Heat fuels severe thunderstorm risk in northern Ontario

As temperatures heat up across Ontario, Northwestern Ontario is going to be looking at the battle of the air masses heading in to Monday night into Tuesday. A warm front pushes into the region and then the cold front on the back end of it is going to be cutting right through that moist warm air to bring the risk for some non severe as well as some severe thunderstorms. Now across regions of Fort France through Armstrong, that's where we can be looking at the risk for some more severe storms bringing about them with them rather large hail, strong winds and heavy rainfall. But there's also a risk of some super cells and rotating storms just West of Thunder Bay. Now let's time the system out together. As we're heading through into Tuesday morning, the initial band of the warm front pushes in, bringing with it heavy rainfall for areas across Kenora, Dryden and Red Lake. As this pushes further towards the north, we can still expect some thunderstorms with it, but the cold front on the back and that's what's going to really lift these storms up, bringing about the risk for those severe thunderstorms as well as some rotating storms into the evening. Now in terms of the actual rain amounts within thunderstorms, we can expect heavy rain. So those rainfall amounts can be anywhere between 30 all the way upwards of 50mm.
