341 FXUS65 KSLC 160340 AFDSLC Area Forecast Discussion National Weather Service Salt Lake City UT 940 PM MDT Mon Jun 15 2026 .KEY MESSAGES... - High pressure will bring hot and very dry conditions through the first half of the week, with the hottest temperatures of the season across areas like St. George and Glen Canyon National Recreation area. - Gusty northwest winds combined with a hot and very dry airmass will result in critical fire weather conditions through Wednesday across portions of eastern, central and southern Utah where fuels are critically dry. && .DISCUSSION... Mid level ridging will continue to slowly build inland across the Sierra and western Great Basin region through Wednesday, spreading a hot and very dry airmass across the forecast area. Daytime temperatures will trend a few degrees warmer Tuesday, reaching the low 90s along much of the Wasatch Front, and exceeding 105F across lower Washington County, Zion Canyon, and lower elevations of the Glen Canyon Recreation area. With this ridge remaining centered to the west, a general northwest flow will reside across the area as well allowing for gusty northwest winds, and resulting in critical fire weather conditions where fuels are sufficiently dry. This flow will be enhanced somewhat on Wednesday with a shortwave passing to the north. See the fire weather discussion for more information. This ridge will shift eastward across the forecast area Thursday resulting in lighter winds, but maintaining a very dry airmass. As this ridge continues east, southwesterly flow will spread across the forecast area Friday shifting the fire weather threat to western Utah. An upper trough will translate into the Great Basin Friday through Saturday, resulting in a threat for high based convection mainly across the north. Lingering moisture may keep this convective threat going into Sunday. && .AVIATION...KSLC...VFR conditions will persist at the KSLC terminal beneath clear skies with diurnal wind shifts expected. Gusty winds will develop in the afternoon hours resulting in gusts up to 20kts. REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will persist at all terminals beneath clear skies with diurnal wind shifts expected. Gusty winds are expected to develop across all sites tomorrow afternoon with most seeing gusts up to 20kts, though KEVW may see gusts to 30kts. && .FIRE WEATHER, Issued 225 PM MDT Mon Jun 15 2026... Remnant moisture will bring the threat of isolated high-based thunderstorms and virga to the southern mountains and adjacent valleys this afternoon and evening. Gusty and erratic microburst winds will be the most likely impact. As active weather continues to the north of Utah, an increase in winds will bring critical fire weather conditions to portions of eastern Utah today, spreading to the southern mountains Tuesday. By Wednesday, the stronger winds will shift further south, with critical fire weather conditions expanding to impact the Grand Staircase and Henry Mountains. While winds will decrease Thursday, another disturbance will approach the Great Basin Friday, increasing winds once again, this time across much of central and southern Utah. Wind will remain elevated into Saturday in these same areas. The threat of high- based dry thunderstorms will also increase Friday into Saturday, especially across the northern half of the state. && .SLC WATCHES/WARNINGS/ADVISORIES...
