This month has brought some dramatic temperature changes to the area. One of most interesting to me has been the extreme range in low temperatures observed. Back on January 2 the official low in Fargo Moorhead was -33° which was a record for that date. Then three weeks later, on January 23, the official low was 33° above zero. That was also a record, but this time a record high minimum for that date.
So during this month our low temperatures have varied by 66° which is the 2nd highest such difference in our record books for this month. The greatest difference in minimum temperatures in January occurred in 1892 when the range was 67°. That year the lowest minimum temperature was -37° and the highest minimum was 30°.
The all-time record dates back to March of 1964 which experienced a minimum low temperature of -22° with a high minimum of 50° for a monthly difference of 72°.
