After a warm start to the week, here’s how much rain and snow Salt Lake will get

Rain and snow will fall, and so will the temperatures.

(Francisco Kjolseth | The Salt Lake Tribune) Commuters make the drive on slick roads along Foothill Drive in Salt Lake City Friday, Dec. 10, 2021.

It’ll be considerably warmer than usual across much of northern Utah on Tuesday, but that’s only the warm before the storm that the National Weather System is forecasting for Tuesday night.

Highs in the Salt Lake City area will be about 50 on Tuesday. That’s 18 degrees above the normal high for the date — 32 degrees.

The record high for the date was set in 1929 at 64 degrees; the record low was 15 degrees in 1932.

Tuesday evening storm

On Tuesday, there’s a slight chance of rain and snow before 11 a.m., then a 50% chance of precipitation, with little or no snow accumulation expected. Winds will be 18-26 mph, with gusts as high as 44 mph.

On Tuesday evening though, the probability of precipitation rises to 90%. Rain and snow are expected between 11 p.m and 2 a.m. Wednesday, then snow after 2 a.m. Up to 2 inches of accumulation is possible in the valleys; 2-5 inches on the benches; and 1-2 feet in the mountains.

The storm will continue into Wednesday morning, brining a 40% chance of more snow and accumulations of less than half an inch in the valleys before 11 a.m. And temperatures will drop to normal — about 31 degrees.

Looking ahead, there’s a slight chance of more snow Wednesday night, and a 70% chance of snow on Thursday. Temperatures will be in the low to mid-30s through the weekend.

Southern Utah weather

In southern Utah, temperatures in the mid-50s are expected Tuesday, which are normal for this time of year, according to the National Weather Service.

There’s an 80% chance of rain in the St. George area after 11 a.m. That rises to a 100% chance of precipitation on Tuesday night into early Wednesday, when a mix of rain and snow is possible as temperatures fall to about 32 degrees. Little or no snow accumulation is expected in the valleys, but about 2 feet is possible in the mountains.

Expect a mix of sun and clouds in southern Utah through Sunday, with high temperatures in the low to mid-40s.
