As several storms roll in, snow is expected to fall at elevations above 1500 feet on Friday, slightly higher than the elevation of Medford. High elevation passes like Siskiyou Summit on Interstate 5 at the Oregon-California border are expected to get snow through the weekend. The Cascades could get 6-12 inches of snow and Highway 97 east of the Cascades could get six inches near Chemult, according to the National Weather Service.
Even I-5 north from Grants Pass to Canyonville could get 4-8 inches of snow starting Friday afternoon, according to Ryan Sandler, a meteorologist with the National Weather Service office in Medford.
Holiday travelers should go before Friday afternoon if possible, he says.
鈥淚f you鈥檙e leaving Friday morning you might be okay. But if you鈥檝e got to come back Friday late in the day or Friday evening Christmas Eve, there could be winter weather even in the lower elevations between the valleys,鈥 Sandler says.
On Thursday evening Gov. Kate Brown issued a state of emergency for severe winter weather through Jan. 3.
"This weather is expected to bring heavy snow and sustained temperatures below freezing, resulting in critical transportation failures and disruptions to power and communications infrastructure," Brown's office wrote in a statement.
Also on Thursday, the Oregon Office of Emergency Management issued a warning about snowy and windy conditions over the next 7-10 days that could result in power outages and dangerous driving conditions.
A second storm could make travel difficult on Sunday, when many people are heading home after Christmas.
鈥淚t looks like there鈥檚 going to be a lot of snow around, especially in the mountains, but even in the valleys there could be snow on Sunday,鈥 Sandler says. 鈥淪o, that鈥檚 what we鈥檙e really looking at for people traveling back. On Sunday it could be a lot of winter weather and very messy.鈥
Drivers should carry chains, use four-wheel drive, if possible, and be prepared for delays over the holiday weekend.
