El Nino to Influence Winter Weather

November 03, 2009

An El Niño in the equatorial Pacific is expected to play a dominant role in the winter weather for the U.S. Temperatures are expected to be warmer than average across most of the western and central U.S. with cooler than average temperatures in the Southeast and mid-Atlantic states.
