SALT LAKE CITY — More snow is expected to begin Wednesday across the Wasatch Front as Utah prepares for treacherous Thanksgiving travel conditions.
The snow will move into Utah Wednesday and is expected to stall over the state from Brigham City to Cedar City on Wednesday night, according to the National Weather Service. Heavier snow will be present on the Wasatch Front Thursday, the weather service said.
On Friday, the snow, again, will continue at various times throughout the day. Precipitation will gradually diminish Saturday, according to the weather service.
By the weekend, the valleys of northern Utah will see between 5 and 10 inches of snow, according to KSL Meteorologist Grant Weyman. Benches could see up to 18 inches, and some areas of the mountains could see 3 feet of snow.
"We’re basically looking at waves of snow at times today, at times tomorrow, at times Friday," Weyman said. "So by the time we get to the weekend, a lot of us could have between 5 and 10 inches of snow on the ground, the mountains 1-3 feet of snow. But again that’s not all going to happen today, that’s going to be at times through the end of the week."
Downtown Salt Lake City will see most of the winter activity Thursday, Weyman said. Another part of the storm will be moving into the area and winds will shift on Thanksgiving day, allowing for more winter weather to start in Salt Lake City, he said.
Higher elevation areas, such as Park City and Sardine Canyon, will be more heavily impacted Wednesday, Weyman added.
Wind gusts are affecting northern Utah today, with gusts of 30-45 miles per hour present in some areas, Weyman said.
Wednesday is the heaviest travel day of Thanksgiving week, according to the Utah Department of Public Safety.
Holiday traffic on I-15 in Utah is expected to be at its heaviest between 2 and 7 p.m. Wednesday, the agency said. Travelers are advised to leave earlier in the day or late in the evening to avoid delays.
After Thanksgiving, travel activity will be highest from 3-7 p.m. on Sunday, the Department of Public Safety said.
The winter weather will impact roads throughout the state for the rest of the week, according to the Utah Department of Transportation. All mountain routes, as well as most valley roads, will be affected.
As of 8 a.m. Wednesday, tire chains or four-wheel drive is required in Big Cottonwood and Little Cottonwood canyons, according to UDOT.
In southern Utah, state Route 143 is closed from Brian Head to Mammoth Springs due to weather conditions. In Wyoming, U.S. Highway 191 is closed in both directions from I-80 to the Utah-Wyoming state line due to weather conditions.
