Temperatures are going to drop in Utah. There could be snow at the highest elevations.

A cold front moves into Utah on Tuesday, turning summer-like weather into autumn. And there is even some snow in the weather forecast.

According to the National Weather Service, high temperatures in the Salt Lake City area will drop from the mid-80s on Monday to the top 60s on Tuesday and the top 50s on Wednesday – temperatures “more typical of late October than late September.”

The cold front will advance through northern Utah in the late morning or early afternoon on Tuesday and continue through the rest of the state on Tuesday evening. From Monday to Wednesday, temperatures drop about 25 degrees in northern Utah and about 10 degrees in southern Utah.

Salt Lake City has a 40% chance of rain on Tuesday afternoon; a 30% chance on Tuesday evening; and a 20% chance Wednesday morning. “By and large, this system will not deliver thirst-quenching rain,” said the weather service. But some “lucky areas” can hold 1 or 2 tenths of an inch of rain.

Snow depth will drop to around 9,000 feet in the Uintas and central mountains, with a “dusting” of a few inches being achieved at the highest elevations.

In Salt Lake City, temperatures will recover somewhat after Wednesday – into the low 60s on Thursday and the high 60s and low 70s Friday-Sunday. The Salt Lake City forecast is not frozen, but overnight lows will be in the top 50s Monday night and 40s Tuesday-Thursday.

Freezing and harsh freezing conditions could occur in normally colder valleys, the National Weather Service warns.

Highs of 90 on Monday and 88 on Tuesday are expected in the St. George area. It will be 81 on Wednesday and gradually warm to almost 90 on Sunday. The probability of rain for Tuesday night and Wednesday is 30%.

The mottled smoke on Monday morning in northern Utah thickens on Monday afternoon and continues on Tuesday morning. In the St. George area, spotty smoke can be expected after midnight on Monday through early Tuesday and Tuesday afternoons.

Salt Lake County’s air quality will be moderate / yellow on Monday and Tuesday and improve to good / green on Wednesday, according to the Utah Department of Air Quality. The same goes for Cache, Carbon, Davis, Duchesne, Tooele, Uintah, Utah, and Weber / Box Elder Counties.

Iron and Washington Counties will be green on Monday, yellow on Tuesday, and green on Wednesday.
