As the mid-Atlantic cleans up from over two feet of snowfall in some areas, and begins preparation for another major storm this week, many are left asking, "Why so many major storms?"
No single factor is responsible for this winter's wicked nature, but several elements working together have produced monster storms this season.
"The blocking pattern in the jet stream is creating access to extremely cold air," said AccuWeather.com's Chief Meteorologist and Expert Long Range Forecaster Joe Bastardi.
The normal jet steam patten flows west to east, but when warm ocean air flows northward, harsh, cold air is pushed from northern Canada into the U.S.
When the normal pattern gets dislodged by warm Pacific air, storms intensify and erupt.
The storm track that continues to develop is bringing storms to the mid-Atlantic, rather than directly along the Eastern Seaboard.
The El Nino pattern over the last several weeks has been very strong, prompting many major blizzards for the mid-Atlantic region. This pattern should fade by the end of winter.
As the eastern half of the U.S. is seeing more snowfall, Southeastern Canada is suffering a major lack in snow. The 2010 Winter Olympic Games in Vancouver is also suffering from warm, dry conditions as a result.
Major cities, Philadelphia, Pittsburgh, Baltimore and Washington, D.C., have been hit the worst by this winter's wrath, and Bastardi is telling people to get used to this weather pattern.
"Winters will be going back to what was seen in the '60s and '70s, major storm after major storm," said Bastardi.
Bastardi released this winter's forecast in July, pinpointing that the Northeast and mid-Atlantic states would see a cold winter with snowfall well above-average.
The heart of this winter was to be centered over the area from Southern New England to Washington, D.C.
The Washington, D.C. Metro area has already been pummeled by two storms, with a current snowfall total of 45.1 inches recorded at Reagan International Airport.
The record winter snowfall total is 54.4 inches for the area, which will likely be broken later this week when the region could see another 6 to 12 inches.
