More than 7,000 flights were impacted by severe thunderstorms across the eastern United States on Tuesday, July 21, 2026. The weather caused over 2,000 cancellations and upwards of 5,000 delays at airports serving the New York City area, Boston, Philadelphia, and Washington, D.C.
Major Airports Face FAA Ground Stops and Delays
The Federal Aviation Administration issued ground stops at multiple airports due to the thunderstorms. Affected 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)

Traveler Impact and Ongoing Disruptions
The combination of cancellations, ground stops, and delays left thousands of passengers dealing with disrupted travel plans Tuesday. FAA ground stops limited aircraft movement at numerous major airports, compounding delays.
