Salt Lake City, Utah – Rising temperatures will grip northern Utah midweek, with Salt Lake City climbing from 94°F on Wednesday to 101°F on Juneteenth (Thursday) — kicking off the region’s first true heat wave of summer.
According to the National Weather Service in Salt Lake City, a strong ridge of high pressure will build across the Great Basin, pushing daytime highs above 100°F by Thursday afternoon. Salt Lake County residents, especially those traveling along I-15 or working outdoors, should prepare for increased heat strain and dehydration risks.
Wednesday will see calm, sunny conditions with a high near 94°F and light west-northwest winds. But the heat intensifies Thursday, with dry air and full sun driving highs into the triple digits. Friday remains hot, reaching 97°F before a cooler air mass slides in for the weekend.
Health officials advise limiting strenuous activity, especially during peak sun hours from 12 to 5 p.m., and checking on elderly neighbors or pets. Drink water regularly and avoid heat buildup in parked vehicles.
Saturday brings modest relief, with highs dipping to 88°F, followed by a more comfortable 76°F on Sunday. Monday starts the workweek sunny and dry near 84°F.
Stay alert for any upgraded heat advisories or fire danger alerts, particularly as humidity stays low and winds increase into the weekend.
