KEY MESSAGES, Issued 853 PM MST Thu Nov 5 2026

- Modestly strong wind gusts around 25-40 mph will develop across portions of Washington County Friday morning to evening, primarily in the Pine Valley Mountains area and favorably oriented canyons such as Black Ridge Canyon.

- A stretch of dry and increasingly mild weather is anticipated over the weekend, with the dry conditions expected to continue for much of the upcoming week.

DISCUSSION, Issued 853 PM MST Thu Nov 5 2026

A weak trough is centered near the Arizona/Nevada/Utah triple point this evening, having split off from a larger storm system over northern Montana. Moisture and instability are limited with this feature, but radar does indicate a few very light showers over eastern Utah that should dissipate over the next couple of hours. Temperatures remain on the cool side today, with maxes running around 5F below seasonal normals.

The trough is expected to continue south, moving into northern Mexico by Saturday, as a broad Pacific ridge builds out eastward over the top of it. This will bring dry conditions Friday through at least the weekend, with temperatures rising to values near or around 5F above seasonal normals through Sunday.

With the presence of the ridge, winds will be generally light and terrain driven. However, the combination of a northerly pressure gradient and weak cold advection will bring some gusty winds to the prone gap areas of Washington county overnight into tomorrow morning. Highest gusts in the area are currently around 25 mph per latest observations, with a decent chance of gusts in excess of 30 mph in isolated spots overnight.

Seeing increasing confidence of the dry conditions continuing through at least much of next week due to the presence of the ridge. There are some indications that a more active pattern may develop for next weekend, but as one would expect, a lot of uncertainty remains in the guidance this far out.

AVIATION

KSLC...No significant weather expected as high pressure builds in. Skies anticipated to remain mostly clear with VFR conditions prevailing. Winds to remain light, generally less than 10 kts, and follow a diurnally typical direction pattern.

REST OF UTAH AND SOUTHWEST WYOMING...High pressure building into the area will limit potential for impactful weather at area terminals. Winds are expected to remain fairly light, following a diurnally typical direction pattern, or at times become variable. Skies will tend to be mostly clear to clear. Some patchy BR/FG potential noted in sheltered valleys (e.g. LGU) overnight through sunrise.
