Severe Weather Alert Descriptions

 Air Stagnation Advisory  Statement as of 11:40 am PST on November 26, 2015

... Air stagnation advisory remains in effect from 9 PM this
evening 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.

Precautionary/preparedness actions...

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.

NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Spokane Washington 
358 am PST Friday Nov 27 2015 

chilly temperatures and clear skies are expected through at least 
Friday as strong high pressure builds over the Pacific northwest. 
Light winds and a strengthening inversion will increase the 
potential for air stagnation this weekend. We will also have the 
potential for areas of fog and low clouds over the weekend into 
early next week. The next chance of precipitation is expected next 
Wednesday with the arrival of a frontal system. 



Today through saturday: a dry and increasingly stable weather 
pattern will develop over the inland northwest today into 
Saturday. An air stagnation advisory is in effect through the 
weekend for the potential of air pollution build up given the weak 
winds and stable conditions. Mid-level subsidence will intensify 
our low level inversion over the next 36 to 48 hours making for a 
difficult temperature forecast. Elevations above the inversion 
will become increasingly mild with highs in the upper 30s to 40s 
while low elevations may not get out of the upper 20s and lower 
30s. Our surface winds will be light today into the weekend. 
Without the low level mixing the wind provides, temperatures may 
struggle to warm especially in The Lowlands with snow cover. MOS 
guidance does forecast cooler afternoon temperatures for most 
areas today compared to yesterday, but MOS has performed poorly 
the last couple of days suffering a cold bias of 2 to 5 degrees. 
With that in mind, the forecast for today and Saturday are a 
couple degrees warmer than the GFS MOS. Fog has been slow to 
develop early this morning. The evening sounding at Spokane was 
exceedingly dry in the low levels, so despite narrow 
temperature/dewpoint spreads it may take another night or two 
before our air mass moistens through local evaporative/sublimation 

Sunday: the fog and low cloud potential will be on the rise early 
Sunday morning and again Sunday night into Monday morning. Our 
current air mass is quite dry so the confidence level for fog 
development is rather low at this time. It is possible that mainly 
clear skies could persist into Sunday or possibly Monday. /Gkoch 

Monday through Thursday...models are in good agreement of an upper 
ridge over the area on Monday before the ridge moves east for 
Tuesday into Wednesday. With the ridge over the area on Monday 
a continuation of a stagnant weather pattern continues with low 
clouds and patchy fog expected for most valleys while the 
mountains should be mostly clear. As the ridge moves east on 
Tuesday a large low in the Gulf of Alaska will send multiple 
systems across the inland northwest Tuesday night through Thursday. 
Confidence is low in the details due to run to run inconsistencies 
with both the GFS and European model (ecmwf) solutions. Initially the air mass will 
be cold allowing for snow to fall. How quickly the region warms up 
will depend on the strength of incoming systems and how much low 
level mixing they provide to scrub out the cold air. It is also 
possible that a period of freezing rain could occur in some areas before 
the transition to rain. The northern valleys (especially the 
methow) will be the slowest to warm up and should see primarily 
snow during this period. Jw 


12z tafs: area web cameras and the satellite fog channel show 
patchy shallow fog in a few spots in the inland northwest this 
morning. Sandpoint, Bonners Ferry, and south of Moses Lake. Fog 
should dissipate by late morning giving way to sunny skies. Patchy 
fog will become a possibility for Lewiston and Moses Lake early 
Saturday morning and into the other taf sites (kgeg, ksff, keat, 
kpuw) by Sunday morning. /Gkoch
