Severe thunderstorms produced significant wind damage throughout most of Massachusetts.The storms first affected the western third of the state by late afternoon, where there were many reports of downed trees, branches, and power lines in Hampshire and Hampden Counties. Two people had to be rescued in Southwick, when gusty winds from the storms overturned their canoe.As the storms progressed into central Massachusetts, they downed trees in Worcester County from Hardwick to Northborough, one of which narrowly missed hitting a police cruiser. A nine-year old child was injured in Northborough by falling debris and there was structural damage to a building. Quarter sized hail fell in Webster, and quarter to dollar sized hail was reported in West Boylston.Wind damage was more severe in eastern Massachusetts. A National Weather Service Storm Survey concluded that a microburst occurred in Lowell with estimated wind speeds of 70 mph. Many pine trees were snapped near their tops to about one-third of the way down. A car was flattened by a fallen tree at a baseball field along Pawtucket Boulevard. Damage was also noted on Varnum Avenue, one block farther to the north.Elsewhere, there were many reports of trees falling on cars around greater Boston, including the western and southern suburbs. A wind gust to 60 mph was recorded at Blue Hill Observatory in Milton. Quarter sized hail fell in Stoughton and penny sized hail was reported in Salem.
