Winter 2011/2012 Statewide Temperature Ranks
Statewide precipitation totals were mixed during the winter season. The western states were particularly dry with California having its second driest winter on record at 7.82 inches below average. Montana was eighth driest, and Oregon and Idaho were both tenth driest for the season. Drier-than-average conditions were also present across the Northern Plains, Southeast, and Northeast. Above-average precipitation occurred in the central United States, from the Ohio Valley into the Southern Plains.
The warm and dry conditions during the 2011-2012 winter season limited snowfall for many locations. According to data from the Rutgers Global Snow Lab, snow cover extent during winter was approximately 237,000 square miles below the 1981-2010 average — the third smallest winter snow cover footprint in the 46-year satellite record. Snowpack was particularly limited across parts of the West, where parts of California, Nevada, and Arizona had snowpack less than half of average.http://www.ncdc.noaa.gov/sotc/
