The episode as NWS ALY wrote it up.
A warm front moved northward across southern Vermont during the morning hours on Tuesday, June 23rd. Behind this front, a warm and humid air mass moved into the region. As clouds gave way to partial sunshine, the atmosphere became unstable for the afternoon hours. As an advancing cold front moved towards the region from upstate New York, some scattered thunderstorms developed between the mid afternoon and early evening hours. One of these thunderstorms became severe, producing wind damage to trees.
As the cold front moved across the region, the threat for thunderstorms ended in the evening, as a cooler and less humid air mass moved into the area.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
