————————————————————-
==weather event discussion==

The damage that occurred in a campground to the east of Amherstburg around 10:50 PM on Wednesday June 23 has been determined to have been caused by a microburst which is a very localized gust of damaging winds. The damage to the campground included a camper trailer flipped over and a large tent and small sheds being severely damaged. The damage occurred in a localized area approximately 60 metres wide by 600 metres long. Based on the type of damage that occurred the winds were estimated to be between 120 and 140 km/h which is the lower end of the Fujita one range. The Fujita scale uses damage to estimate the strength of winds in tornadoes and severe wind gusts and goes from zero (weakest) to five (strongest).

Environment Canada earlier confirmed that a Fujita scale 2 tornado (peak winds between 180 and 240 km/h) occurred in the Midland area around 6:30 PM Wednesday evening. The tornado began in the Rowntree beach area west of Midland and ended just west of Waubaushene for a total length of approximately 25 km. The maximum width of damage was around 300 metres. The most significant damage noted with this tornado was numerous mobile homes severely damaged or destroyed in a trailer park at the south end of the town of Midland. Damage outside of the Midland area was intermittent.

A second tornado spawned from the same thunderstorm that moved over the Midland area occurred at approximately 7:00 PM. This tornado began around the Maple Valley area approximately 10 km west of Washago and ended just east of Washago. This tornado was rated as a Fujita scale one tornado (peak winds between 120 and 170 km/h). The total length of the damage was approximately 12 km but was intermittent in nature. The maximum width was approximately 60 metres. The most significant damage from this tornado was to farm buildings (i.E. A barn and silo) and a garage.

With the confirmation of two tornadoes from Wednesday evening, the total count of tornadoes for this year so far in Ontario stands at four. Ontario normally gets around 11 tornadoes each season with the summer severe weather season beginning in late April and ending in early October.

EWR was unable to visualise the Midland storm as it was below the .5 degree tilt (lowest scan) of KBUF radar at that range, and KTYX radar was down.
