... Air stagnation advisory remains in effect until 10 am PST
* 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.
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.
... Record high temperatures for February 9th...
a record high temperature of 59 degrees was set at Lewiston ID Airport today.
This breaks the old record of 58 set in 1991. Records have been kept in
Lewiston since 1881.
A record high temperature of 56 degrees was set in Pullman WA today. This
breaks the old record of 52 set in 1987. Records have been kept in Pullman

Area forecast discussion National Weather Service Spokane Washington 404 PM PST Tuesday Feb 9 2016 Synopsis... strong high pressure will persist into Wednesday, with dry and mild conditions. A more progressive and unsettled pattern will return late this week, bringing a chance of light rain Thursday in the Cascades, then throughout the region Friday into the weekend. && Discussion... tonight through thursday: the ridge of high pressure will slowly weaken over the next couple of days as weak impulses of energy push onshore off of the eastern Pacific. Confidence is high that fog will redevelop across much of the same areas that had fog earlier this morning. This included much of the deeper valleys across the Idaho Panhandle, in the Cascades and northern mtn valleys. The question remains, and where models have not been much help as of late, is how much of the basin will see fog develop tonight. Surface temperatures are quite warm in the mid 50s for early February on the Palouse. This part of the region will likely remain clear with large dew point depressions in place. Winds at the surface will veer a bit across extreme eastern Washington from out of the northeast to out of the southeast. I think this will keep much of the northeastern portion of the basin from saturating as that drier air across the Palouse advects up into the Spokane West Plains. The best potential for new fog development by Wednesday morning will be across the southern portion of the upper Columbia Basin to western portions of the Moses Lake area. Low clouds are expected to hang around a bit longer across the northern mtn valleys on Wednesday. This will keep high temperatures for locations such as Omak, Republic, Colville, Metaline Falls and Bonners Ferry in the mid to high 30s or low 40s. Warmest temperatures will once again be across the Palouse and in the Lewiston-Clarkston Vly with highs a bit cooler than this afternoon, but still above normal in the upper 40s to low 50s. A weak system for Wednesday afternoon into Wednesday evening will increasing mid and high level clouds over the region. We will also see a chance for some precip in the Cascade mtns with possibly a few drops of rain possible over the northern mtns. A wetter warm front will begin to push in Thursday afternoon. This will result in a better chance for precip in the east slopes of the northern Cascades, as well as out over onto the Waterville Plateau and over into the Okanogan Highlands. Neither of these disturbances will bring much mixing, so the current air stagnation advisory remains valid and no changes will be made at this time. /Svh Thursday night through tuesday: the inland northwest transitions to a more active pattern, with several opportunities for precipitation. Look for a cool down into the weekend before temperatures rebound early next week. Thursday night into Friday a warm front will be draped across the northwest to northern cwa, while a weak mid- level shortwave skims by late Thursday night into Friday. This will bring a modest threat of precipitation to the Cascades through northern Panhandle, while a more transient threat comes to southeastern Washington and the central and lower Panhandle with the passing shortwave. Friday night into Saturday a cold front and stronger shortwave pushes through the region. This will revitalize the threat of precipitation across the region Friday night, before the steadier precipitation shifts into the mountains and leaves mainly hit-and-miss shower threat elsewhere Saturday. Snow levels should be high enough to support mainly valley rain and High Mountain snow. However we will have to keep an eye out for possible freezing rain in the overnight/morning hours especially near the sheltered valleys near the Lee of the Cascades. Winds are expected to increase for Saturday with the passing cold front, especially over the upper Columbia Basin through the Palouse/Spokane/c'da area and blues and over the mountains. Right now speeds are projected to be in the 10 to 20 mph range, with gusts to 30 mph. Precise numbers will continue to be fine-tuned. Then from Saturday night into Sunday night the next warm front starts to lifts in from the south with a subtropical moisture tap. This will expand the threat of precipitation across the region again, starting especially Sunday overnight. The threat will be lowest in the Lee of the Cascades and deeper Columbia Basin. Cooler air may initially allow for a rain/snow mix, with snow levels between 2.0-3.5kft Saturday night, before they rise again Sunday. Monday into Tuesday a trough pivots into the eastern Pacific and the flow over the inland northwest buckles and amplifies, shifting the warm front north and the precipitation threat into the mountains and northern counties. Models also suggest more breezy conditions going into Monday, but depending on the evolution of the warm front these speeds may be lower than forecast. The precipitation through the weekend into early next week, accompanied by some milder temperature, may lead to some significant rises on areas waterways due to rain and snow melts. The nwrfc indicates rises on most main-Stem rivers. At this time they are forecast to remain below any critical thresholds. However we will have to monitor these and any smaller streams /creek for rises and potential flooding concerns. I did raise highs slightly on Tuesday from the previous forecast but if the warm front is stronger and there is less cloud cover/precipitation those highs may need to be bumped up more. /J. Cote' && Aviation... 00z tafs: fog and stratus was observed for most of the mountain valleys this morning and along the Spokane/Columbia rivers...closer to water sources. The inversion will remain strong again tonight and fog/stratus will likely form in those areas again tonight. However the strong ridge of high pressure that has been over the region will shift east and Bend slightly overnight. This will allow upper level clouds to move into the region overnight as well...and this may mitigate somewhat the strong radiational cooling. In addition the surface flow will gradually come around to southerly through the evening and this should pile up the moisture for the northern valleys. With the exception of the eastern basin and the Palouse at least some fog and stratus will be possible for the taf sites. So klws/kpuw can expect VFR conditons through 00z. At the other taf sites current VFR conditions will likely drop down to MVFR cigs/vsby between 12-18z then bounce back to VFR with a thickening but high cloud deck.
