Chances are, you don't need us to tell you that it's hot outside. If you do: It's hot outside.

After hitting 100 degrees for the first time this year on Saturday, Salt Lake City can expect highs of 104 on Sunday and Monday. Temperatures in St. George are expected to reach 108 on Sunday, followed by 107 on Monday, according to the National Weather Service.

Meteorologists expect the extended heat wave to continue through the week for most of the state, with highs each day averaging 10 to 15 degrees above normal, according to the weather service.

"With very hot temperatures, heat safety precautions need to be taken," the weather service urged in a statement. "Learn the symptoms of heat stroke and heat exhaustion. If you notice these symptoms in yourself or anyone around you, seek immediate medical attention if necessary."

The air isn't just hot — it's not that clean, either, according to the Utah Division of Air Quality. Salt Lake, Davis, Weber, Utah and Tooele counties' air quality is coded "orange" unhealthy for sensitive groups, on Sunday and Monday. Box Elder, Carbon, Duchesne, Uintah and Washington counties have moderate air quality both days.
