Since records began in 1881, the average number of days with a low temperature below zero during the cold season in Fargo Moorhead is 48 days. With winter only about one-half done, the airport has already recorded 37 such days.
Last year the metro recorded 43 below zero days and during the very mild winter of 2011-2012 the temperature dropped below zero on just 16 days all winter. As a reference, our recently completed December had more below zero days than that entire winter. Looking forward, we could easily record as many below zero days by the end of this month as we did all of last winter with another six weeks of negative potential left after this month. Although patterns can change quickly, it appears this winter may rival the 61 below zero days recorded back during the winter of 2008-2009.
Excluded data from the 1880s, the highest number of negative days in a cold season was set during the winter of 1964-1965 with 76 such days.
