With less than two days until a potential major winter storm in the Northeast, meteorologists are grappling with starkly different forecasts from the American GFS and European weather models. The GFS is predicting a near-record blizzard, while the European model foresees a much weaker storm, leaving forecasters uncertain about the storm's intensity and track.

Why it matters

Accurate forecasting is crucial for the densely populated Northeast corridor, where a major snowstorm could cost hundreds of millions of dollars in preparation and response. The disagreement between the two leading weather models highlights the challenges forecasters face in reconciling conflicting data and providing the public with clear, actionable information.

The details

The differences between the GFS and European models stem from how they depict subtle shifts in atmospheric features like energy from Canada, the southern jet stream, and high pressure over the Rockies. These small variations can mean the difference between a paralyzing blizzard and light snowfall. Meteorologists are trying to avoid getting caught up in the 'model battle' and instead focus on communicating the potential impacts and uncertainties to the public.

  • The storm is expected to start on Sunday.
  • Forecasters have less than 48 hours until the storm's arrival.

The players

Global Forecast System (GFS)

An American computer model that is predicting a near-record snowstorm for the Mid-Atlantic and Northeast.

European model

A leading weather model that is forecasting a much weaker storm tracking farther from the coast, bringing lighter snow.

What they’re saying

“We look at every model, every ensemble system available to us, and usually the answer is somewhere in between. We need to use all the guidance available to come up with a good message about the storm. And that's the main thing, is coming up a good message versus the specific snow amounts.”

— Cody Snell, Meteorologist, NOAA Weather Prediction Center

“Clearly you want certainty; you want all the models to agree, and you can speak with confidence that this is the scenario that's going to occur. But whenever there's differences, especially with this population in play along the northeast, you just have to take into account all the possibilities.”

— Cody Snell, Meteorologist, NOAA Weather Prediction Center

What’s next

Meteorologists will continue to monitor the situation and provide updates as the storm approaches. The National Weather Service and local forecasters will work to communicate the potential impacts and uncertainties to the public.

The takeaway

This storm highlights the challenges forecasters face when weather models disagree, especially for high-impact events in densely populated areas. Effective communication of the potential range of outcomes and uncertainties is crucial for helping the public prepare appropriately.
