KEY MESSAGES, Issued 113 PM MDT Tue Sep 8 2026

- Dry conditions are expected to persist with gradually warming temperatures pushing back 5-10 degrees above normal by Thursday.

- Winds increase this weekend ahead of a cold front that could bring more precipitation back to portions of the CWA.

DISCUSSION, Issued 113 PM MDT Tue Sep 8 2026

Westerly zonal flow will persist through the end of the week as we remain sandwiched between the active northerly stream across the northern Intermountain West and a ridge across the southwest. This will keep dry air in place over the next few days along with light and diurnally driven winds in addition to temperatures warming back above average by the end of the week. It will return to hot conditions across lower Washington county Wednesday-Friday with highs in the low 100s.

A trough will likely (90% chance) swing through the northern Intermountain West this weekend that will bring a cold front through Utah/SW Wyoming late Saturday through early Sunday. Southwesterly winds will increase ahead of this frontal passage with ~35% chance of seeing winds 45+ mph across the western half of Utah. Additionally, moisture starts to creep back into the eastern half of the state on Friday and Saturday. Guidance continues to trend towards moisture remaining across eastern Utah.

The airmass behind this cold front will be very similar to this prior cold front that pushed through over the weekend. The pattern of warm days and cool nights is upon us and will continue through the foreseeable future.

AVIATION

KSLC...VFR conditions will persist throughout the entire forecast period. Northwesterly winds will prevail until 4Z before shifting to light southeasterly winds. Occasional northwesterly wind shifts can't be ruled out, especially between 10-14z.

REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions are forecast to prevail across all regional terminals through the TAF period. Diurnal winds are expected across all TAF sites, with the potential of KPVU seeing wind gusts around 22 knots starting 20z this afternoon and subsiting around 4Z this evening.

FIRE WEATHER, Issued 113 PM MDT Tue Sep 8 2026

Dry and warm conditions will persist throughout the week due to westerly winds aloft. This will keep minimum relative humidity in the teens and upper single digits for much of the area through much of the week. RH will improve overnight into the 30s and 40s given the cooler temperatures. Moisture starts to slowly creep back into the area by this weekend ahead of an approaching cold front. This cold front will increase southwesterly winds on Saturday with gusts 30-45 mph expected, particularly across western portions of Utah. This will result in locally critical fire weather conditions as min RH will remain in the teens across locations near the Nevada border. This cold front will move through late Saturday/early Sunday with winds weakening behind the front. Moisture associated with this front remains a bit more uncertain with a low chance of precipitation most likely across eastern Utah Friday/Saturday.
