Another storm will bring moderate to heavy snow to the Cascades Thursday through Sunday evening. Snow could reach the valley floors and the Roseburg area early Friday morning before turning to rain later in the morning. Main impacts to Roseburg will be heavy rains on Saturday and Sunday, with 2.3 inches of rain expected to fall. Deer Creek in Roseburg, known for its rapid response to rainfall, is expected to rise above flood stage late Saturday night into Sunday morning, March 15-16, 2025. Diamond Lake could see 4-6 inches of snow by Saturday morning, and another 4-6 inches between Saturday afternoon and Sunday evening. Crater Lake could receive up to 2 feet of snow by Saturday morning and another 2 feet from Saturday through Sunday evening. Here is a summary of the upcoming weather system from the NWS in Medford: A fast-moving weather disturbance will bring light to moderate precipitation to the area from late tonight through Friday, March 14, 2025. Initially, snow levels will be low, around 1,000-1,500 feet, potentially causing wet snow in west side valleys Friday morning. However, due to recent warmer weather, most roads and paved surfaces at these lower elevations are expected to remain wet rather than snowy. A Winter Weather Advisory has been issued for areas above 1,500 feet, where trace to 2 inches of snow accumulation is possible. This includes lower I-5 passes south of Roseburg (e.g., Camas Mountain, Hayes Hill), as well as Jacksonville Hill, Prospect, and higher areas above Medford and Ashland. Snow levels are expected to rise to 3,000-3,500 feet by Friday afternoon. Winter Storm Warnings have been issued for the Cascades, Siskiyous, and much of Siskiyou County above 2,000 feet, including the Mt. Shasta region. In Siskiyou County, the warning lasts through Friday evening, with the heaviest snow expected between 5 AM and 11 AM PDT, potentially accumulating at rates up to 1 inch per hour. Additional Winter Weather Advisories have been issued for the Shasta Valley and the East Side. The Winter Storm Warning for the Cascades and Siskiyous has been extended through the weekend of March 15-16, 2025, due to multiple periods of moderate to heavy snow with little break. Significant snowfall is expected in the mountains, with 1-2 feet of accumulation above 4,500 feet and up to 4 feet around Crater Lake. For Siskiyou Summit, the primary impact period will align with the Mt. Shasta region, occurring late tonight into Friday morning, March 14, with 3-6 inches of snow possible. Snow levels will gradually rise over the weekend, potentially reaching or exceeding 5,000 feet on Sunday, before dropping back to around 3,000 feet by Monday morning, March 17. - NWS in Medford
