A cold front moving into northern Utah from Idaho could dump up to three inches of snow in valley locations Monday night, said Bill Alder, meteorologist in charge of the U.S. Weather Bureau's Salt Lake office.
Alder said the Cache Valley area would likely get the most snow with areas as far south as Nephi along the Wasatch Front getting lesser amounts.Mountain areas will likely get between eight and 12 inches of new snow from the system. However, ski resorts in Big and Little Cottonwood canyons could get as much as 18 inches of new snow.
"Little Cottonwood Canyon is configured in such a way that a northwest flow is beautiful as it comes in and lifts all the way up to the Snowbird and Alta areas and pulls everything out of the storm," Alder said.
A heavy snowfall Monday could mean a record November for Alta where 50 inches fell during the weekend. By Sunday, the resort had accumulated 123 inches, short of the record 143.5 inches. Earlier forecasts did not give Monday's predicted storm enough punch to challenge for the record, but the updated forecast could change that.
Alder said conditions in advance of the storm will be windy and there could be some drifting near the point of the mountain and in the west part of the valley.
Tuesday will see partly cloudy conditions and colder temperatures. Monday's high is expected to be near 45 with the high dropping to about 38 on Tuesday. A high pressure system is expected to move into the area beginning Tuesday, creating stagnant conditions that will allow haze and smoke to settle into the valley along with patchy fog beginning Wednesday, Alder said.
