2019-2020 Winter Outlook

October 17, 2019,  – Forecasters at NOAA’s Climate Prediction Center released the 2019 U.S. Winter Outlook today.

“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.

“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

The 2019 U.S. Winter Outlook (December through February):

Precipitation

  • Wetter-than-average conditions are most likely in Alaska and Hawaii this winter, along with portions of the Northern Plains, Upper Mississippi Valley, the Great Lakes and parts of the Mid-Atlantic and Northeast.

  • Drier-than-average conditions are most likely for Louisiana, parts of Texas, Mississippi, Arkansas and Oklahoma as well areas of northern and central California.

  • The remainder of the U.S. falls into the category of equal chances for below-, near-, or above-average precipitation.

 

Temperature

  • The greatest likelihood for warmer-than-normal conditions are in Alaska and Hawaii, with more modest probabilities for above-average temperatures spanning large parts of the remaining lower 48 from the West across the South and up the eastern seaboard.

  • The Northern Plains, Upper Mississippi Valley, and the western Great Lakes have equal chances for below-, near- or above-average temperatures.

  • No part of the U.S. is favored to have below-average temperatures this winter.
