Winter Outlook: Warmer Than Average for Many, Wetter in the North

Warmer-than-average temperatures are forecast for much of the U.S. this winter according to NOAA’s Climate Prediction Center. Although below-average temperatures are not favored, cold weather is anticipated and some areas could still experience a colder-than-average winter. Wetter-than-average weather is most likely across the Northern Tier of the U.S. during winter, which extends from December through February.

While the El Nino Southern Oscillation (ENSO) climate pattern often influences the winter, neutral conditions are in place this year and expected to persist into the spring. In the absence of El Nino or La Nina, long-term trends become a key predictor for the outlook, while other climate patterns, such as the Madden-Julian Oscillation and Arctic Oscillation (AO), will likely play a larger role in determining winter weather. For example, the AO influences the number of arctic air masses that intrude into the U.S., but its predictability is limited to a couple weeks.

“Without either El Nino or La Nina conditions, short-term climate patterns like the Arctic Oscillation will drive winter weather and could result in large swings in temperature and precipitation,” said Mike Halpert, deputy director of NOAA’s Climate Prediction Center.

This spring saw significant and historic flooding across the central U.S. that impacted nearly 17 million people. However, during the summer and early fall, drought rapidly developed across much of the South, with drought conditions now present across approximately 20% of the country.
