Medford, OR – Travel conditions are expected to deteriorate across higher-elevation highways in northern California and southern Oregon beginning Saturday night, as a new round of snow moves into the region, according to the National Weather Service in Medford.
The National Weather Service reports that the heaviest snow is expected in northern California, particularly near the Mount Shasta area and higher terrain in western Siskiyou County. Snow will also affect the Cascades, though totals there are forecast to be lower compared to areas farther south.
Snow levels are expected to start near 6,000 feet Saturday evening before dropping to around 4,500 feet by Sunday night as colder air settles into the region. This will increase the likelihood of snow-covered roads along mountain passes and major travel corridors, including portions of Interstate 5, U.S. Highway 97, and nearby mountain highways.
Forecasters indicate that the most intense snowfall is expected Saturday night and Sunday night, with periods of moderate to heavy snow possible at higher elevations. Motorists traveling through mountain areas should be prepared for reduced visibility, slick road surfaces, and potential chain requirements.
By Monday, the weather pattern is expected to shift, leading to decreasing snowfall in the Cascades and gradually improving travel conditions. However, lingering snow and icy patches may persist in shaded or higher-elevation areas during the morning hours.
The National Weather Service advises travelers to monitor forecasts closely and check road conditions before heading out, especially for trips planned more than 24 hours in advance. Those traveling for weekend or early-week plans should allow extra time and carry winter travel supplies.
Snow impacts during overnight hours may particularly affect long-haul drivers, early-morning commuters, and anyone traveling across mountain passes late Saturday through early Monday.
