The National Weather Service issued its forecast for the winter on Thursday, and most of the U.S. should expect warmer-than-average temperatures, on the assumption that a weak La Niña weather pattern develops in the Pacific. While the lower two-thirds of the U.S., Hawaii, and the northern and western parts of Alaska will be unusually warm, said Mike Halpert of the Climate Prediction Center, there will also be "greater-than-average snowfall around the Great Lakes and in the northern Rockies, with less-than-average snowfall throughout the Mid-Atlantic region" and a dry winter across the south. If the forecasts of a warmer-than-average winter are true, it would be the third one in a row — last winter was the sixth warmest on record, and the one before that the warmest ever recorded, The Washington Post notes.
