August 16, 2012 – NEW YORK -After
a 2011-2012 winter that saw little snow, the mid-Atlantic and southern
New England states will get a snow dump this winter, forecasters say.
Above-normal snowfall during winter 2012-2013 is forecast for the major
I-95 cities including New York, Philadelphia, Baltimore and Washington, AccuWeather.com
reported Wednesday. “The I-95 cities could get hit pretty good,”
forecaster Paul Pastelok said. “It’s a matter of getting the cold to
phase in with the huge systems that we are going to see coming out of
the southern branch of the jet stream this year.” The presence — and
strength — of El Nino conditions in the Pacific Ocean are used to
project how active the winter season will be, forecasters said. El Nino
warming of ocean water and the air above it causes weather patterns to
change globally, and El Nino winters feature a strong southern branch of
the jet stream across the United States, AccuWeather.com said. When the
strong southern jet stream phases with the northern branch of the jet
stream, meteorologists said, big storms can hit the east coast. –TD
