Temperature drop

Temperature has fallen drastically. If yesterday you could go out without any clothes and still wont get sick, today you would have to endure the bitter coldness. I thought it was just for the morning, but i was wrong! it stayed till night! well i guess the weather is unpredictable here. 1 day without sunlight might mean a temperature drop between 5-8 degrees, or maybe more. Guess i have to be ready next time.....
