“A series of systems will bring much needed rain and snow to the region beginning late tonight and lasting through the weekend. The first system arriving late tonight will bring light showers to the valley and moderate snow accumulations to the mountains. Snow levels will be low with the first system and should bring snow to foothill communities. The second system is much warmer and wetter and will lead to periods of heavy rain and snow this weekend. The valley will see 1 to 3 inches of rain and the mountains above 7000 feet could see up to 3 feet of snow by the end of the weekend.” – NOAA Sacramento, CA
