The West Coast’s summer has been interrupted by an unusually cold system from the Gulf of Alaska that dropped down through the Pacific Northwest into Northern California. Snow was reported early Saturday on towering Mount Rainier in Washington State. In California, an estimated three inches of snow fell at a national park overnight, causing authorities to close part of a highway. Snow dusted a viewpoint of the Sierra Nevada in California, with more light snow possible around Tioga Pass and higher elevations of Yosemite National Park. That is according to the National Weather Service. August snow has not occurred since 2003 in such Yosemite locations as Tioga Pass.
