The question is was this really unusual? I checked the Huntington Lake COOP Weather Station at 7,020 feet in the Southern Sierra. The record is from 1914 to the current date. In the 97 year record only three times has it snow more than 20 inches in October. Only ten times did it snow ten inches or more, there were other years with a dusting less than ten inches. Getting 20 inches this early in the year is a bit unusual. As you can see the last time it was in 1939, which was during another cool cycle PDO. Stay tuned, I will check back for the actual snow fall at Huntington Lake.
