Cold weather stats
Source: National Weather Service Duluth, Minnesota
Today February 25 marks the 62nd day this winter with a sub-zero low temperature at Duluth, MN. The unofficial end to winter 2013-14 is March 1, by then we should get to 65 days. By the way we already shattered the previous all-time record which was 59 days with a sub-zero low temperature which occurred in 1958-59, 1916-17, and 1874-75.
Going into Today, Duluth is just 0.2 degrees shy of tying the all-time coldest winter on record which is 3.7 degrees in 1874-75. The average temperature so far this winter (2013-14) is 3.9 degrees. Note: When all is said and done I do think this winter will end up as being the coldest ever in the Twin Ports.
International Falls stats:
67 days so far this winter with a sub-zero low temperature. The record is 70 days set in 1977-78. With below zero low temperatures expected the rest of this week, I’Falls should tie the all-time record of 70 days.
4th coldest winter on record through February 24 with an average temperature of -2.4 degrees. The coldest winter on record is -3.9 degrees which occurred in 1916-17.
