312 AM MDT MON SEP 26 2016

.SHORT TERM...Today through Tuesday...No significant change in the
weather through Tuesday with an Upper level ridge over the
Intermountain West. Thus, dry conditions with light winds and
Temperatures about 10 degrees above normal is expected. The ridge
does flatten (weaken) on Tuesday as a shortwave moves across
Western Canada but this should have little effect on the forecast
area in general.

.LONG TERM...Tuesday night through Monday...Warm and dry under an
upper level ridge through Wednesday, with afternoon temperatures at
about 10 degrees above the seasonal norm. As the ridge shifts east
and out of the region Thursday, will see increasing cloud cover from
the south as a moisture plume heads north out of the Four-Corners
Region. This moisture plume will bring a slight chance of showers to
the mountains north of the Snake River Plain Friday before being
kicked east by an incoming upper level trough. This trough will
bring unsettled weather to the region through the extended. Best
chances for precipitation come Friday as the trough`s associated
cold front passes through the region and again on Monday as a
shortwave transitions through. Temperatures will decrease with the
incoming trough, bringing the region to about 10 degrees below
normal under a northwesterly flow by the end of the period.
