.SHORT TERM...(Tonight through Monday night)
Issued at 251 PM MDT Sun Sep 18 2016

High pressure will continue to dominate the weather pattern over
the forecast area in the short term with mainly clear skies
through the short term period. Heights will rise slightly through
Monday as the ridge of high pressure slowly builds to our east.
Seasonable overnight lows are expected tonight and Monday night
but with mostly sunny skies expect unseasonable high temperatures
on Monday.

.LONG TERM...(Tuesday through Sunday)
Issued at 251 PM MDT Sun Sep 18 2016

High clouds will spread north over the region on Tuesday as moist
southwest flow increases through the day. Isolated showers and
thunderstorms will develop by Tuesday afternoon and spread
northeast...increasing in coverage by Tuesday night. At the onset,
gusty outflow winds will be the main impact. However, locally
heavy rain will be possible with the stronger storms Tuesday night
into Wednesday, mainly over the southern half of the forecast
area. By late Wednesday, a strong storm system will be over the
Pacific northwest. This system will move into the Great Basin
region by Thursday and is forecasted to eject northeast through
Wyoming on Friday. Expect southwest flow to increase ahead of this
system late Wednesday into Thursday with showers and
thunderstorms increasing in coverage through Thursday night.
Colder air will move across the area by Friday morning lowering
snow levels to between 8000 and 9000 feet as precipitation
coverage becomes more confined to the higher elevations and the
northern portions of the forecast area late Friday into Saturday.
Drier northwest flow will return on Sunday. Temperatures are
expected to be seasonable through mid-week with much colder
temperatures expected by late in the week.
