GFS Predicts Major Northeast Snowstorm Over New York City
|
7.2
Two days before New York's biggest snowstorm in a decade began, the U.S. Global Forecast System (GFS) consistently forecast heavy snowfall while newer AI-based models showed lower confidence. The National Weather Service reported nearly 20 inches in Central Park and more than two feet on Long Island, with over 500,000 outages and about 10,000 flights canceled. Forecasters say AI still struggles with fast-moving nor'easters, affecting warning timing.
