Salt Lake City, Utah — An unseasonable surge of early-season heat will build across Utah starting Friday, May 8, pushing temperatures well above normal and increasing risks for travel and outdoor exposure across Salt Lake City, St. George, Provo, Ogden, and Logan.
According to NOAA’s Climate Prediction Center, temperatures will trend 70–80% above normal through May 14, with the most intense heat arriving Friday afternoon. The peak window runs from 2 p.m. to 7 p.m. Friday and Saturday, when valleys and desert مناطق will heat rapidly under strong high pressure.
That heat will translate into immediate impacts. Road surfaces along I-15 and I-80 may become extremely hot during peak afternoon hours, increasing the risk of tire blowouts and vehicle overheating, especially across long stretches between Salt Lake City and southern Utah. In urban corridors like Salt Lake City and Provo, heat will build quickly on pavement and concrete, raising surface temperatures well above the air temperature.
Limited overnight cooling will add to the strain. Temperatures will remain elevated after sunset, particularly along the Wasatch Front, reducing relief and increasing exposure risks for outdoor workers and those without reliable cooling.
Dry conditions combined with heat may also elevate fire risk across southern Utah, especially near St. George and brush-heavy terrain where vegetation can dry rapidly.
This is part of a broader expansion of high pressure pushing heat across much of the western United States during this period.
Residents should limit outdoor activity during peak afternoon hours, stay hydrated, and avoid prolonged sun exposure. Drivers should check vehicles before travel and remain alert for heat-related issues on highways.
The highest risk for heat-related impacts will occur each afternoon between 2 p.m. and 7 p.m. Friday through Sunday.
