The forecast for winter 2013-14, issued by the Climate Prediction Center back in mid-November 2013, called for enhanced probabilities for above normal temperatures and below normal precipitation. Both forecasts were correct with Tucson recording the warmest Winter season on record and the 15th driest Winter on record. The average Winter temperature of 56.9° surpassed the previous record of 56.6° from 1980-81. There were only three distinct cooler than normal periods during the past winter, two in December and one to start off February. Winter temperature extremes ranged from 88° on February 15th to a low of 31° on December 10th. There were only 2 days where the airport recorded daily lows that were of 32° or colder. This is the least amount during winter on record, tied with 1940-41, 1979-80 & 1994-95.

 
Precipitation amounts across the metro area for the winter season, using several sources like rainlog.org, the Pima County Regional Flood Control District gages and CoCoRaHS, generally ranged between 0.50" to 1.50" with heavier amounts mostly on the east side of the metro area. Officially, the International airport recorded 0.84" which is almost two inches below normal and ranks as the 15th driest Winter on record. The airport didn't record measurable rain for 44 consecutive days (December 21st to February 2nd). This ranks as the 16th longest streak during the winter season.
