Area Forecast Discussion
National Weather Service Spokane WA
1028 PM PDT SAT AUG 1 2015

.SYNOPSIS....
Expect a very hot weekend with afternoon temperatures in the mid
90s to near 105. The ongoing drought combined with high heat and
low humidity will raise concerns for wildfires the next several
days. A cold front will bring temperatures back closer to average
on Tuesday. Temperatures Wednesday through Friday will likely be
at or below average.

&&

.DISCUSSION...
Update: Overall a quiet night in place with an upper ridge
persisting over the region. Main story is the area wildfires which
has contributed quite a smoke to several areas across Central and
Eastern Washington into North Idaho. The biggest
fire...Wolverine...near Lake Chelan has been putting up the
largest amount of smoke while other fires near Ione and earlier
near Sprague have also been a contributor. With the fires near
Lake Chelan and Ione still burning active as of 9 pm per evidence
from satellite and/or radar with an inversion setting in...there
will likely be quite a bit of smoke around the area tonight.
Forecast has been updated to increase coverage of smoke
tonight...as well as around the Moses Lake, Ephrata, and southern
Okanogan Valley areas for Sunday. JW

.AVIATION...
06Z TAFS: Smoke will continue to be the main aviation concern
through Sunday. The smoke will be most prevalent in portions of
central Washington near the Wolverine Fire. Lower level smoke
will increase around Chelan tonight, with the BlueSky model
keeping this smoke east of KEAT again...but impacting KMWH
overnight into Sunday morning. Confidence is not high concerning
timing of MVFR visibility as KMWH...so went with a compromise
between timing of BlueSky model and persistance. Some improvement
is expected Sunday afternoon at KMWH as surface winds switch from
N-NW to SW. JW
