Winter Storm To Dump Snow, Icy Mix Across West

December 5, 2022
UPDATED By WeatherBug Meteorologists
Parts of the West will have fresh snow to worry about this week as a few wintry disturbances sweep through. Lighter snowfall totals and an icy mix will also blanket the interior Northwest and into Montana as a storm system gradaully moves inland from the Pacfic.

A moisture-laden, slow-moving storm will squeeze out snow across the northern Sierra Nevada through early Tuesday before weakening and exiting into southern California and Nevada. At first, snowfall will be heaviest at pass level today before falling from 8,000 feet to 4,000 feet. These bursts of heavy snow will leave 1 to 4 feet of accumulation above 7,000 feet.

Six inches to a foot is forecast between 4,000 and 7,000 feet, including at lake level in Lake Tahoe, Calif. Winter Weather Advisories are in place for northern California, parts of western Washington and Oregon, Idaho, Montana and Wyoming, as well as northern Utah, where snow amounts between 4 and 8 inches will be possible. Winter Storm Warnings are in place across the Sierra Nevada and in California, including Mount Shasta. Gusty winds exceeding 40 mph will lead to extremely difficult travel and could cause tree damage.

The storm’s moisture will penetrate further inland, covering interior Oregon and southeastern Washington to the Idaho, Montana Bitterroot Ranges this morning. The southern Idaho valley floors south of Boise will receive an inch or two of snowfall with up to one-tenth inch of freezing rain accumulation. Like California, travel will become difficult along parts of Interstates 15, 84, 90 and 94.

It’s never too early to have a supply kit packed in case of inclement weather. A simple kit including a weather radio, water, blankets, batteries and non-perishable food items will go a long way in the event of a power outage. It’s always best to avoid travel in rough weather as the roads will be dangerous.
