KEY MESSAGES, Issued 113 PM MDT Wed Jul 1 2026

- Locally or marginally critical fire weather conditions will continue through the week for areas of central, eastern, and southern Utah.

- Temperatures will continue to warm through next week, peaking early next week ~5 degrees above normal, with warm overnight lows as well.

- High-based convection across northern Utah/SW Wyoming will remain possible (~25% chance) through Friday with gusty winds the primary concern.

- Moisture increases early next week as a ridge sets up over the 4 corners region which could lead to diurnal convection across the area.

DISCUSSION, Issued 113 PM MDT Wed Jul 1 2026

A shortwave embedded in the southern periphery of a mean longwave trough across the PNW is moving through the region today. This, paired with weak instability and modest DCAPE values, will result in some isolated convection this afternoon across northern Utah and SW Wyoming. Moisture is lacking in the lower levels with inverted V profiles noted in model soundings will make for a conducive environment for gusty winds. SPC has issued a marginal risk across far northwestern Utah associated with this convection for the threat for gusty winds.

With midlevel moisture remaining in place across the north through Friday and more shortwaves passing through the area, isolated diurnal convection will remain possible (~25% chance) across the area. With limited moisture at the surface gusty winds and little in the way of appreciable rainfall will be the most likely scenario.

With these shortwaves over the next couple of days southwesterly flow will produce some gusty winds that will lead to some marginal critical fire weather conditions. The trend with these winds has been a little downward over the last several model runs, so the probability of needing fire weather products continues to trend down, but this will be monitored to see if things change.

Much drier air filters into the area this weekend as a ridge starts to build across the 4 corners. This will keep the area dry with lighter winds. Temperatures will start to climb above normal by Sunday. By early next week moisture starts to get advected into the area with average PWATs in the 0.5-0.7" range across the area. Diurnal convection will result with terrain being the favored areas of development.

AVIATION, Issued 113 PM MDT Wed Jul 1 2026

KSLC...VFR conditions are expected to persist through the TAF period. A few gusty high-based thunderstorms are possible near the terminal over the next 6-8hrs, though confidence regarding location remains too low at this time to include in the TAF.

REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions are expected to persist through the TAF period. High-based gusty thunderstorms are possible across KLGU and KEVW over the next 6-8hrs, though confidence remains too low at this time to include in the TAF and may be amended.

FIRE WEATHER

Locally critical fire weather conditions exist across the southern and eastern parts of the area as relative humidity in the upper single digits to low teens persists with wind gusts in the teens to low 20s. Overnight recoveries will also remain poor. This pattern will continue through Friday as similar disturbances move through. Winds will likely remain just below fire weather product criteria as model trends have been for slightly weaker winds. This will be monitored though for any updates on future shifts. Additionally, isolated diurnal high- based convection across northern Utah will remain through Friday with the primary threat being strong gusty outflow winds.

High pressure starts to build into the area this weekend that will suppress diurnal convection and increase temperatures. More mid- level moisture advects into the area early next week with diurnal terrain based convection chances increasing.
