Despite this week’s chill, last month was quite warm — the sixth warmest November on record for Tucson, with an average temperature of 64 degrees.

Fall 2016 — defined by the meteorologists as September through November — is the warmest fall on record, with an average temperature of 74 degrees.

November temperatures had threatened to top the record books until a Pacific weather system brought cold air, rain and mountain snow to the region on the last four days of the month, according to the monthly climate report compiled by John Glueck, meteorologist with the National Weather Service in Tucson.

Glueck said Tucson is on track to record its second warmest year on record. To date, the area’s average is 73.6 degrees, just behind the 73.9-degree pace set in 2014.

This week’s cold weather, which brought freezing temperatures to parts of the region, will be moving out, with highs reaching the upper 60s by Sunday or Monday, said Chris Rasmussen of the Weather Service office in Tucson.

Rasmussen said another cold-air system will be “diving down in the middle of next week.”
