2015 was Atlanta’s Warmest Christmas on Record
Results of My Forecast Posted on December 23rd
On December 23rd, I predicted that records would be tied or broken each day from Christmas Eve through December 27th (4 days in a row). As of 5 am, Sunday 12/27, the forecast has been a success. My median forecast error for the high temperatures was 1 degree; the median error for overnight low was 2 degrees.
One high temperature record was tied (72º on December 24, 2015 tied the previous set in 1984). On December 25th, Atlanta recorded a high temperature of 75ºF, breaking the previous record of 72º that stood for 28 years (set in 1987) and making Christmas 2015 Atlanta’s warmest Christmas on record.
On Sunday, December 27, Atlanta shattered yet another record. The high temperature was 75º, breaking the previous record of 71º set in 1982. Even more impressive was the morning low of 65º which obliterated the previous record for the warmest low temperature on this date (previous record was 58º set in 1982); further, it is now tied with the 2nd-warmest low temperature ever recorded during the entire month of December!
