A historical look at Prairie weather

Let’s look at the wildest, weirdest and/or most disastrous weather in Prairie history

Each year Environment Canada puts out its top 10 weather stories and I like to go through them taking a more western focus. While 2015’s top stories are not quite out yet, I thought it might be interesting to go back over the last 115 years or so and look at some of the biggest weather stories to hit the Canadian Prairies, according to Environment Canada. I’m not going to try and list them in any particular order; I’ll leave that up to you. I’m simply going to go in chronological order from oldest to newest.
