Take a look at what Lethbridge experienced last night. Up 16 degrees in one hour, then a few hours later down 18 degrees in one hour. That doesn't happen in a lot of places in the world.

My craziest Alberta weather story: I went to work the evening shift one night and it was -20 or so, when I came out of work at 1:30am it was +14 and my car had slid into to the middle of the parking lot, along with a few others while in park due to the melting??? I could figure it out.
Look at Crowsnest Pass today
