EF1 tornado in Addison County, Vermont

The tornado developed over a wooded area west of Vermont Route 22A

and tracked northeast across 22A where multiple trees were snapped

or uprooted with numerous large tree limbs removed from trees. The

tornado tracked across a cemetery where a large tree fell on a

neighboring fence. From there, the tornado tracked across a property

where it uprooted a large softwood tree before entering a field and

throwing large tree limbs 50 feet. The tornado then tracked across

another property significantly damaging a metal structure and caused

it to collapse in on itself. The tornado proceeded to damage a structure

on King Hill Road before crossing VT Route 17 East where it forcibly

bent a street sign. The tornado continued into several fields where

many more trees were uprooted or snapped.

A unseasonably strong mid-level disturbance (shortwave) moved across a weakly unstable airmass during the evening of July 18th. Scattered showers and a temporary embedded thunderstorm or two developed behind the main rain shield and moved across VT. This particular cell had no history of thunder but enough of an updraft tapped the strong mid-level wind field above to produce a weak EF-1 tornado that lasted only a few minutes at most.
