Temperatures along the Wasatch Front are forecast to spike into the triple digits Thursday through Thursday, Aug. 6–8, bringing potentially record-breaking heat to Bountiful and South Davis County just as wildfire smoke continues to foul the air.
"Hot temperatures and likely record-breaking temperatures will return for many with Salt Lake seeing forecasted highs of 104° both Friday and Saturday," ABC4 forecaster Cedric Haynes wrote Wednesday. His 4Warn Weather team said heat alerts will "most likely" be issued for the Wasatch Front as a strengthening high-pressure ridge pushes temperatures sharply higher beginning Thursday.
The heat follows a week of degraded air quality across Davis County. As we reported Monday, wildfire smoke pushed conditions into the unhealthy range through Wednesday. That advisory has expired. But smoke from the Widemouth Fire in central Utah and blazes in Nevada and the Pacific Northwest continues to drift over the Wasatch Front, keeping air quality in the "Unhealthy for Sensitive Groups" category.
Why overnight matters
Overnight lows are forecast to drop only into the 70s and 80s, offering little relief. That lack of nighttime cooling raises the risk of heat-related illness, particularly for older adults, young children, people with lung conditions and outdoor workers. The NWS heat risk is expected to reach the "major" and "extreme" categories for most valley areas.
In guidance issued ahead of a similar heat event on July 30, the National Weather Service urged residents to drink plenty of fluids, stay in air-conditioned spaces, avoid direct sun and check on relatives and neighbors. The agency warned that vehicle interiors can reach lethal temperatures within minutes and that young children and pets should never be left unattended in cars.
Staying cool locally
The South Davis Recreation Center, 550 N 200 W in Bountiful, offers air-conditioned space and pool access through the heat wave. Summer hours run Monday through Friday, 5 a.m. to 9 p.m., and Saturday, 6 a.m. to 9 p.m. Indoor pools open at 12:30 p.m. weekdays and 12:30 p.m. Saturdays.
No Davis County cooling center list has been published for this event. Salt Lake County opened more than 60 cool zones ahead of the late-July heat wave, according to KSL, but a parallel Davis County program has not been confirmed.
Summerfest lands on the hottest days
The Bountiful Davis Art Center's Summerfest Folk & Heritage Arts festival is scheduled for Friday and Friday, Aug. 7–8, noon to 8 p.m. at Bountiful City Park, 400 N 200 W. The free outdoor event features live performances, food trucks and artist vendors. No statement from organizers about heat-related modifications has been released.
Attendees planning to spend hours outdoors at Summerfest or other weekend activities should bring water, seek shade and watch for signs of heat exhaustion: heavy sweating, weakness, nausea and dizziness.
Relief in sight
Forecasters expect some cooling by Sunday, Aug. 9, as monsoonal moisture returns. Northern Utah's best chances for rain showers arrive by Monday, Aug. 10.
Residents can monitor real-time air quality through the Utah Division of Air Quality and check heat alerts through the National Weather Service's Salt Lake City office.
