2013-14 December-February winter temperatures and their departure from average at Duluth, Minnesota - Airport location.

December 2013:  5.2 degrees
Departure:  -9.6 degrees below average

January 2014:  1.6 degrees
Departure:  -8.6 degrees below average

February 2014:  5.3 degrees
Departure:  -9.8 degrees below average

2014-15 December-February winter temperatures and their departure from average at Duluth, Minnesota - Airport location.  Note:  February data is thru the 23rd.

December 2014:  22.1 degrees
Departure:  +7.2 degrees above average

January 2015:  12.7 degrees
Departure:  +2.5 degrees above average

February 2015:  5.3 degrees
Departure:  -9.0 degrees below average

Note:  Can't really compare this winter to last winter when looking at temperature data.  The cold last winter was just so persistent.  This winter has had numerous thaws which have been quite significant.  Yes, this month has been a cold one, but outside of February the winter of 2014-15 has not been very cold.  I do find it somewhat interesting though that this month has the similar temperature that we saw all of February 2014 (5.3 degrees)  I think there's a decent chance we end up colder this February compared to last February, so that is pretty epic considering how damn cold it was last winter.
