The National Weather Service in Sacramento is warning residents of an active weather pattern extending into early next week, with rounds of mountain snow, rain, and gusty winds potentially affecting travel across the region. Winter Storm Warnings are in effect until 10 PM Saturday for elevations above 3,500 feet in the Shasta County mountains and above 5,000 feet for the Southern Cascades and Sierra. A Wind Advisory is also in effect from 10 PM Friday to noon Saturday for parts of the Sacramento Valley and Delta, with gusts reaching up to 45 MPH.
According to the National Weather Service, the recent rain in the valley has subsided, leaving snow showers over the Sierra. Snow rates have decreased, but travelers are urged to remain cautious as chain controls remain in place. Over the past 24 hours, valley locations received between half an inch and an inch and a half of rain, while mountain areas saw up to an inch of snow. Another wave of precipitation is expected to begin early Friday morning, intensifying through Saturday afternoon, with the potential for heavy snowfall and significant accumulation at higher elevations. The National Weather Service warns that these conditions may lead to difficult travel due to snow-covered and slippery roads and advises checking road conditions with CalTrans or by dialing 511.
The National Weather Service forecast predicts 8 to 24 inches of snow above 3,500 feet in Shasta County, with even higher amounts along the peaks, accompanied by wind gusts up to 45 MPH, creating hazardous travel conditions. The Sierra and Southern Cascades could receive 1 to 3 feet of snow above 5,000 feet, with potential accumulations greater than 2 feet, especially north of I-80. In addition to the snow, strong winds are expected across the region, with the northeastern foothills and Delta facing gusts stronger than 40 MPH, with a 60-95% probability.
Stormy conditions are expected to ease by Sunday morning, leading to a brief period of mostly sunny skies and lighter winds. However, another system is forecast for Monday, though it appears less intense. Current projections suggest snow accumulations of 4 to 10 inches above 6,000 feet, with lighter rainfall in the valley. Looking ahead, another fast-moving system is expected Monday, bringing additional precipitation and mountain snowfall. Snow levels will start at 3,500 to 5,000 feet on Monday, rising to 4,500 to 5,500 feet by Tuesday morning. Improving conditions are expected after the system passes, with a 30 to 60% chance of receiving half an inch or more of rain north of I-80. Despite the forecasted intensity, Monday's impact is expected to be less severe than the stormy conditions over the weekend.
