Active weather expected to materialize in the GTA on Thursday is shown on CP24's Future Cast radar. Environment Canada has issued a severe thunderstorm watch for Niagara Region as southern Ontario braces for another period of unsettled weather on Thursday afternoon. The weather agency says that conditions will be favourable for the development of severe thunderstorms across Niagara Region beginning this afternoon and lasting into this evening. It says that the storms could be capable of producing wind gusts of up to 90 kilometres per hour and hail that could measure up to three centimetres in diameter. There is also a risk of torrential downpours in the affected communities, Environment Canada says. There are not currently any weather alerts in effect for the GTHA itself. However, CP24 Meteorologist Bill Coulter says that Toronto could also see “substantial rain and thundershowers in the afternoon and evening” hours. “We’re not looking at the same intensity of storms as we saw earlier this week. There’s just less potential energy and dynamic forces at play. But, you’ll likely hear a few claps of thunder and flashes of lightning,” Coulter says. On Tuesday a major spring storm downed power lines and took down tree branches across Toronto. At the peak of the storm, Toronto Hydro said about 27,000 customers were without power.
