A lifting warm front across the region brought a hot and humid air mass into the region, leading to maximum heat indices reaching 95 to 98 degrees across some valley locations of eastern New York.
An approaching cold front from the west led to numerous showers and thunderstorms during the afternoon and evening hours. Some of these storms became severe with several reports of downed trees and power lines. A couple trees fell onto homes with another falling onto a camper trailer. No injuries were reported. A funnel cloud was spotted by an observer in Warren County looking northward toward Lake George. A lightning strike hit a structure near Galway, causing a fire. Sporadic power outages occurred as a result of these storms with more than 1,000 National Grid customers without power in Washington County.
