snow to the
region through the weekend and into Monday. Cascade passes may 
receive several inches of snow over the weekend. A potentially 
stronger storm could impact the area on Tuesday with snow in the 
mountains and a mix of rain and snow in the valleys. By the end of
the week, there is a decent chance we could be looking at warming
temperatures with a strong ridge forecast to build over the 
region. This should push the precipitation chances toward the 
Canadian border or northward.

.DISCUSSION...
Evening update: the forecast generally looks on track, with the
area under a broader upper trough and disturbances pivoting around
it. The main precipitation chances tonight are expected to remain
around the mountains tonight and early in the morning. The main
possible divergence from the ongoing forecast is a weak impulse
coming around the trough, tracking through the basin eastward,
bringing with some limited risk for flurries or a sprinkles, maybe
even a stray shower. The risk will be a bit better toward the
WA/ID border, in the upslope flow, with the addition of some
lower clouds. Otherwise the next broader precipitation potential
comes in later Sunday into Sunday night, with the next wave.

.AVIATION... 
06Z TAF: Moist upslope westerly flow into the Panhandle will 
result in showers continuing into the overnight hours. Snow levels
will drop through the night with a dusting of snow possible for 
Sandpoint and Bonners Ferry. A moist boundary layer is expected to
result in low stratus over northeast Washington and into the 
Panhandle for Sunday morning with marginal VFR conditions 
possible. Some light flurries or sprinkles, maybe a stray snow
shower, may come out of the stratus but confidence is low. Cloud 
bases are expected to lift to between 4-6 kft agl in the 
afternoon, before the next precipitation potential comes in after 
about 00-02Z including possible -shra/-shsn. /Cote'
