The airmass across east central New York became moderately unstable during the afternoon of Wednesday July 6th, with daytime heating and an increase in low level moisture. With the approach of a disturbance in the upper levels of the atmosphere and the presence of a pre-frontal trough, convection fired up across the area with mainly damaging winds occurring with the severe thunderstorms. There were a few reports of large hail.
Pre-frontal trough: An elongated area of relatively low pressure preceding a cold front that is usually associated with a shift in wind direction.
