Fast moving cold front to impact our area this afternoon and overnight.
A quick-hitting cold front will move into the area tonight. Snow will begin over the higher elevations above 4500 feet late this evening and continue, heavy at times, overnight as snow levels drop.
Snowfall rates of around 1 inch per hour combined with the potential for gusty winds will result in poor visibility less than one quarter of a mile at times and very hazardous driving conditions.
The heaviest snow will occur in a 3-6 hour period between midnight and 6 am. While snow levels will drop to around 2500 feet by Saturday morning, most of the accumulating snow will be over by then.
The most likely snowfall at both Crater Lake and Diamond Lake is 6-8 inches, with 4-6 inches at Lake of the Woods along Highway 140 and 2-3 inches at Siskiyou Summit on I-5.
Areas to the south and east like Mt. Shasta and areas east of the Cascades will mostly have an inch or less, but some of the higher passes could have 1-3 inches. If you are planning travel through the mountains Saturday morning, be sure to check the latest road conditions before you go.
Conditions should improve by late morning. When driving in ice and snow, take it slow! Make sure to carry chains, food, water, blankets, flashlights, medications, and a fully charged phone when traveling.
