Bundle up, and keep your umbrella handy early today. We've been tracking showers sagging South of the Oregon border this morning. Scattered showers have spread across the Northern Mountains, and portions of the Sierra. Snow will bring travel impacts to Northern zones of the state today. High pressure should push most of that moisture back into Oregon around noon. Temperatures have dipped into the low 30's to low 40's in the valley this morning, and into the teens to around 30 degrees in the mountains. High temperatures are expected to end up in the low to mid 50's in the valley, and mountain areas will end up in the low 40's to low 50's this afternoon. Winds will be light today. Mostly areas will just be dry and cloudy for your afternoon.
Saturday will be cloudy, dry, and have the same range of temperatures as today. Showers will return to the Northwest corner of the state early in the day on Christmas Eve, and will then spread into most areas of Northern California by the evening. The majority of the showers are expected in the mountains, and current projections put snow levels at around 5000 feet. Winds are not expected to be a big issue with that system. Showers will then taper off late Christmas Eve night into early Christmas Day. Some sunshine, dry conditions and warmer temperatures are ahead for Christmas day.
Showers will likely return to the mountains on Tuesday and Wednesday, while valley areas stay dry.
