After two consecutive days of tornado threats in Ontario, Environment Canada has confirmed the country's first twister of the year.

The EF-1 tornado occurred in the Midlmay area late Tuesday afternoon, packing winds up to 150 km/h along a damage path of 2 kilometres.

According to EC one house suffered significant damage. Barns, trees and power lines in the area were also affected.

The first tornado watch of the season was issued for the Windsor area on Monday followed by the first tornado warning for southern Grey County on Tuesday night.

The active weather was courtesy of a humid and unstable air mass that met with a pre-cold frontal trough, causing storms to develop.

"As those storms moved in over land across southern Ontario, they came into contact with the lake breeze boundaries that were in place," says Weather Network meteorologist Dayna Vettese. "As the storms interacted with those boundaries, the storms were able to spin briefly."

THUNDERSTORM RISK CONTINUES

Nocturnal thunderstorms will continue across parts of Ontario Wednesday night, including the GTA.

"The rain will persist into Thursday but conditions won't be that severe in the GTA," says Weather Network meteorologist Brett Soderholm.

"However, parts of eastern Ontario can expect significant storms on Thursday along with severe weather potential."
