Al Hartmann | The Salt Lake Tribune Aspen trees are reaching their peak colors in Big Cottonwood Canyon Wednesday September 25. Fall is in its full glory but a winter storm will paint the high country with the first dusting of snow.

Time to dig those jackets out of the cedar chest, Utah: A cold front has moved into the region and plans to stay for a while.

Temperatures along the Wasatch Front plunged Wednesday, making summer a memory.

By Wednesday evening, area ski resorts — including Alta, Snowbird, Snowbasin and Powder Mountain — had a dusting of snow.

There were also snow flurries near the summit of Parleys Canyon during the afternoon.

The daytime highs for Thursday were forecast to retreat into the mid-50s, down about 5 degrees from already chilly temperatures forecast on Wednesday.

And then there’s the wind. Gusty weather was expected throughout the state through late Wednesday night, though it was much of the southern third of Utah that was under a Wind Advisory from noon to 10 p.m. on Wednesday.

Add to the mix isolated rain showers throughout northern Utah, with some snowfall predicted in the mountains above 5,000 feet elevation.

The National Weather Service predicted winds of 25-35 mph with gusts topping 50 mph during the advisory period.

Along with the wind, southern Utahns looked for highs in the low- to mid-80s Wednesday to give way to daytime temperatures in the 70s on Thursday.

All that atmospheric mixing meant “Green,” or healthy air quality for the state from north to south. The Utah Division of Air Quality predicted those conditions will remain into the weekend.

The Intermountain Allergy & Asthma website had good news for allergy sufferers in general, though sagebrush pollen was the exception, coming in “very high.” Ragweed was at “moderate” levels.

Salt Lake City’s high temperature Thursday was pegged at 53, down sharply from the 65 degrees predicted Wednesday; Ogden looked for 52 and 60 degrees, respectively; Provo 59 and 69; Logan 50 and 57; Wendover 54 and 61; Duchesne 61 and 69; Cedar City 62 and 73; St. George 75 and 86; and Moab 79 and 82 degrees.
