Will There Be A Polar Vortex This Year?

According to MNN.com, "Remember in the mid-1990s when we couldn't stop talking about El Niño? Well, we're doing the same thing now with the polar vortex... It could make for a wild winter for much of the Northern Hemisphere in January, particularly for the Eastern United States." Judah Cohen, a climate researcher at Atmospheric and Environmental Research, studies polar vortex conditions and prediction models every day.
