The strongest storms of the season arrived this week bringing snow and precipitation to NorCal. Heavy Valley rain and multiple feet of snow are forecast for the mountains and foothills continuing Tuesday- Friday. Mountain travel is highly discouraged as snow will create treacherous driving conditions. If you must travel, carry chains, have an emergency kit and check road conditions before you go at quickmap.dot.ca.gov.
A Hard Freeze Watch is in effect for elevations below 2000 feet late Monday night into Tuesday morning. Overnight lows as low as 25 degrees are possible. Protect pipes, plants, people and pets.
Snow over the Sierra Nevada has tapered off this morning, so the Winter Weather Advisory will be allowed to expire. Travel impacts still remain from snow covered roads, so be sure to check road conditions before traveling today. Snow may linger into the evening hours in the Central Sierra but any additional amounts will be light.
A significantly stronger, wetter storm will move into the region late Tuesday and persist into Friday. Very low snow levels to start with strong winds are expected. Total snow accumulations of 5 to 10 inches, with localized amounts up to 2 feet, are possible. Snowfall will be possible down into the far northern Sacramento Valley late Tuesday into Wednesday morning. Snow levels will generally rise to 3000 ft or above during the day on Wednesday. An abundance of snow will be possible in the Sierra and southern Cascades with this storm that will make travel very difficult to impossible for the week.
Strong southerly winds are possible Tuesday night and Wednesday. Wind gusts up to 35-50 mph are possible in the Valley, 40-50 mph in the foothills and mountains, and up to 60+ mph along the Sierra crest. Wind this strong could cause downed trees and power lines.
