The impression of the weather of Calgary

I have been here about 4 months. The weather here gave me the impression is big change. Why I said that. In Calgary, at noon the temperature is 5 degree, but at night it drops down fast to -10 degree. Oh, my god, I can't believe it.

I have encouter the coldest temperature in this winter, it was -48 degree. At that night, I went out to buy something from Safeway, on my way to Safeway, I felt the wind blowing to me like a knife cutting my hands. Painful!! However, few days later, the temperature rose to -15 degree. I think that's because chinook that is the warm air from the Pacific Ocean. Moreover, I remember that when my home-stay father drove me to look around the city, the heils suddenly fell down from the sky. At that time, I was so astonished why the weather suddenly changed.

Now, I am waiting for this summer of Calgary. I don't know what will happen in this summer, but big change is my impression of the weather in Calgary.
