An upper level disturbance moved through southern New England, providing a focus for a few showers and thunderstorms. Instability was limited somewhat by cloud cover and weak winds at the mid and upper levels of the atmosphere resulted in slow moving storms. The atmosphere was very moist with precipitable water levels around 2 inches, this led to very heavy rainfall with storms that developed. One particular storm became severe over Greenfield and produced a microburst, downing numerous trees
