Weak La Niña Expected to Impact U.S. Weather This Winter

The Climate Prediction Center forecasts a 57% chance of La Niña developing by December, influencing varying weather patterns across the country.

La Niña typically brings cooler, wetter winters to the Pacific Northwest and the Ohio Valley, while the southern U.S. experiences warmer, drier conditions.
Forecasters note a decrease in the probability of La Niña forming, down from 71% to 57%, with expectations of a weak and short-lived event.
Regions like the Great Lakes and parts of New England may see above-average snowfall, while the Pacific Northwest could experience less snow than usual during weak La Niña years.
California, particularly its central and southern parts, might face drier-than-average conditions, though the impact is predicted to be less severe than during stronger La Niña events.
La Niña can affect global agriculture, potentially leading to droughts and impacting food security in vulnerable regions, though this year's weak event may lessen those effects.
