Area Forecast Discussion
National Weather Service Spokane WA
1035 PM PDT Wed Sep 25 2024

.SYNOPSIS...

Scattered showers and breezy winds will continue overnight. Temperatures
return to near normal by Thursday with another cold front passage
Friday. Above average temperatures return Saturday into early
next week, with Saturday the warmest day of the weekend. Some
freezing overnight lows are possible again heading into next week.

&&

.DISCUSSION...
Evening update: Weather conditions are calming down from earlier
today as the cooler, maritime air mass settles into the region.
With the higher humidity, lower wind speeds, and some
precipitaiton...blowing dust no longer poses a widespread risk and
we have ended the blowing dust advisory. Winds are also decreasing
but not calm by any means. Localized gusts 30-40 mph will remain
possible for the next few hours as the upper-level trough swings
inland and cold air advection continues. This will also keep a
threat for showers and a few lightning strikes into the overnight
hours.

&&

.AVIATION...
06Z TAFS: Cooler upper-level trough is tracking into the region
and will promote elevated winds through morning. Pullman has
recently decoupled and added wind shear but this comes with low
confidence and could see increasing surface winds overnight.
Bands of light showers will pass through with the best chance
coming across far SE WA, North Idaho, and the northern mountains.
A Puget sound convergence zone will also impact the Cascade crest
between Hwy 2 and I-90. Clouds with this activity will expand
into Wenatchee but any precip will mainly be confined to
Leavenworth to Stevens Pass. Otherwise, majority of the region
will experience VFR skies with lighter winds on Thursday..


FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Moderate
confidence in VFR conditions for much of the region. The one
uncertainty will be a small shield of MVFR ceilings developing
between Pullman and Spokane. HREF gives this a 20% of occurring.
