The winter of 2008 was the coldest in seven years.
Hey Al, I gotcha global warming right heeeere!</Brooklyn accent>
As deliciously reported by the National Oceanic and Atmospheric Administration moments ago (emphasis added, h/t NBer tropicalreport):
In the contiguous United States, the average winter temperature was 33.2°F (0.6°C), which was 0.2°F (0.1°C) above the 20th century average – yet still ranks as the coolest since 2001. It was the 54th coolest winter since national records began in 1895.
Mountains and mountains of snow fell throughout most of the country easing drought conditions in many areas:
- Winter precipitation was much above average from the Midwest to parts of the West, notably Kansas, Colorado and Utah. Although moderate-to-strong La Niña conditions were present in the equatorial Pacific the winter was unique for the above average rain and snowfall in the Southwest, where La Niña typically brings drier-than-average conditions.
- During January alone, 170 inches of snow fell at the Alta ski area near Salt Lake City, Utah, more than twice the normal amount for the month, eclipsing the previous record of 168 inches that fell in 1967. At the end of February, seasonal precipitation for the 2008 Water Year, which began on October 1, 2007, was well above average over much of the West.
- Mountain snowpack exceeded 150 percent of average in large parts of Colorado, New Mexico, Arizona, and Oregon at the end of February. Spring run-off from the above average snowpack in the West is expected to be beneficial in drought plagued areas.
- Record February precipitation in the Northeast helped make the winter the fifth wettest on record for the region. New York had its wettest winter, while Pennsylvania, Connecticut, Vermont, and Colorado to the West, had their second wettest.
- Snowfall was above normal in northern New England, where some locations posted all-time record winter snow totals. Concord, N.H., received 100.1 inches, which was 22.1 inches above the previous record set during the winter of 1886-87. Burlington, Vt., received 103.2 inches, which was 6.3 inches above the previous record set during the winter of 1970-71.
Global temperatures were also the coldest since 2001:
- The combined global land and ocean surface temperature was the 16th warmest on record for the December 2007-February 2008 period (0.58°F/0.32°C above the 20th century mean of 53.8°F/12.1°C). The presence of a moderate-to-strong La Niña contributed to an average temperature that was the coolest since the La Niña episode of 2000-2001.
- While analyses of the causes of the severe winter storms in southern China continues, NOAA Earth System Research Laboratory scientists are focusing on the presence of unusually strong, persistent high pressure over Eastern Europe, combined with low pressure over Southwest Asia. This pattern directed a series of storms across the region, while northerly low level flow introduced cold air from Mongolia. Unusually high water temperatures in the China Sea may have triggered available moisture that enhanced the severity of these storms.
- Record Northern Hemisphere snow cover extent in January was followed by above average snow cover for the month of February. Unusually high temperatures across much of the mid- and high-latitude areas of the Northern Hemisphere in February began reducing the snow cover, and by the end of February, snow cover extent was below average in many parts of the hemisphere.
