.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 237 PM MST Sat Nov 8 2025

An amplified ridge of high pressure over the West is producing
another day of mild fall weather conditions across the West Slope.
A few clouds left over from last night`s passing wave have
dissipated and blues skies are in control. Temperatures have nudged
up a degree or two today, despite the stacked northwesterly flow
aloft evident on this morning`s Grand Junction upper air sounding.
Clear skies and light winds will welcome crisp and cool conditions
Sunday morning, with cold, elevated basins seeing the brunt of cold
air. The lower valleys will actually be a bit warmer Sunday morning,
especially closer to the center of the high in the Great Basin.

Additional subsidence and clear skies Sunday afternoon will find
most of the region 5 to 10 degrees above average. Light winds and
plenty of sunshine will make for a pleasant close to the weekend.
Sunday night will return a carbon copy forecast of tonight to kick
off the work week.

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 237 PM MST Sat Nov 8 2025

It`s high pressure ahead throughout the early portion of the long-
term period with high pressure dominating the western CONUS. Mostly
clear skies and afternoon temperatures 5-15 degrees above normal are
anticipated throughout much of next week as a result.

A shift in pattern arrives towards the end of the week though as
models suggest strong moisture will begin penetrating the
Intermountain West ahead of a high-amplitude trough. This system`s
timing is highly variable still per cluster analysis, with impacts
arriving anywhere between early Thursday afternoon to late Friday
morning. PWAT`s are uncertain too, though the consensus appears that
at its peak, PWAT anomalies will exceed 200%, so whenever it does
arrive, widespread precipitation should be possible. Long story
short, it remains tough to gauge the nature of this system, and we
will continue to monitor it over the coming days as we await model
guidance to come into better agreement.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/...
Issued at 433 PM MST Sat Nov 8 2025

A few high clouds will move overhead this evening and tonight
but will not pose any aviation concerns. A few locales are
seeing gusts of around 20kts but these will die down shortly
giving way to a calm night. High pressure continues tomorrow
onwards.
