Area Forecast Discussion
National Weather Service Spokane WA
1045 PM PDT SUN AUG 2 2015

.SYNOPSIS....
The ongoing drought combined with high heat and low humidity will
contribute to high fire danger throughout the Inland Northwest.
Temperatures on Monday should be a few degrees cooler with an
increase in clouds. Cooler temperatures and locally breezy winds
are expected mainly Monday through Wednesday following the arrival
of a cold front. Another threat of showers and thunderstorms
arrives next weekend.

&&

.DISCUSSION...
Update: Satellite shows a closed low off the central California
coast with south-southwest flow drawing up mid and high level
moisture. Radar shows some high based returns along the East
Slopes of the Cascades this evening...but most...if not all of
this should evaporate before reaching the ground given our very
dry low level air mass. Sky cover was increased a bit over North
Central Washington tonight to account for more mid level cloud
cover moving in.

The biggest update to the forecast was to add the Wenatchee,
Entiat, and Chelan areas to a fire weather watch for Monday and
Tuesday. Latest guidance, especially the NAM, is showing breezy
winds and low humidity both Monday and Tuesday in these areas.
Guidance shows Wednesday could be breezy as well but will hold off
for now for Wednesday given this is still several days out. This
is a good wind pattern through the Cascade gaps with the break
down of the hot ridge followed by several days of westerly flow as
a closed low over Central BC slowly drops south.  JW

.AVIATION...
06Z TAFS: Wildfire smoke will continue to reduce visibilities to
between 3-9 miles over much of the region...with greater
restrictions around Chelan. A weak weather disturbance passing
through tomorrow will result in mainly mid and high level
clouds...with a few sprinkles possibly reaching the surface.
