... Air quality alert in effect until further notice...
An air quality alert has been issued by the following agencies:
Washington department of ecology in Spokane
Idaho department of environmental quality in Lewiston
Washington department of ecology in Yakima
Idaho department of environmental quality in Coeur D'Alene
Nez Perce tribe
Colville confederated tribes
kalispel Indian community
Coeur D'Alene tribe

Kootenai tribe of Idaho
Elevated concentrations of wildfire smoke from area fires
continues across eastern Washington and north Idaho. Additionally,
blowing dust is expected over much of the area on Saturday. All
areas east of the Cascades and into north Idaho can continue to
expect poor air quality into the weekend. There may be times and
locations where the air quality improves to the good category, but
this is not expected to persist.
Precautions to be taken for areas experiencing increased smoke and
reduced air quality include:
*everyone should avoid heavy work or exercise outdoors when the
air quality index reaches unhealthy levels.
*Older adults, small children, and those with respiratory
conditions or heart disease may be more sensitive to poor air
quality and should stay indoors and avoid heavy work when air
quality reaches unhealthy levels.
*Drink plenty of water. Staying hydrated helps dilute phlegm in
the respiratory tract, making it easier to cough out smoke
particles. Plan on coughing; it is nature's way of clearing your
lungs. Avoid caffeine products, sugary drinks and alcohol because
they have dehydrating effects.
*Stay cool when the weather is warm. Run your air conditioner to
recirculate air. Turn The Fan blower on manually so it
continuously filters the air in your home.
*If working outside, use a dust mask... n95 or n100. If a dusk mask
is not available, cover your nose and mouth with a damp
This air quality alert will be reevaluated by Monday at noon.

Area forecast discussion National Weather Service Spokane Washington 440 am PDT sun Aug 30 2015 Synopsis... a vigorous upper level disturbance will bring the inland northwest some much needed rain today. Area wildfires will have a good chance of a tenth to a quarter inch of rain. A cool, occasionally breezy and showery weather pattern is expected much of next week. && Discussion... Today and tonight...longwave trof hanging over a good portion of the western US allows a wet cold front to pass through it today. Pops remain high with such a scenario given the favorable long- wave trof placement and a somewhat well maintained moisture feed extending into it from the south/southwest overcoming the Lee side rain-shadow of the Cascades. 0-6km above ground level winds suggest storm motion to the northeast and east at about 25 to 35 mph today. This storm motion is fast enough to continue to note that flash flooding on area burn scars is not likely with today's rainfall. The -20 to -22 deg celsius 500mb cold pool contained in the trof is on the order of two Standard deviations on the cols side of what would be considered normal for this time of year, therefore a mention of thunder seems reasonable given the resulting instability of having this cold pool aloft. Forecast temperatures on the cool side of normal a given due to this trof and the resulting rainfall keeping the daytime high on the cold side while more effective radiational cooling is likely tonight under this trof. Robust winds from the southwest remain as well today that will decrease a bit tonight but likely not go calm given the dynamic nature of the the above scenario. /Pelatti Monday through Saturday...model agreement is pretty good between the latest GFS and ec runs with details and run to run consistency is very good regarding the overall concept of a persistently troffy pattern enveloping the region through the work week. A huge parent trough over western Canada will promote a series of disturbances brushing or enveloping the forecast area during the week. A well directed fetch of Pacific moisture will probably benefit from some isentropic and orographic enhancement into the Cascades and northern mountains on Monday. Tuesday may be a relatively dry day with a few degrees of warming before the next trough carves into the region with another cold front on or about Wednesday with the actual trough lingering over the region through Friday. This argues strongly for a period of cooler than normal temperatures...occasional periods of showers mostly on the mountains but with a few opportunities for basin precipitation as well. All this will be good news for the fire fighting efforts...but The Fly in the ointment will be the propensity for breezy and occasionally gusty conditions across the basin especially but also on the mid-slopes and ridges of the mountains surrounding the basin...which may hamper firefighting. Monday and especially Wednesday look like the breeziest days...with Wednesday in particular shaping up to be quite windy and gusty in the wake of an early day cold front passage. Way out on or about Saturday the models suggest a pattern shift back to a drying and warming weak ridge rebound over the region. /Fugazzi && Aviation... 12z tafs: the next 12 or so hours will potentially be the wettest as a wet frontal zone works its way through the area. Winds will be gusty but considerably lesser in comparison to yesterday. Smoke from area fires may impact taf sites again...especially kpuw and klws possibly resulting in IFR ceilings and visibilities. After 02z Monday the expectation is less wind and an end to precipitation and a return to mostly VFR conditions, with the exception of areas impacted by wildfire smoke. /Pelatti && Preliminary point temps/pops...
