Kuhryville, ON F1 Tornado of May 15, 2007

Huron - Perth

This tornado caused damage to a farm near Kuhryville at about 6:25 pm. There, a large barn had its roof and a wall torn off and thrown, with small pieces of debris being carried as far as a kilometre. A large pole barn was shifted off of its foundation and collapsed, and trees were snapped and uprooted. This was one of two tornadoes to strike Southern Ontario on this day; the other was an F1 near Winthrop.

Figure 1 depicts the surface observations at 2:00 pm EDT, which shows a cold front slicing through southern Ontario, where a moist and unstable atmosphere is present. This cold front initiated thunderstorms in the afternoon hours of May 15th, which ultimately led to two F1 tornadoes.
