Thunderstorm winds damaged a home and took down some trees on Hawley Road on the west side of Montrose, near Route 706.  The thunderstorm then produced a significant micro-burst about a mile south-southeast of Montrose, impacting property along Peterson Road, Meshoppen Creek Road and Bolles Road.  Numerous trees were uprooted and snapped.  A tree damaged the roof and side of a house and another crushed a farm outbuilding.  Windows were blown out on a home, and damage was done to a silo and barn.  This damage occurred along Peterson Road.  The micro-burst then blew through farm fields and wooded areas, taking down numerous trees.  It crossed Meshoppen Road and Bolles Road, snapping additional trees on nearby properties and then appeared to weaken as it moved up a hillside.  The pattern of the trees that fell at each location surveyed was slightly divergent, which is indicative of a micro-burst.
