KEY TAKEAWAYS
  • Winter weather advisories issued for Wasatch Mountains as new storm approaches Utah.
  • Forecasters predict rain in valleys and snow in higher elevations across Utah's northern half between Tuesday and Wednesday.
  • Warmer, drier conditions expected by week's end.

SALT LAKE CITY — More snow is headed Utah's way this week, but forecasters don't expect the latest storm to produce quite as much as last week's beneficial pattern.

The National Weather Service issued winter weather advisories for the Wasatch Mountains, where some higher-elevation areas could receive another foot of snow between Tuesday morning and Wednesday afternoon.

Valley communities are much more likely to receive rain this time around because of the warmer nature of the decaying atmospheric river making its way into the state from the Pacific Northwest, said KSL meteorologist Devan Masciulli.

"This storm that we're tracking is mostly going to impact north and parts of central Utah," she said.

Valley rain and high-elevation mountain snow are possible across northern Utah on Tuesday morning, but more widespread showers are forecast across the Wasatch Front and northern Utah in the afternoon.

Showers are expected to impact the region in the evening and most of Wednesday, before finally clearing out by the end of the day.

Storm accumulations

The incoming system is similar to many of the storms before last week, with a much higher snow line. Snow levels might start as low as 6,500 feet elevation, but they are expected to rise to 8,000 feet by Tuesday afternoon and possibly as high as 10,000 feet elevation heading into Wednesday, according to the advisories.

Federal forecasters say the storm could produce 2 to 8 inches of snow in parts of the Wasatch Mountains above 8,000 feet, and 6 to 16 inches of snow in areas above 9,000 feet. Slightly higher amounts are possible in the Bear River Range and upper Cottonwood Canyons.

Parts of the Uinta Mountains could receive 5 to 10 inches, Masciulli adds. Higher-elevation communities like Park City could receive a little bit of snow, but rain is more likely as the snow line changes.

Communities across the Wasatch Front and northern Utah could also receive 0.25 to 0.75 inches or more of rain by the end of Wednesday.

Areas south of central Utah are likely to be skipped entirely.

Warm end to workweek

The incoming storm is expected to boost Utah's important statewide snowpack, which is currently 64% of normal to start this week. However, warmer and drier conditions are expected by the end of the workweek.

"We'll have a quiet end to the workweek," Masciulli said. "It's going to feel really pleasant, but not ideal for this time of the year."

High temperatures in the Wasatch Front and northern Utah are forecast to return to the upper 50s and low 60s by Friday and Saturday, while high temperatures are expected to reach the mid-70s in and around St. George. Those are approximately 10 degrees above the normal for late February.

Another storm system could impact Utah's northern half toward the end of the weekend. Full seven-day forecasts for areas across Utah can be found online at the KSL Weather Center.
