Heavily traveled mountain passes in Kern County such as Tejon Pass over the Grapevine and Tehachapi Pass will be affected by snow late Sunday night and into Monday.
Snow will continue, heavy at times, through Sunday evening. Additional snow accumulations of up to 1 foot with total snow accumulations of 2 to 4 feet are possible above 7000 feet through Sunday evening.
In addition to the snow, strong southwest winds will affect the higher elevations until midday Sunday and create considerable blowing and drifting snow with local whiteout conditions. Local wind gusts of 80 mph or higher will occur along the Sierra Crest.
A winter storm warning means significant amounts of snow are expected or occurring. Strong winds are also possible.
Very cold air has moved into the region as snow levels lowered this morning to around 4000 feet and may continue to drop to around 3500 feet by Sunday night. A low pressure system will pass to the south of Kern County and will provide plenty of moisture for snow across the region.
A few snow showers will occur Sunday as the cold air settles in. Then by tonight as the storm makes its way into the area snow will begin to pick up and become very heavy at times.
The forecast amounts above 5000 feet will be from 6 to 11 inches with locally heavier amounts at Frazier Park and Cuddy Valley where snowfall amounts could be over a foot.
A snow and blowing snow advisory means that visibilities will be limited due to a combination of falling and blowing snow.
Persons should curtail their travel plans if their destination includes the mountains and national parks. Many roads leading into the higher elevations will either be closed or require chains during this time.
