January's weather was a case of "polar" opposites across the U.S. Despite the now-infamous polar vortex and a seemingly endless parade of snow and cold, the USA as a whole was only slightly cooler than average in January, according to a new summary of the month's weather released Thursday by the National Climatic Data Center (NCDC). "The warm temperatures in the West counterbalanced the cold in the East, resulting in an overall monthly temperature slightly below average," the report noted. The national temperature for January was 30.3 degrees, a mere one-tenth of a degree colder than the 20th-century national January average of 30.4 degrees. less
