Area forecast discussion 
National Weather Service Spokane Washington
1130 am PDT Sat Jul 12 2014

Synopsis...

A prolonged heat wave will continue across the inland northwest
through this weekend and may linger well into next week. Mid to
upper 90s will be common, with triple digit heat in the Lewiston
area and portions of the Columbia Basin. There will be potential
for monsoonal moisture to invade the region early next week, with
some threat of thunder, but otherwise the forecast is dry.

Discussion...

A narrow band of high clouds moving slowly across eastern
Washington this afternoon may produce a couple hours of relief
from the heat. Places like Wenatchee, Moses Lake, Ritzville, and
Spokane may be a couple degrees cooler this afternoon than
previously though depending on how long the high clouds linger
this afternoon. Smoky conditions in the Wenatchee area may also
inhibit warming a bit. Even if temperatures don't hit 100 in
Wenatchee, highs will be a good dozen degrees above average.

Aviation...
18z tafs: hotter than normal temperatures will be the main weather
consideration this weekend into next week. The Mills canyon
wildfire north of Wenatchee continues to burn actively and has the
potential to contribute to poor visibility in the Chelan and
Wenatchee areas. Northwest drainage winds during the evening and
overnight hours will have the tendency to push smoke toward the
Wenatchee area as the night time inversion limits vertical mixing.
Visibility reductions under 4 miles will be possible depending of
fire behavior the next few days. /Gkoch
