A Severe Thunderstorm moved across Lake Champlain at approximately 615 pm on Thursday and moved ashore on Potash Bay Road in the town of Addison, Vermont. The NWS Burlington office conducted a storm survey earlier this afternoon and has preliminary assessed that the damage was a result of a Microburst with estimated wind speeds of 80 to 100 mph. It appears the microburst initated over Lake Champlain and then climbed the 50 foot embankment from the lake to the lakeshore on Potash Bay road. There was substantial tree damage of softwood trees such as willow and pine trees that were snapped and uprooted along with broken branches on Potash Bay and Lake Roads. One residence at 296 Potash Bay Road was destroyed as it appears the roof partially lifted off from the structure, as a result of a very strong west wind that was lifted from tha lakeshore to the residence, and then the winds caused the structure to collapse upon itself with one occupant inside that suffered minor injuries. There was sporadic soft wood tree damage within a few miles of the above locations, including Route 22A. Also, there was substantial hail damage to siding of several residences on Potash Bay Road. Based on size of the holes on siding and eye witness accounts, it was likely hail size was 1 to 1.5 inch in diameter accelerated by 80 mph winds. Remember, severe thunderstorm can do as much damage as an EF-0 or EF-1 tornado and generally have a larger areal extent.
