According to the National Weather Service, snow levels could fall to as low as 1,000 feet Friday evening, before turning to showers on Saturday.

Heavy snow and gusty winds could cause whiteout conditions with visibility near zero, especially above 5,000 feet. Accumulating snow is expected over the Golden State (5) Freeway and Antelope Valley (14) Freeway late Friday tonight and Saturday.

Visibility could be "near zero" at times along the Grapevine, with winds of 20-30 mph, gusting to 50 mph, the Weather Service reported.

A winter storm warning means significant amounts of snow are expected. Travel through the mountains is "highly discouraged," according to the Weather Service.

The rain will get heavy at times ... (and) once the front comes in we will get cold air and rain, which means thunderstorms."
