Area Forecast Discussion
National Weather Service Spokane WA
1045 AM PDT MON AUG 31 2015

.SYNOPSIS...
Light rain will fall across the northern mountains today
with dry and breezy conditions for the remainder of the region.
A cold front brings a reinforcing shot of cooler air Wednesday
along with a chance for showers and gusty winds. Cooler and
showery weather pattern will linger over the region late week and
into the weekend.

.DISCUSSION...
Forecast update for today: The forecast for today continues to
bring good news for wildfire fighting efforts...especially in the
northern mountains. A corridor of rich mid and upper level
moisture will continue to stream into the region on the base of
the long-wave trough bringing a steady and light fall-like rain
from the northern Cascades to far north Idaho Panhandle. The
forcing associated with this activity is very weak thus...the
precipitation intensities will remain light with each six hours
bringing the potential for a few hundreths at a time. Closer to
the Highway 2 corridor, clouds will be present but precipitation
will largely be in the form of spotty sprinkles if any falls at
all. Dry conditions with sunbreaks will be found to the south
across the lower Columbia Basin and Central Idaho Panhandle.
Temperatures will be warmer today but still a handful degrees
below normal, especially north where light rain is falling. Winds
will become breezy again this afternoon but not near the speeds
what experienced Sunday afternoon. In general, winds of 10 to 15
mph will be possible across the open Basin and Okanogan Valley
with gusts near 20 mph. /sb

.AVIATION...
18Z TAFS: We are not seeing a lot of smoke coming out of the wildfires
near Lewiston and with persistent W/NW winds...we anticipate smoke will have
little impact the remainder of today.  Smoke models still bring some smoke
from near Pomeroy toward the KPUW-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 that fire.
Otherwise...mid and high clouds will slowly creep north with a small chance
for sprinkles through early afternoon.  Winds will remain breezy but much
lighter than Sunday.  /sb
