Today's Outlook Map
A very locally powerful storm yesterday over the city of Lethbridge, Alberta caused wide spread damage last evening. This was a situation that was not especially shown in the forecast models so just to be safe we are issuing a rather large area with a slight risk of severe thunderstorms. If things pan out like they did yesterday, there could be a lone cell over south eastern Saskatchewan that will becoming damaging with extremely high wind gusts. For most of the area, any storms will be general rain with some lightning.
In south east Manitoba and north west Ontario, a very different picture, with supercell thunderstorms wide spread with large hail, risk of devastating tornadoes and heavy rain moving towards the Great Lakes region. Luckily that area is very sparsely populated but there could be large swaths of downed trees as has happened in previous years.
