January2011
In a dramatic change from December, little or no precipitation fell in California during January. The dry regime also stretched eastward into the Four Corners states. In contrast, warmth and melting snow accompanied a period of heavy precipitation from the Pacific Northwest to the northern Rockies, leading to some flooding.
Colder-than-normal weather dominated the eastern half of the nation during January, while near- to above-normal temperatures covered most areas from the High Plains westward. Monthly temperatures averaged at least 5°F below normal in parts of the southern Atlantic region and a few locations in the upper Midwest.

Meanwhile, the lowest New Year's Day temperatures on record were noted in Roosevelt, Utah (−31°F); Fort Valley, Arizona (−28°F); and Burns, Oregon (−23°F).
