KEY MESSAGES

- High pressure will keep conditions dry and mild over Utah and southwest Wyoming through the weekend.

- A weak storm system will move through the area Monday night into Tuesday, curbing the warming trend and bringing a very low chance of showers.

- A more active pattern may develop next weekend.

DISCUSSION

High pressure remains in place over Utah this evening, though slightly flattened due to a trough crossing the Idaho Panhandle and heading into Montana. The high pressure will rebound over Utah over the weekend, with greatest heights on Sunday. Patchy high clouds will continue crossing the region through Saturday, otherwise dry and stable conditions can be expected under this pattern. Temperatures will very gradually trend warmer through Sunday.

On Monday, the ridge axis will shift east as a weakening trough moves into the Great Basin. This trough is expected to cross Utah Monday night into Tuesday. Expect generally little impact from this trough. Latest models continue to trend lower on QPF. The NBM 75th percentile has mostly 0 QPF across Utah with this trough, with less than 0.05 inches over the Uintas. Temperatures should drop slightly by Tuesday. High pressure is then progged to build back into the area for the second half of next week.

Southwest flow may increase next weekend ahead of a potentially deepening trough. However, while the majority of global ensembles depict some sort of trough moving into Utah late next weekend or early next week, cluster analysis of global ensembles currently show appreciable model spread in terms of the strength and timing of any such trough.

AVIATION

KSLC...VFR conditions will persist for the KSLC terminal through the period. Dry and stable conditions along with a few high clouds will continue with light and diurnally driven winds.

REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will persist for the entire airspace through the period. Dry and stable conditions along with a few high clouds will continue with light and diurnally driven winds.

FIRE WEATHER, Issued 235 PM MDT Fri Oct 2 2026

High pressure will keep conditions dry, mild, and stable through the weekend with winds staying light. A weak storm system will curb the warming trend as it passes through late Monday into Tuesday, and will likely bring a very slight increase in relative humidity. High pressure will build again beginning midweek, with at least some potential for a more active pattern to develop by the beginning of next week.
