...Periods of snow expected to impact Holiday travel through the Cascades and Siskiyous this weekend...
A cold system will drop south from British Columbia Saturday into Sunday, likely resulting in periods of moderate snowfall over the Cascade passes. Snow is expected to begin in the vicinity of Diamond Lake by Saturday afternoon, then spread south through Crater Lake to the far southern Oregon Cascade passes Saturday evening. Snow will then continue through Sunday night.
Saturday through Sunday night, total snow accumulations of 6 to 10 inches are forecast for Highway 138 near Diamond Lake, and Highway 62 near Crater Lake, and 2 to 5 inches are forecast for highways 140 and 66 over the far southern Oregon Cascades. Interstate 5 over Siskiyou Summit could see a couple inches as well.
Confidence in snowfall accumulations is moderate to low due to uncertainty in the amount of moisture with the system as it pushes through the area.
Travelers through the Cascades this weekend should take extra precautions to prepare for wintry conditions and snow covered roads. Stay tuned for forecast updates, and check state transportation departments for Road conditions prior to travel.
