Area forecast discussion 
National Weather Service Spokane Washington
1105 am PDT Sat Aug 29 2015

Synopsis...
a cold front will push through the inland northwest today and
bring high winds to the region. This will create a situation for
blowing dust with reduced visibility. There is the potential for
toppled trees and downed power lines as well. A cooler and
occasionally breezy regime with some shower activity will persist
through the next week.

Discussion...
a third update this morning to expand the dust Storm Warning
further north to include the Spokane area and the Waterville
Plateau. Current radar shows a gust front moving southwest to
northeast on the Spokane West Plains. Radar estimates gusts up to
40 mph approaching the Spokane area. Web cams, facebook and
twitter reports suggest visibility down to 1 mile or less due to
the blowing dust. Isolated spots of near zero visibility may be
possible. These conditions may result treacherous travel
conditions with the worst spots expected to be across the basin.
We have also received a spotter report of winds at 40 mph with
gusts to around 50 mph in Mansfield with visibility down to 1/4
mile. /Svh

Aviation...
18z tafs: the combination of smoke and blowing dust will
contribute to visibility problems that are difficult to forecast.
Look for frequent amendments through the early evening. Strong
west or southwest wind gusts are expected to Max by early
afternoon right behind the cold front. The poorest blowing dust
visibility will likely occur at Moses Lake, Spokane, and possibly
Pullman due to Dryland wheat fields upwind of these airports.
Visibility restrictions due to smoke in Lewiston should improve
through the day as wind disperses smoke. /Gkoch
