It’s going to be smoky and hot across much of Utah through Friday. High temperature records could be broken.

The National Weather Service issued an excessive heat warning for the southwestern corner of the state — including St. George and Zion National Park — that ran until Wednesday night, with highs 12-13 degrees above normal for this time of the year. The heat “significantly increase(s) the potential for heat-related illnesses, particularly for those working or participating in outdoor activities.”

In Salt Lake City, the forecast high is 97 on Thursday, before dropping back to 90 on Friday.

And the air quality isn’t going to be good. Smoke from West Coast wildfires will continue to drift over the state.

There’s a chance of showers Friday night and Saturday in northern Utah, when temperatures are expected to be in the 80s.

There will be a little bit of a cool-down in southern Utah, but only a little bit. It’ll be 107 on Thursday and 103 on Friday, according to the National Weather Service, and in the low triple digits through Monday.

There is no precipitation in the forecast for southern Utah.
