With only two weeks into the official start of spring, summer storms could begin moving across parts of southern Ontario on Wednesday.
While Environment Canada had not issued an official weather statement or warning as of Tuesday evening, Environment and Climate Change Canada (ECCC) Ontario said heavy rain, strong winds, lightning and hail were expected across parts of the region from the southwest to the Midwest Ontario. Parts of northeastern Ontario could also be affected by the storm.
Storm hazards may vary from city to city, although the system could bring wind gusts of up to 90 kilometers per hour and three-centimeter hailballs.
In addition to the thunderstorms, the Ontario ECCC said conditions near Windsor and Sarnia were also suitable for tornadoes.
Warmer-than-normal temperatures are expected Wednesday, with daytime highs expected to hover in the 20-23 C range for parts of southwestern Ontario. Areas around Lake Erie could be slightly cooler with highs in the 13-16 C range.
Unstable weather is expected to move out of the area on Thursday.
📢 Tomorrow’s storm could bring severe thunderstorms to parts of southern and northeastern Ontario!
