Medford, Oregon – A prolonged winter storm is set to bring significant mountain snowfall to parts of southern Oregon and northern California this weekend, with the most intense conditions expected from Saturday night through Sunday night.
According to the National Weather Service office in Medford, heavy snow will focus on higher elevations of the southern Oregon Cascades and northern California mountains, particularly around the Mount Shasta region and western Siskiyou County. These areas are expected to see the greatest accumulations, with totals potentially reaching well into the double digits at higher elevations.
Heaviest Snow Targets High Terrain
Forecasters say snow levels will start relatively high, near 6,000 feet, early in the event. As colder air gradually moves in, snow levels are expected to drop to around 4,500 feet by late Sunday into Monday. This lowering snow line increases the risk of snow impacting additional mountain passes that may initially see rain or mixed precipitation.
The most intense snowfall periods are forecast during two windows: Saturday night into early Sunday, and again Sunday night. During these times, snowfall rates could be heavy enough to significantly reduce visibility and quickly cover roadways.
Travel Impacts Likely Through the Weekend
Hazardous travel conditions are expected across mountain routes in both southern Oregon and northern California. Chain requirements are likely on higher passes, and drivers should anticipate snow-covered roads, slick conditions, and possible delays—especially overnight and during early morning hours when snowfall rates peak.
While areas farther north in the Oregon Cascades will still see snow, the National Weather Service notes that accumulations there should be lighter compared to regions farther south. By Monday, snowfall across much of the Cascades is expected to gradually taper as the overall weather pattern shifts.
What Residents and Travelers Should Do
Motorists planning travel through mountain areas are urged to prepare for winter driving conditions. This includes carrying chains where required, allowing extra travel time, and checking road conditions before departure. Even experienced drivers may encounter rapidly changing conditions as snow levels fluctuate throughout the event.
Residents in affected regions should continue to monitor forecast updates, winter weather advisories, and road reports as the storm evolves. Conditions may change quickly, particularly as colder air settles in and snow spreads to lower elevations late in the weekend.
