A Pacific storm is now moving into northern California. The clouds have arrived, the wind is getting stronger, and we can expect areas of rain and snow tonight, and it will be heavy at times. Snow will fall down to the valley floor through Wednesday morning. A cold front is pushing toward the California coast this evening and will move over northern California through the night and morning. A High Wind Warning and Winter Storm Warning are in effect. Overnight lows will range from the 20s in the mountains to the 30s in the valley and foothills. The mountains will get more snow while the valley will have snow warming to rain late tomorrow morning. The strong wind will continue. Highs will range from the 30s to the 40s for all areas.
More heavy rain and snow will fall late Wednesday and Thursday. Both are still possible Friday, but it won't be as heavy, and more rain and snow will fall this weekend through the first couple days of next week. Blizzard Warnings are in effect for the Sierra through Friday morning, and mountain road travel is discouraged and may not be possible by late this week. Valley areas can expect several inches of rain, while our highest mountains may receive over 6 feet of snow. We may have an end to the widespread rain and snow by the middle to latter part of next week, as a ridge of high pressure begins to build over the West Coast. Highs will gradually warm from the 30s and 40s to the 40s and 50s for the mountains and valley.
