La Niña Conditions Expected for the Upcoming Winter

The outlook from the Climate Prediction Center for the upcoming winter of 2021-22 is saying that La Niña conditions are expected to persist and likely continue into next spring. During the winter, La Niña typically brings above-average precipitation and colder-than-average temperatures along the northern tier of the U.S., along with below-average precipitation and above-average temperatures across the South. However, other climate patterns, such as the Madden-Julian Oscillation and Arctic Oscillation (AO), can also play a 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 of weeks.
