|Since it has not happened before in the time since we started keeping records, I thought it was noteworthy. I can't verify this, but someone told me it was the first dry Hallowe'en in Vancouver in 18 years.|
Although I have not lived in Alberta since I was 4, I have experienced snow in Calgary in all 12 months, so nothing surprises me about your weather.
One time I was playing in the Canadian Ultimate Championships in Calgary in early August. At halftime I looked around and noticed it was simultaneously sunny, raining, very windy, hailing, and sleeting, with thunder and lightning off in the distance -- lots of weather!
We are back to a normal November here now -- it is raining and windy. I'll take that over cols any day.
