Morden - Winkler - Altona - Emerson - Morris

Figure 1 shows the surface observations at 7:00 am CDT, which shows a cold front moving across southern Manitoba. We are unsure at this time how a storm could have developed from this setup. It is possible that a lake-breeze developed from Lake Manitoba behind the cold front, which combined with surface heating around Morden could have triggered thunderstorms.
