Area forecast discussion 
National Weather Service Spokane Washington 
1029 PM PDT Monday Aug 31 2015 


Synopsis... 
light rain in the northern mountains will slowly creep north 
tonight. Tuesday will feature dry and breezy conditions. A weak 
cold front brings a reinforcing shot of cooler air Wednesday 
along with a chance for showers and gusty winds. A cooler and 
showery weather pattern will linger over the region late week and 
into the weekend. 




&& 


Discussion... 
light rain has ended across the northern mountains this evening 
and radar mosaic is showing lighter returns along the Cascade 
crest. Water vapor satellite imagery shows a weak impulse tracking 
across the region and there is enough resident moisture to wring 
out a few light showers across the northern mountains overnight 
but probably not more than a few hundredths of an inch will fall. 
Winds in the more sheltered valleys have quieted down tonight but 
the ridgetops and exposed areas like the Waterville Plateau remain 
a bit breezy. I have not seen any reduction in visibility in smoke 
from area wildfires but smoke models continue to bring some into 
the northernmost valleys and also into the Lewis-Clark Valley 
overnight. The Lewiston area is vulnerable from fires to the 
southwest in NE Oregon and also from the southeast from central 
Idaho wildfires. This is the only taf site that shows enough 
confidence to place a visibility restriction in the aviation 
forecast. All in all, a rather quiet night weatherwise. /Kelch

Aviation... 
06z tafs: areas of light rain will continue across the Cascade 
crest and far northern Washington tonight but will not impact any taf 
site. Smoke models still bring some smoke from near Pomeroy toward 
the klws corridor and if this is the case, nocturnal inversions 
could result in some reductions of visible until morning. Confidence 
is low due to uncertainty with burning behavior of the NE Oregon 
wildfire. Klws is also vulnerable to smoke from the southeast 
where fires are burning in central Idaho. Some smoke is expected to 
settle into the valleys of northern Washington and northern Panhandle of 
Idaho. Breezy early evening winds will diminish overnight but will 
become breezy again Tuesday afternoon. /Ek
