Simon wrote an excellent post yesterday on the snow. Etherial, magical, poetic, beautiful. I, unfortunately had to shovel my driveway, up hill, and so didn't find it quite so magical.
Do you write the weather when you write your stories? Is it raining, is it cold, is it humid and sunny? Is it important? Do you care if your MC's are cold, wet, hot, sweaty, hypothermic?
Do you find that you imitate the weather where you are? If it's nice outside, is your MC outside? If it's raining, is it raining where they are? Do you care if they don't have an umbrella in a hurricane?
