Area Forecast Discussion
National Weather Service Spokane WA
353 PM PDT Sat Oct 1 2022

.SYNOPSIS....
Some low clouds and fog may develop over portions of Eastern
Washington and North Idaho overnight, otherwise high pressure will
gradually work its way in allowing for warmer and dry weather
lingering on into much of next week.

&&

.DISCUSSION...
Tonight through Saturday: A ridge will be in place over the
Pacific Coast and bring a warm, quiet start to October. Models are
in good agreement of the pattern. The high pressure will keep the
the skies generally clear and allow for decent daytime heating. It
will cause highs for the period to run around 10 degrees warmer
than normals for this time of year.

Most of the region will be under mostly clear benign weather
conditions. The weather impacts for the period are expected to be
localized morning fog for northern valleys and wildfire smoke in
the Cascade Valleys. The clear skies will allow for the optimal
radiational cooling overnight. With low dewpoint depressions
shallow fog will develop in the northern valleys during the early
morning hours. Smoke is expected to settle in the Cascade Valleys
as there is very little wind movement with high pressure in place.

Temperatures will have very little variation from day to day.
Highs will be in the 70s to low 80s. Lows will be in the 40s to
low 50s.

Models begin to breakdown the ridge over next weekend with as a
cold front will press in from the North. It will not bring much in
the way of precip if any. The best chance for precip be in over
the Idaho Panhandle. /JDC

.AVIATION...
00Z TAFS: VFR conditions expected through the TAF period. Winds
will be light under clear skies. Shallow fog is again expected to
impact northern valleys and GEG-SFF-COE sites. Low level stratus
is likely for these areas. With increase in drier air, it is not
expected to be as widespread as Saturday morning. It should
diminish by mid morning and VFR conditions through the rest of
Sunday. /JDC
