Snow levels are expected to be in the range of 5,500 to 6,500 feet on Sunday, but then lower to between 5,000 and 6,000 feet on Monday. It’s possible that there could be snow down to the level of the Grapevine, which is at about 4,100 feet, on Monday night, said Curt Kaplan, a meteorologist at the National Weather Service in Oxnard. That cold offshore flow could cause snow levels to dip to the level of the I-5 Freeway through the Tehachapi Mountains. AdvertisementSignificant snow accumulations are likely above 7,000 feet, with lighter accumulations down to 5,000 feet. However, with this second system, snow levels may drop to 4,000 feet on Thursday, which would affect Interstate 5 over the Grapevine.
