On the evening of May 22nd, a stationary boundary remained draped across northern New York and Vermont. There was enough low-level instability, as well as disturbances along this boundary to produce scattered and training thunderstorms during the evening hours in the Champlain Valley that produced some hail and localized urban flooding in poor drainage locations.
