An unusually hot and humid air mass was situated over eastern New York during the afternoon on Thursday, September 3rd.  With temperatures in the upper 80s F, the atmosphere became quite unstable.  With no large-scale weather systems close enough to produce widespread activity, thunderstorms were fairly isolated across the region. However, one of these thunderstorms became severe, as it moved southward out of Saratoga County into Albany County during the mid-afternoon hours.  This thunderstorm produced heavy rainfall and gusty winds over the populated Capital Region, causing tree damage in the Colonie area.  Some of these trees fell on cars and power lines, causing power outages across the region.
