The NOAA just released an updated outlook for December, January, and February.

Full discussion below:

The December-January-February 2021-2022 temperature outlook depicts elevated odds of above-normal seasonal mean temperatures for most of the southern half of the U.S. and for the eastern third of the nation. The greatest likelihood for above-normal temperatures are located in the Northeast and Southeast. Below normal temperatures are most likely for most of Alaska, the Pacific Northwest, and northern Idaho, Montana, and parts of western North and South Dakota.

For precipitation, above-normal seasonal precipitation amounts are favored for the Pacific Northwest, northern Rockies, Great Lakes, and Ohio Valley. Drier than normal conditions are most likely for the southern tier of the U.S. from California eastward to the Southeast. The greatest likelihood of below-normal precipitation is in southern New Mexico, parts of western Texas, and south Florida.

La Niña conditions persist in the Pacific Ocean and are forecasted to remain through spring 2022. The influence of La Niña contributed substantially to the temperature and precipitation outlooks through the winter months into Spring 2022.
