It’s going to be hot along the Wasatch Front over the next few days, and it’s going to be REALLY hot in southern Utah, according to the National Weather Service (NWS).

An excessive heat warning has been issued for Thursday and Friday in the St. George area, where temperatures are expected to reach 104-107, and around Zion Canyon, with forecast highs of 100-103. The heat will “significantly increase the potential for heat related illnesses,” according to the NWS, “particularly for those working or participating in outdoor activities” and “those without access to air conditioning.”

And residents of those areas will be getting “very little overnight relief” as temperatures will “only briefly bottom out in the low 70s.”

After a high of 101 on Saturday, temperatures will return to the 90s — but just barely. The forecast high for the St. George area is 99 on Sunday.

In the Salt Lake Valley, temperatures are expected to top out in the mid- to upper-90s — as much as 20 degrees above average for this time of year, according to the NWS — and feel “midsummer-like.”

And escaping to higher elevations won’t bring a whole lot of relief. In Park City, it’s expected to hit 80 on Thursday, 87 on Friday, 85 on Saturday and 82 on Sunday.
