According to the National Weather Service, it’s going to be hot over Pioneer Day weekend.
After breaking a heat record in Salt Lake City and falling just one degree short of the hottest day on record, more triple-digit temperatures are expected this week.
Sunday marked the hottest day of the year so far, with a high of 106°C. This surpassed the previous record for July 16 (set in 1960, then achieved in 2005 and 2010) by three degrees and was 11 °C above normal for this time of year.
The highest temperature ever recorded in Salt Lake City was 107, set in 1960 and repeated in 2002, 2021 and 2022.
A strong high-pressure system over Utah is keeping the heat up, according to the National Weather Service.
Temperatures are expected to be 5 to 10 degrees above normal across the state on Monday. An extreme heat warning is in effect through 9 p.m. in the Salt Lake, Utah, Tooele and Rush valleys and southwest Utah, including St. George and Zion and Capitol Reef national parks. Heat warnings are in place for the rest of Utah.
A cold front is expected to advance into northern Utah Monday night, but in this case, “cold” is a relative term. Temperatures should drop to mid to high 90°C on Tuesday, Wednesday and Thursday, with a chance of rain and thunderstorms.
However, it is only a temporary relief. Temperatures are expected to climb back into the triple digits on Friday and remain there through Pioneer Day weekend, with the weather forecast calling for scorching highs for Monday’s Days of ’47 parade.
No relief is in sight for southern Utah. High temperatures in St. George will remain at or above 110C through the weekend, according to the Weather Service.
