Marine Hail — Niagara River To Hamlin Beach Ny, Lake Ontario

2019-08-17 · near Olcott, Niagara River To Hamlin Beach Ny, Lake Ontario

Wider weather episode

A mid-level shortwave moved east through the eastern Great Lakes, with a trailing weak surface trough and locally grown lake breeze and differential heating boundaries. An initial area of convection moved through the Niagara Frontier to western Lake Ontario in the morning, with additional development down the trough axis over Lake Erie and western New York. The somewhat early arrival of convection limited destabilization to some extent, but we still managed moderate instability by early to mid afternoon with a very moist environment. Low level winds were light, but somewhat better mid-level flow yielded moderate vertical wind shear.
