Area forecast discussion 
National Weather Service Spokane Washington
1133 am PDT Monday Jul 28 2014

Synopsis...
hot temperatures and dry weather will continue through midweek.
Thunderstorms chances will increase during the latter portion of
the work week as monsoonal moisture overspreads the inland
northwest.



&&

Discussion...
rest of today...strong ridge continues to build over the inland
northwest today. This will result in hot temperatures for all
locations with triple digit heat expected across portions of the
lc valley...lower Columbia Basin...and Okanogan Valley. The
warmest temperatures will generally coincide with the heat
advisory which was issued earlier for the lower Columbia Basin and
lc valley. The heat will also feature low relative humidity values
for all locations. Fortunately, we only foresee light winds
across the region for this afternoon.

Aside from these issues...there is a weak disturbance pushing
through southeast Washington at this time. There is a pool of mid-level
moisture and a little instability associated with said feature.
According to radar and local observations...some of this was
manifesting itself as sprinkles. Based on extrapolation and fine
temporal resolution model data, we would expect most of this to
shift into Montana and south of the Camas Prairie by 2 PM.

Aviation...
18z tafs: high pressure ridge will deliver generally clear skies
and VFR conditions to all sites through 18z Tue. Main weather will
be associated with a weak disturbance tracking northeast through
southeast Washington and the southern Idaho Panhandle. This could bring some
temporary mid level cigs to puw and lws and perhaps a sprinkle
through 21z...but most of that will occur east of these sites. Fx
