Area Forecast Discussion
National Weather Service Boise ID
225 PM MDT SAT JUL 23 2016

.SHORT TERM...Tonight through Monday...The upper level trough
responsible for below normal temperatures today will move east
tonight and Sunday. Heights will increase over the area behind the
trough with warming of the atmosphere in a dry and zonal flow to
start the new week. Daytime highs will be near normal on Sunday
and then climb into the mid 90s to around 100 degrees in the lower
valleys on Monday. Light winds with little or no clouds across the
area, but there will be some smoke over the central mountains
around Lowman due to the Pioneer Fire.

.LONG TERM...Monday night through Thursday...Dry, mostly zonal flow
is expected through the period with temperatures 5-10 degrees above
normal (temperatures will reach the upper 90s to 100F in the lower
valleys). High pressure will progressively build over the four
corners region through the period, but will hold off in punching
north into the region for now.

Thursday night through Saturday...Thermal trough sits over the
region during this period with high pressure to our south. Models
are hinting at some monsoonal moisture possibly making its way up
north Saturday, but kept forecast dry for now based on low
confidence. Temperatures will remain 5-10 degrees above normal
during this time.


.AVIATION...VFR with mostly clear skies tonight through Sunday.
Expect smoke layers in the central Idaho Mountains northeast of
Idaho City, especially from the Lowman area east to Stanley.
Surface winds west-northwest 12 kts or less, except 10-20 kts
through the Snake River Plain KMUO and east, diminishing to 5-10 kts
before 06Z and remaining light through Sunday. Winds aloft through
10k ft msl west 10-20 kts, diminishing to 5-15 kts early Sunday.
