The hot summer is set to kick it up a notch as most of Utah will be stuck on high heat Thursday through Monday.

The state will see the worst of it through Saturday, particularly in southern Utah — there’s an excessive heart warning in Washington County. Near record highs are anticipated through the first half of the weekend.

The forecast highs for St. George are 109 degrees on Thursday, 110 on Friday and 111 on Saturday. The records in place for those days are 113 (1995), 110 (1996) and 112 (1995), respectively.

The Lake Powell and Glen Canyon recreational area and Grand Staircase monument are also under excessive heat watch Friday and Saturday.

The heat won’t stay concentrated in southern Utah as Salt Lake City is expected to hit triple-digit highs Friday through Monday. Areas that don’t experience temperatures over 100 degrees will still see highs above normal for late July and early August.

Salt Lake County will offer two cooling centers for residents who don’t have air conditioning — at the Salt Palace Convention Center (100 S. West Temple, Salt Lake City) and the Mountain America Expo Center, (9575 S. State Street, Sandy). Open July 30-Aug. 7 from noon to 7 p.m., the facilities will enforce social distancing protocols and require visitors to wear a face covering. People with any COVID-19 symptoms are asked to stay away.
