Salt Lake City is starting Sunday, August 16, under mostly clear skies and around 70 degrees, but the calm morning will give way to a week of increasingly stubborn heat. An airport observation shortly before dawn recorded southeast winds near 33 mph, while the forecast calls for those winds to ease to about 5 mph later Sunday.

Sunday Starts Mild, Then Turns Hot

Temperatures should climb quickly through the morning, reaching the low 80s by late morning and a high near 90 Sunday afternoon. Skies stay sunny with just a 4% chance of rain, making for a dry day across Salt Lake City.

The pattern keeps warming Monday through Friday, with highs near 92 Monday, 93 Tuesday, 94 Wednesday and 96 Thursday and Friday. Overnight lows remain mostly between 66 and 71 degrees, leaving limited relief after sunset.

Storm Chances Return Late In The Week

The National Weather Service says the next monsoon surge is becoming more likely Friday, when measurable rain becomes a better possibility for much of the region. In Salt Lake City, rain chances remain modest at 15% Friday, 25% Friday night and 28% Saturday, so the late-week shift looks more like an interruption than a washout.

Fire Weather Concerns Increase Elsewhere In Utah

The forecast discussion flags elevated to locally critical fire weather conditions Tuesday into Wednesday across central and southern Utah, where dry air and low humidity could make fires spread more easily. No watches or warnings are posted for Utah in the current report, but the combination of heat, dry air, and open flames still calls for caution during outdoor recreation and burning activities.
