Area Forecast Discussion
National Weather Service Boise ID
231 AM MDT TUE JUL 26 2016

.SHORT TERM...Today through Wednesday...A weak upper-level
shortwave will move through the area today, bringing isolated
showers and thunderstorms mainly to northeast Valley County this
afternoon and early evening. Otherwise, we will be dry through
Wednesday. After this shortwave moves by, our upper level flow
will turn from northwesterly to westerly. Very little cooling will
occur in the wake of this shortwave, so our highs today and
tomorrow will be much like Monday. This means near 100 in the
lower elevations and 70s and 80s in the mountains. Winds will be
typical for this time of year.

.LONG TERM...Wednesday night through Monday...Moderate westerly
flow aloft will continue dry weather through Friday with little
day to day temperature change. On Saturday monsoon moisture will
have its best chance to reach our CWA as flow aloft backs to more
southerly ahead of an upper trough from the Gulf of Alaska.
Forecast has a slight chance of thunderstorms for this. Saturday
also looks like the hottest day of the period. Cool front Saturday
night will bring temps down to normal Sunday. Incoming upper
trough will also shift the monsoon moisture to our east Sunday.
Monday looks sunny and breezy with normal temperatures.


.AVIATION...VFR with generally clear skies. Few cumulus over the
mountains 20Z-02Z. Smoke layers in the Lowman area, and patchy
smoke in the Snake River Valley until 18Z, including the KBOI and
KMUO areas. Surface winds variable 10 kts or less. Winds aloft
through 10k ft MSL west about 10 kts.
