Bah, humbug! Utah is getting an inversion for Christmas.

There’s no snow in the forecast until Saturday.

Barring some sort of holiday miracle, there won’t be a white Christmas in Utah this year. And, in the weather equivalent of getting coal in your stocking, a building inversion will bring sort of ho-ho-horrible air on Friday.

According to the National Weather Service, the lake-effect showers that left a bit of snow in the Salt Lake Valley late Tuesday and early Wednesday will “diminish quickly,” leaving behind a “clearing and drying trend.”

High pressure aloft will cover areas of northern, central and eastern Utah, with a building inversion that will be moderate on Thursday and strong on Friday. Valley fog is possible throughout the area.

And it’s going to be cold. Salt Lake City will only reach about 30 degrees on Thursday, according to the NWS, with an overnight low of 15. Highs in the mid-30s and lows in the low to mid-20s are expected through the weekend.

There’s snow in the forecast for Saturday — a 60% chance with possible accumulations of less than an inch. That storm is expected to help clear out the inversion.

Down south in St. George, mostly sunny skies are in the offing for Thursday and Friday, with highs in the 50s and lows in the 30s through the weekend. There’s a 20% chance of rain after 11 a.m. on Saturday, but sunny skies will return later in the day and continue on Sunday.
