A warm front was draped across the region during the late afternoon and early evening hours on Friday, June 13th, while a cold front slowly approached from western New York.
The combination of these fronts allowed repeated rounds of slow moving thunderstorms to move across the Mohawk Valley during the late afternoon and early evening hours.  With above-normal amounts of moisture in place, rain fell very heavily across the region in a short period of time.  This led to flash flooding, with roads being washed out and a few homes being impacted by water in Montgomery County.  By the late evening hours, the fronts crossed through the region and the threat for thunderstorms ended, allowing water to recede.
