... Air stagnation advisory in effect from 9 PM Thursday to noon
The National Weather Service in Spokane has issued an air
stagnation advisory... which is in effect from 9 PM Thursday to
noon PST Monday.
* Air quality... poor ventilation will result in a build up of
pollutants near the surface. Mountain valleys will be especially
susceptible to stagnant air and pollution build up. Light
northeasterly winds across the basin will also tend to push
pollutants up against the east slopes of the northern Cascades
between Thursday and Saturday. These winds will become calm by
Sunday with a greater risk of pollutant build up over much of
the region by this time.
* Timing... Thursday night through Monday morning.
* Impacts... prolonged periods of stagnant air can hold fine
particulates close to the ground and degrade air quality.
An air stagnation advisory indicates that due to limited movement
of an air mass across the advisory area... pollution has the
potential to increase to dangerous levels. Persons with
respiratory illness should follow their physicians advice for
dealing with high levels of air pollution.
During periods of stagnant air... state air quality agencies
highly recommended that no outdoor burning occur and that
residential wood burning devices be limited as much as possible.
According to state air quality agencies... prolonged periods of
stagnant air can hold pollutants close to the ground... where
people live and breathe.

Area forecast discussion National Weather Service Spokane Washington 902 PM PST Wednesday Nov 25 2015 Synopsis... winds will decrease into Thanksgiving day, but temperatures will be cold, with most areas only reaching the mid 20s to low 30s. It will remain dry and chilly, with an increasing chance of fog and low clouds starting this weekend. The next chance of precipitation arrives by the middle of next week. && Discussion... quick update this evening to lower temperatures in some of the sheltered areas such as Republic and Winchester which can expect overnight lows in the single digits. Winds remain breezy in the Okanogan Valley with Omak still blowing around 20 mph. Latest lamp guidance suggest winds will remain 15-20 mph while other MOS is closer to 10 mph. Either way, temperatures will struggle to dip into the mid teens unless winds were to fall below 10 mph so have warmed overnight lows closer to 20f. Surface analysis indicates a 1040 mb high pressure cell just north of the border which is helping to fuel these light winds. Needless to say, its going to be cold night across the region with readings the coolest so far this season. Light winds will make for wind chills in the single digits. The good news is the air mass is extremely dry so fog should not be a concern and a lot of the moisture on the roads has evaporated so icy spots will mainly be reserved to those locally known shady areas. /Sb && Aviation... 06z tafs: expect VFR conditions for all sites, with a light north to NE wind generally from 5-15 mph. Slightly stronger speeds in the range of 10-15 mph will be found locally near Omak and Sandpoint. /Sb && Preliminary point temps/pops...
