Area Forecast Discussion
National Weather Service Spokane WA
1029 PM PDT MON 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 WA 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 VIS 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 ID. Some smoke is expected to
settle into the valleys of northern WA and northern panhandle of
Idaho. Breezy early evening winds will diminish overnight but will
become breezy again Tuesday afternoon. /EK
