Drastically colder weather and some snow will settle into California and Nevada through Monday night. Gusty winds will spur blowing dust across the southern California deserts, the Las Vegas Valley and Arizona through early Monday night.
The highly traveled Interstate 80 corridor from Reno, Nev., to Sacramento, Calif., can be snow and ice covered in the Sierra at least Tuesday morning. Snow levels will be nearly steady around 6,000 feet through Monday night. Locally dense fog could bring visibility to less than 1/4 of a mile in the Sierra stretch as well.
Farther south, drastically cooler air is on the way for cities like Las Vegas. Monday will have a high in the lower 70s, but temperatures will barely make 60 degrees for Tuesday.
Sugarbowl Ski Resort, situated approximately 1 mile west-southwest of Donner Peak, Calif., reported 15 inches of new snow at the summit and one foot at the base.
Locally strong winds will accompany the cooler weather.
"The deserts of Southern California, the Las Vegas Valley and parts of Arizona will have much cooler temperatures and areas of blowing dust and sand through Monday evening," said AccuWeather.com Expert Meteorologist Ken Clark.
The blowing dust could impact visibility and slow travel in the region, especially for commuters on Interstate 15 between Las Vegas and the L.A. Basin.
There were already strong winds ahead of the storm Sunday night into early Monday morning. Inyo County, Calif., reported a wind gust to 98 mph. Through the day on Monday, winds will be gusting up to 70 mph at the higher elevations of Arizona and Utah as well.
Meanwhile, the Fresno area to just south of Reno could have some rain and thunder on Monday. Fresno reached a high of 80 degrees on Sunday, but a chill will spread into the area on Monday, with highs struggling to reach the lower 60s.
Farther south, some rain will dampen areas from Los Angeles to San Diego.
"Rain will bring slick and wet roads along the Southern California coast on Monday, but it will not be a deluge," said Clark.
By Tuesday, central California will be dry, but some rain and snow showers will linger in Nevada throughout the day. Some rain will linger from Los Angeles to San Diego Tuesday morning as well.
