Storms continue to form in this area and then move along the jetstream and into California. A few days ago it was thought that these storms would be hitting northern California and we would be bouncing between the warm side and the cold side of the jetstream and would be receiving heavy precipitation with higher snow levels. Well, as you can see on the picture, the main impact area of the storms is to the south of us. We are on the cooler side of the jetstream and will actually have colder air move into our area tonight and Monday.
While we will have wet weather off and on for the next week, it now looks like the central and southern sections of the state will get the heavier precipitation. The snow level in the north end of the state is currently around 4,000 feet, while Blue Canyon at the 5,200-foot elevation in the Tahoe area is in the mid- to upper-30s and has received over 3 inches of rain in the last 24 hours.
Today and most of Monday we will have periods of rain or showers, with the snow level dropping this evening to 3,000 to 3,500 feet north and 4,500 to 5,000 feet south (Plumas County). We will have somewhat of break Monday evening through Tuesday. During these periods, we will have partly cloudy to cloudy skies with scattered showers in the mountains and just isolated activity in the valley. Another storm system will move into northern California Tuesday night and Wednesday with more wind and precipitation. Snow levels will be 3,000 to 4,000 feet north and 4,500 to 5,500 feet south (Plumas County). We will have another sort of break between systems Thursday and Friday, with partly cloudy to cloudy skies but continued scattered showers in the mountains. The map below for Christmas Day shows the Gulf of Alaska low pressure area once again extending toward the west coast and this should bring another storm into the north state on Christmas Day.
