Dec 032011
 

It blows me away when we have record-breaking 6 inch snow falls, in December, in Flagstaff. That’s what happened on Thursday. I’m not sure what the old record was, but I think I remember seeing about 4.5 inches. The record below is goofy because it reports a record in 2011, but always says the snowfall data is missing. Most of us can probably remember digging out of bigger snowfalls in late  November and early December. This shows how short our climate record really is. We don’t have a good sense for what our boundaries truly are.
