What is La Niña? A Northeastern expert explains how the weather pattern may impact your winter plans

The La Niña event forecast for this winter may deliver more snow than usual to the Northwestern U.S. and dry, warm weather to the South.

“It just changes the probabilities of having a warmer or colder, wetter or drier, winter than usual – depending on what region you are in.”
