An email arrived in the weather center asking what day of the year has the largest temperature range from the record low to the record high. The recorded low on January 8, 1887 was -48 degrees. Thirteen years later, on January 8, 1900, the recorded high temperature reached 50 degrees.
That difference of 98 degrees still stands as the greatest range between a record high and low for any date in Fargo Moorhead. In second place is March 18. On March 18, 2012 the high reached 78 degrees with the record low for that date being -19 degrees observed in both 1883 and in 1923 for a difference of 97 degrees from record high to record low. A snow free March as we learned in 2012 can be very mild, a snow covered March like last year and so far this year, can be bitterly cold.
Those snow variations in combination with a higher sun angle this time of year make March the month with most of the extreme record differences observed in this area.
