Episode Narrative A significant severe weather event occurred across east central New York and adjacent western New England, including Litchfield County on Thursday June 9th. A very warm and humid air mass was in place across the region on the morning of June 9th. A cold front was positioned well to the north and west of the region, toward the Upper Great Lakes. However, a well-defined pre-frontal trough marched across Litchfield County late in the afternoon. This pre-frontal trough showed up well in observational data, with an abrupt wind shift to the northwest and a sharp drop in dew points. The pre-frontal trough triggered convection, first as a series of discrete storms developing into a broken line, which eventually evolved into an organized line of severe storms known as a severe quasi-linear-convective-system, QLCS. Initially when the storms were discrete, hail was the main threat. Once the QLCS developed, damaging winds were the main threat. The severe storms resulted in numerous power outages with the large hail denting vehicles.
Event Narrative A National Weather Service Storm Survey Team confirmed a brief tornado touchdown on Great Hollow Road within a greater area of straight line wind damage consistent with a microburst.
