February 9 marked the average last date that Fargo Moorhead records a high temperature below zero. So far this season we have recorded six such days with the last occurrence being on January 8. If by chance we do not observe another day with temperatures remaining below zero for a high, it would be the earliest such last occurrence since the winter of 2001-2002 when we managed to go through the entire winter without a maximum temperature below zero.
Last year we recorded 14 days with a high temperature below zero, including one of the latest on record when we had a high of -1 degree on March 11, 2009. The record for the latest below zero high was set on March 24, 1974.
So although the odds favor us not observing a negative high temperature until next winter, if we do, it will likely come after a fresh snowfall and a day with a light wind.
