Albuquerque had its first “official” freeze of the year this morning, with a low of somewhere around 29 at the airport this morning. At my house in town, we’ve dropped below freezing a bunch of times already (apparently I live in an urban cold island), but the airport is the place with a long and consistent record, so it’s reasonable to compare Nov. 10 with the long term numbers.

The long term average is Oct. 31, but the recent trend, not surprisingly, has been toward later dates. This is a local manifestation of what is known in the scientific community as “global frickin’ warming.”
