A weak area of low pressure traveling along a stationary front, draped across NY and VT, embedded in an unseasonably warm and unstable air mass resulted in a series of thunderstorms that moved across northern New York in the afternoon with a second round during the evening. Some of these thunderstorms produced damaging winds of downed trees and utility lines.
