Area forecast discussion, Aug 28, 1:30 PM PDT, 30 minutes before

Area Forecast Discussion
National Weather Service Boise ID
230 PM MDT SUN AUG 28 2016

.SHORT TERM...No significant forecast changes through Monday, but
Tuesday now looks as hot as Monday even under increasing clouds.
About 5 degrees warmer Monday as flow aloft backs from westerly to
southwesterly.  Upper trough in the northeast Pacific will rotate a
short wave trough through eastern Oregon Tuesday with a slight
chance of thunderstorms there and also in the central Idaho
mountains Tuesday afternoon.  Moderate southwesterly winds in
eastern Oregon Monday afternoon, and again in southern Harney and
Malheur Counties Tuesday afternoon.  Continued smoky near the Rail
fire in Baker County, the Pioneer fire near Lowman, ID, and the
Rough fire northeast of the Pioneer fire.

.LONG TERM...Tuesday night through Sunday...An upper level trough
sitting off the British Columbia coast will slowly track its way
southeast during this time period. Southwest winds out ahead will
help keep temperatures slightly above normal, but by Thursday
temperatures are forecast to start dropping once more. Unsettled
pattern persists for the rest of the period, but models are trending
this low to stay farther north which will limit the showers and
afternoon thunderstorms to farther north than previously expected.
By Sunday another trough starts to make its way southward keeping
temperatures below normal and chances of showers and afternoon
thunderstorms.

&&

.AVIATION...VFR with areas of MVFR/IFR conditions in and around
wildfires. Increased mid-upper level clouds moving in this
afternoon. Surface winds, variable 10 kts or less. Winds aloft to
10k feet MSL, west-southwest 10-15 kts, then 15-30 kts Monday
