A strong low and disturbance in the upper levels of the atmosphere moved southeast across southern Quebec, impacting portions of eastern New York and western New England on Wednesday, July 26th.  The disturbance and its associated surface cold front focused scattered strong to severe thunderstorms across eastern New York and western New England during the afternoon hours.  The airmass across the region had ample low level moisture present and became unstable with the heating of the day. The strong disturbance aloft helped intensify the thunderstorms.  The thunderstorm activity evolved into a squall line from the Capital District south and east into the eastern Catskills, mid-Hudson Valley, Taconics, and western New England. Numerous wind damage reports occurred with a microburst just east of the Albany International Airport.
Microburst: A downburst that has an affected outflow area of less than 2.5 miles wide.
Downburst: A strong down draft, initiated by a thunderstorm, that induces an outburst of damaging straight line winds on or near the ground.
