Conversely, the snowpack was much above average in Arizona, New Mexico, and southern Utah. Some individual SNOTEL stations in the northern Rockies had early April snow water equivalent in the driest fifth percentile of the historical record (95 percent of the years for this date were wetter). The pattern was evident in the high-elevation station ( SNOTEL) network, especially in maps of the end-of-March snowpack and snow water content. Mountain snowpack in the Pacific Northwest was less than 25 percent of normal in several locations. During the 2009–2010 Cold Season, the West generally experienced much–below average snowpacks. The annual snowpack typically reaches its maximum values at the end of March. The total annual water budget for agriculture and human use in the mountainous West is based upon the amount of snow melt that will occur in spring and is proportional to the amount of snow on the ground. Winter and spring mountain snowpack provide a crucial water source across much of the western United States. The low spring snow cover extent was driven by anomalously warm conditions over the regions which had experienced the heavy snow during the December–February period. As the season transitioned into spring, conditions were almost the complete opposite of the winter, with low snow cover extents reported across the United States during April (8 th smallest) and May (10 th smallest). More information on the 2009–2010 winter can be found in the 2009–2010 Cold Season Special Report. had snow on the ground, including Florida and Hawaii. A far–reaching storm the second week of February brought snow to the Deep South, and every state in the U.S. Highs in the lower 40’s each day, with partly cloudy to mostly sunny skies. Quiet weather for Wednesday, Thursday, and Friday upcoming. January was 6 th largest and February 3 rd largest. Tuesday morning could feature some light snow, then skies will be mostly cloudy. Persistent cold and snow across much of the country during January and February was associated with those months ranking in their top ten largest snow cover extents for the U.S. This was partially due to snow falling across the Southern Plains, Gulf Coast, and the Southeast - regions which do not typically receive much December snowfall. According to 44 years of satellite data analyzed by the NOAA supported, Rutgers Global Snow Lab, a new monthly snow cover extent record was set during December 2009. Here are the latest snowfall totals from the National Weather Service, Rob. Long–standing monthly and seasonal snowfall records were shattered and record cold temperatures were set over the eastern two-thirds of the nation. BOSTON (CBS) - Massachusetts had its first blizzard in four years Saturday. Much of the United States experienced a record breaking 2009–2010 winter.
