The temperature in Minneapolis didn't fall to zero degrees this winter until Jan. 12. On Jan. 5., the daytime high in Rapid City, S.D. (a record-setting 71 degrees), was higher than in balmy Miami (69 degrees). And just a couple of days before New Year's, visitors to Park City, Utah, skied on man-made snow and dined al fresco — without their parkas.
Throughout the continental United States, it's been a very warm winter.
