The remarkable Post-Christmas blizzard of 2010 has ended for the United States, as the storm has trekked northeastward into Canada. The blizzard dropped epic amounts of snow during its rampage up the U.S. Northeast coast Sunday and Monday, with an incredible 32" falling in Rahway, New Jersey, about 15 miles southwest of New York City. The highest populated areas of New Jersey received over two feet of snow, including the Newark Airport, which received 24.1". Snowfall amounts were slightly lower across New York City. The blizzard of 2010 dumped 20.0" inches on New York City's Central Park, making it the 6th largest snowstorm for the city in recorded history, and the second top-ten snowstorm this year. Remarkably, New York City has had four of its top-ten snowfalls in the past decade (highlighted in the list below.) According to the National Weather Service, the top ten snowstorms on record for New York City's Central Park since 1869 should now read:
1) 26.9" Feb 11-12, 2006
2) 26.4" Dec 26-27, 1947
3) 21.0" Mar 12-14, 1888
4) 20.8" Feb 25-26, 2010
5) 20.2" Jan 7-8, 1996
6) 20.0" Dec 26-27, 2010
7) 19.8" Feb 16-17, 2003
8) 18.1" Mar 7-8, 1941
9) 17.7" Feb 5-7, 1978
10) 17.6" Feb 11-12, 1983
Newark's 24.2" was one of that city's top-ten snowstorms of all-time, and the 20.1" that fell on Atlantic City, NJ was the city's second largest snowfall in history. Atlantic City's three biggest snowstorms have all occurred in the past ten years:
1) 21.6" Feb 15-18, 2003
2) 20.1" Dec 26-27, 2010
3) 18.2" Feb 5-6, 2010
Philadelphia, PA picked up 12.4", the city's fourth one-foot plus snowstorm in just over a year--a remarkable string of storms, considering the city has had just 24 such snowfalls in history, since 1884. According to phillyweather.net, the latest snowstorm brought Philadelphia's 2010 snowfall for the calendar year to 67.3", breaking the mark for snowiest year ever (previous record: 57.0" in 1978.)

An unusual number of top-ten snowstorms for the Northeast in recent years
The Northeast has seen an inordinate number of top-ten snowstorms in the past ten years, raising the question of whether this is due to random chance or a change in the climate. A study by Houston and Changnon (2009) on the top ten heaviest snows on record for each of 121 major U.S. cities showed no upward or downward trend in these very heaviest snowstorms during the period 1948 - 2001. It would be interesting to see if they repeated their study using data from the past decade if the answer would change. As I stated in my blog post, The United States of Snow in February, bigger snowstorms are not an indication that global warming is not occurring. The old adage, "it's too cold to snow", has some truth to it, and there is research supporting the idea that the average climate in the U.S. is colder than optimal to support the heaviest snowstorms. For example, Changnon et al. (2006) found that for the contiguous U.S. between 1900 - 2001, 61% - 80% of all heavy snowstorms of 6+ inches occurred during winters with above normal temperatures. The authors also found that 61% - 85% of all heavy snowstorms of 6+ inches occurred during winters that were wetter than average. The authors conclude, "a future with wetter and warmer winters, which is one outcome expected (National Assessment Synthesis Team 2001), will bring more heavy snowstorms of 6+ inches than in 1901 - 2000." The authors found that over the U.S. as a whole, there had been a slight but significant increase in heavy snowstorms of 6+ inches than in 1901 - 2000. If the climate continues to warm, we should expect an increase in heavy snow events for a few decades, until the climate grows so warm that we pass the point where winter temperatures are at the optimum for heavy snow events.

NYC never called a Snow Emergency. And like a hurricane, it's the areas NOT being heard from that should raise alarm bells. And again I note the discord in reporting. CNN/ABC are on it. MSNBC/FOX/CBS have other things to talk about.
And like a hurricane, it's the areas NOT being heard from that should raise alarm bells. And the Gov. of New Jersey stayed in Florida on vacation. How nice!
He never came back!? His career is over. Like bush43 right now with Hannity doing historical revision on 9-11. History is not kind to public epic fail. 8D
I'm serious. right now FOX is doing a Huxley/Orwell with bush43. who dares call successful treason by it's real name. He was reading the Pet Goat upside down. 8D
New York City’s emergency system was “overwhelmed” by the Dec. 26 blizzard that dumped 20 inches of snow, leaving vehicles marooned and ambulances unable to reach the sick, injured and dying, Mayor Michael Bloomberg said. “You can give us any grade you want,” Bloomberg told reporters at a press conference at a Bronx hardware store today. “We did not do as good a job as we wanted to do, or as the city has the right to expect.” Expect this from now on. As you could tell which reporters had skin in the game. Still no answers. 8D
