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.

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 second tornado has been confirmed by public video northeast of where|the Addison tornado occurred at 6:50 PM EDT. Video shows damage to|softwood trees. Locations are estimated from video and radar.

4 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
