Another cold low-pressure system off the California coast will dig south overnight with snow showers increasing in coverage and intensity. Snowfall could become locally heavy through Wednesday morning as lows drop into the teens and lower 20s, with highs only in the 20s. The snow level should drop as low as 3,000 feet, possibly lower, with additional accumulations of 1-2 feet likely. This is a very cold, arctic airmass, resulting in a higher snow-water ratio, which should allow the snow to pile up with snowfall rates approaching 2-3 inches per hour overnight. Strong westerly winds will also accompany this storm, with gusts near 50 mph possible, making for extremely treacherous travel in blizzard-like conditions and below-zero wind chills, travel is not recommended! The heavier snowfall will become more showery by afternoon but continue at times into Thursday as one last disturbance moves through the area. Our broad troughing along the West Coast will slide east on Friday, allowing some weak ridging over the weekend. Expect fair and warmer weather on Saturday and Sunday as highs make it back into the 40s, a nice opportunity to dig out. Additional storms are possible next week, but the details are unknown at this time. A quick check shows potentially higher snow levels with the storm on Monday as we tap into another atmospheric river. If you have travel plans this week in the mountains, be prepared for dangerous driving conditions in near white-out and blizzard-like conditions, and always carry tire chains! R2 restrictions remain in effect on all mountain roads at this time. For the most up-to-date chain restriction information, check socalmountains.com (click here)
