 Air Stagnation Advisory  Statement as of 2:36 PM PST on February 8, 2016


... Air stagnation advisory in effect until 10 am PST Saturday...

The National Weather Service in Spokane has issued an air
stagnation advisory... which is in effect until 10 am PST
Saturday.

* Air quality... light east winds and a temperature inversion will
heighten the potential for elevated pollution levels in central
Washington and northeast Washington tonight through Saturday
morning. Weak weather disturbances will pass through the area
starting Wednesday night and may slightly improve the
situation... however a stronger cold front passage Saturday is
expected to end the stagnant conditions which is why the air
stagnation advisory is in effect until 10 am PST Saturday.

* Impacts... burn bans may be in effect for your area. Please
consult your state or tribal authorities before burning.

* Locations... a few communities included in the air stagnation
advisory are... Ritzville... Moses Lake... Grand
Coulee... Colville... Omak... Winthrop... Wenatchee... and
Leavenworth.

Precautionary/preparedness actions...

An air stagnation advisory indicates that due to limited movement
of an airmass 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.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
411 PM PST Monday Feb 8 2016 


Synopsis... 
strong high pressure will persist into Wednesday. Dry and mild 
conditions are expected for the first half of the week. A more 
progressive and unsettled pattern will return late this week 
bringing a chance of light rain Thursday in the Cascades and over 
the rest of the region Friday through the weekend. 


&& 


Discussion... 
tonight and tuesday: strong high pressure will continue to build 
in over the region. The ridge axis will shift further more into 
the interior over the next 24 hours. This will shunt higher cirrus 
clouds spilling over the ridge further north of the region with 
clear skies becoming more prevalent overnight. The tricky part of 
the forecast will be where will the fog form and how long will it 
linger into Tuesday. The thought process is that since winds will 
be weak from the east that the best potential for fog in the basin 
will be across the wester portions (i.E. Generally west of 
ritzville). The northern valleys over to the east slopes of the 
northern Cascades are also expected to see fog form overnight. 
Warm temperatures this afternoon (into the low to mid 50s) and 
light downsloping winds across the southeast portion of the region 
should keep these areas fog free. How much of these clouds 
dissipate from the south will play a big role as far as how much 
the northern and western fringe of the basin warms up tomorrow. 
The forecast reflects the idea that much of the low clouds will 
erode across the basin with highs warming up into the upper 40s 
and low 50s. Temperatures are expected to be warmest across the 
Palouse, into the central Panhandle mtns, Lewiston-Clarkston Vly 
and on the Camas Prairie where record high temperatures in the mid 
to upper 50s will be possible. /Svh 


Tuesday night through Monday...ridge of high pressure continues to 
influence the region in some shape or form until a vigorous wet 
cold front passage occurs Saturday. The remaining weak dirty 
ridging left in place is such that the flow remains active as 
moisture and disturbances run through the top of it and through 
eastern Washington and northern Idaho. What this means is stagnant 
weather conditions will continue with low level easterly flow 
banking various intensities of low clouds and fog into The 
Lowlands and valleys with the exceptions of the Spokane area, 
Palouse, and just about all of north Idaho as the easterly winds 
work to keep those exception areas from being stagnant. 
Backtracking a bit the upper level ridge axis is over north Idaho 
for most of this time interval between Tuesday night and Friday 
night and some gradual de-amplification of the ridge occurs as 
early as Wednesday night and this may allow for very light 
precipitation to fall, mostly in the form of very brief and 
infrequent light rain or sprinkles as the warm inversion remains 
in place. Mid slope elevations will be quite warm as the 
subsidence inversion from this ridge influences those elevations 
while at the very bottom of the inversion some locations will not 
mix well, if at all, and stay cold and cloudy. /Pelatti 


&& 


Aviation... 
00z tafs: a strong ridge of high pressure will remain over the 
forecast area through the week with much drier air moving into the 
region. For tonight through Tuesday clearing skies and light 
northeast to southeast winds will allow good radiational cooling 
and the development of strong morning inversions. This in turn 
typically will result in the formation of fog and stratus. The 
drier air and easterly gradient will keep that in check somewhat. 
For kgeg/ksff fog and stratus will likely form late tonight and 
linger through the morning. So VFR/MVFR conditions will drop to 
IFR/LIFR cigs/vsby 14z-20z before clearing in the afternoon. 
Confidence is only low to moderate for LIFR conditions. Kcoe- 
kpuw-klws will remain VFR...however some ground fog may form early 
in the morning near kcoe. The easterly gradient will allow the 
moisture to pile up along the east slopes of the Cascades. The 
best chance for IFR/LIFR vsby/cigs will be at kmwh- keat between 
08-18z but again confidence is only moderate with the amount of 
dry air in place. Tobin
