Area Forecast Discussion
National Weather Service Spokane WA
753 AM 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 Monday. Temperatures for Tuesday through Friday will likely be
at or below average.

&&

.DISCUSSION...

Rest of today: We increased the areal coverage of the smoke for
the western part of the Columbia Basin...and especially the Lake
Chelan area. We also included significantly reduced vsbys for
these same areas. One-half mile vsby due to smoke is likely for
the Lake Chelan region as well. Vsbys down to as low as one mile
for the Waterville Plateau and Moses Lake/Ephrata areas look
likely as well. We`ll be closely watching winds for later today
for the Cascade gaps (Wenatchee region). Some of the hi- res
model data actually supports light and variable winds through late
afternoon. bz

.AVIATION...
12Z TAFS: VFR conditions can be expected over the TAF sites for
the next 24 hours. Expect some smoke aloft with the best chance
for reduced surface visibilities around sunrise when the inversion
is the strongest...especially near Lake Chelan and in the Okanogan
valley. High pressure across the region means only light diurnal
winds through the day. Some local mustiness is possible during
the afternoon. Gap winds will increase winds at KEAT after 00z.
