The episode as NWS ALY wrote it up.
Early in the day on July 25, weak low pressure and its associated cold front were north of the St Lawrence Valley. The cold front moved slowly east and south while weakening. During the evening, thunderstorms formed in the unstable mass over north-central New York. A few thunderstorms became severe, blowing down trees in several locations in the western Mohawk Valley. In addition, heavy rainfall produced flash flooding in Middleville.

MODEL TRENDS CONTINUE TO SAG FRONTAL BOUNDARY ACROSS THE GREAT LAKES REGION AND THE NORTHEAST LATE IN THE WEEK AND OVER THE WEEKEND...BUT AT BIT SLOWER OF A PACE.
