Marine Hail — Upper Niagara River, Lake Erie

2024-07-15 · near Buffalo Harbor, Upper Niagara River, Lake Erie

Wider weather episode

A strong upper-level trough and mesoscale convective vortex (MCV) crossed western and central New York during the afternoon on July 15, 2024. Timing with the MCV corresponded with favorable daytime heating and partly to mostly sunny skies ahead of the system. This resulted in more than 2,000 J/kg of CAPE across much of the region south & southeast of Lake Ontario. Combined with the dynamic nature and the shear associated with the MCV itself, severe thunderstorms developed and moved across the area.
