La Niña to Shape U.S. Winter Weather Patterns for 2024-25

The anticipated weak La Niña could bring colder conditions to the Northwest and drier weather to the South.

La Niña, characterized by cooler Pacific Ocean temperatures, is expected to influence U.S. weather through early 2025.
Federal forecasters predict a 60% chance of La Niña conditions emerging by the end of November.
The Northwest and Great Lakes regions may experience increased snowfall, while the Southern U.S. could see warmer, drier conditions.
Experts caution that La Niña's effects vary and are not deterministic for specific weather events.
The Climate Prediction Center notes that this La Niña is likely to be weak, potentially reducing typical winter impacts.
