A remarkably warm winter temperature

Climate Central notes that much of the US has had little snow this winter, and some of the Plains states have just had some very high temperatures:

The National Weather Service said on its Sioux Falls, S.D., website that one sign pointing to the unusual nature of the warm weather was the fact that old records were exceeded by huge margins, as much as 17 degrees warmer than previous records, the agency's website states. As noted by the Weather Channel's Twitter account, the high temperature of 61°F in Minot, N.D., — an all-time January record — was the average high temperature in April, according to The Weather Channel.
