The winter that wouldn’t quit has showed up again in the Sierra Nevada region of California and Nevada. The fast-moving storm isn’t expected to last long, but it has brought chain controls Tuesday to some trans-Sierra highways. It's also brought unseasonable cold to the mountains while adding to staggering snowfall totals left by an exceptional series of winter storms. The National Weather Services says spring conditions will return later in the week. One resort in the Lake Tahoe region reported 100 mph winds early Tuesday. Another reported temperatures down to 18 degrees. Nearly 74 feet of snow has already been measured at the summit of Mammoth Mountain this season.
