We are halfway through winter and after an exceptionally warm start, North America’s winter is transitioning toward more predictable patterns with La Niña.

La Niña is usually associated with drier conditions across the southern part of the U.S. and wetter conditions to the north. This reflects how La Niña is associated with a more poleward-shifted jet stream that deflects the storm tracks to the north (both Emily and Tom have written some nice explainers).

La Niña has arrived and is likely to be impacting the winter season, including how much snow and rain New England might see before the start of spring.

NOAA has declared that a La Niña is underway. This cool weather event is likely to be shorter and weaker than usual, but will still affect global weather and climate.

If you live in a city where a meteorologist mentions an "La Niña" or "El Niño" it is important to distinguish the difference between the two.

The long-awaited La Niña has finally arrived but it is weak and meteorologists say it's unlikely to cause as many weather problems as usual. Experts have been expecting the arrival of the climate phenomenon since last spring but finally,

La Niña has finally materialized. Here’s what that means for South Carolina weather and snow during the rest of the winter.

La Niña conditions finally arrived last month, and for us powder hounds, that’s big news. The tropics might be thousands of miles away, but shifts in the Pacific’s sea surface temperatures can influence the jet stream, storm tracks, and ultimately how ...

After a bit of a waiting game, La Niña conditions have finally materialized, characterized by below-average ocean temperatures in the Pacific, according to the Climate Prediction Center. A statement issued last week says there is a 59% chance that La ...

After months of waiting, La Niña conditions finally emerged in the tropical Pacific last month, according to the National Weather Service Climate Prediction Center.

The Climate Prediction Center says that sea-surface temperature data in the Pacific Ocean indicates the emergence of a "weak" La Niña.

We are halfway through winter and after an exceptionally warm start, North America’s winter is transitioning toward more predictable patterns with La Niña. As La Niña’s presence becomes ...
