Why Can't the Weather Just Adhere to the Norms?

Yeah, I hear you. I live in Alberta, and we've been having crazy weather this winter. We haven't had this much snow here in almost 30 years. Then after this bad snow storm in early January, we had this awful cold snap where the daily HIGHS were in the -20s (Celsius), some days with wind chills in the -30s for an entire week. It was brutal. In the last few weeks, we've been having extreme temperature swings. For example, two weeks ago we had one day where it was 10 degrees C, then a couple days later it was minus 30. I'm in Calgary, so we get chinooks that bring warm air over the Rockies, and can cause really sudden temperature increases, but this year has been bad even for Calgary. We have a saying that you can experience all four seasons in one day here. And there's really no such things as "spring" or "fall" either. We had snow at the end of may last year--I was digging my car out from underneath 3 foot drifts. I guess it just to the point where you no longer have any expectations of normality at all...
