Episode Narrative A series of upper level disturbances rotated around a vertically stacked low pressure system in the Great Lakes. These provided a focus for showers and thunderstorms to develop across southern New England. Southerly winds drew tropical moisture over the area, resulting in very heavy rain in showers and thunderstorms that developed. In addition, strong winds in the upper levels and 30-40 knots of deep layer shear resulted in wind damage with the strongest of these storms.
Event Narrative A tornadic waterspout over the waters south of Block Island moved northward onto land as a tornado over the southern portion of the island a little before 4pm. On Lakeside Drive, it downed several trees, deck furniture was thrown 100 yards away, and screens were blown off a house. An anemometer at a house on Sand's Pond Road was damaged. Fifty trees were blown down on a farm. Several trees in New Shoreham were downed and there was lawn damage occurred on Chapel Street. Farther to the northeast, there were eyewitness reports of a rotating column that moved steadily across a narrow region just to the west of Jerry's Point. A path of flattened brush 50 feet wide was reported there.
