On July 23, 2026, severe thunderstorms caused disruptions to over 7,000 flights across the eastern United States, with at least 2,000 canceled and more than 5,000 delayed. The disruptions affected flights within, into, and out of the region, impacting major airports from Boston to Washington, D.C.
FAA Ground Stops Halt Traffic at Multiple Airports
The Federal Aviation Administration (FAA) issued ground stops at several key airports to manage aircraft movement during hazardous weather conditions. Affected U.S. airports included Baltimore/Washington International Airport (BWI) in Maryland, Boston Logan International Airport (BOS) in Massachusetts, Newark Liberty International Airport (EWR) and Teterboro Airport (TEB) in New Jersey, LaGuardia Airport (LGA) and Westchester
County Airport (HPN) in New York, Philadelphia International Airport (PHL) in Pennsylvania, and both Ronald Reagan Washington National Airport (DCA) and Washington Dulles International Airport (IAD) in Virginia.

Significant Delays at John F. Kennedy Airport
While John F. Kennedy International Airport (JFK) did not have a formal ground stop on July 23, 2026, it experienced an average ground delay of approximately four hours due to the ongoing thunderstorms. In the New York City metropolitan area, nearly 600 departing flights were canceled and over 500 were delayed as operations were severely disrupted.
Storm Causes and Weather Warnings
The flight disruptions were
triggered by a series of severe thunderstorms moving over the eastern U.S. Flood warnings and tornado watches were issued across parts of the Northeast. At least two tornadoes were confirmed, one occurring in northeast Pennsylvania and the other in northern New Jersey. These extreme weather phenomena prompted the FAA to enact ground stops temporarily, restricting aircraft at several airports for safety reasons.
