Nov. 16, 2006 — Meteorologists at the NOAA Climate Prediction Center today released the latest U.S. seasonal outlook and reiterated once again this winter is likely to be warmer than the 30-year norm (1971-2000) over much of the nation, yet cooler than last year's very warm winter season. NOAA's heating degree day forecast for December, January and February projects a 2 percent warmer winter than the 30 year average but about 9 percent cooler than last year.

Meanwhile, a strengthening El Niño event continues to develop in the equatorial Pacific and is likely to continue into spring 2007. "During moderate as well as strong El Niño episodes, an increase in the occurrence of extreme cold days, especially in the Northeast, becomes less likely," said Vernon Kousky, research meteorologist at the NOAA Climate Prediction Center.
