Winter Weather Proves Puzzling

What should I wear today? I seem to ponder this question every day. Thinking back, I can remember that it was rainy on Monday, rainy on Tuesday, sunny on Wednesday, and cold in the morning, bur warm in the afternoon on Thursday. The weather lately seems to change every time I walk outside. The temperature in the classrooms at school seems to change drastically also. So now, on Friday morning, I'm standing in front of my closet trying to decide whether to wear my long underwear or a shortsleeved shirt. I compromise, after minutes of standing there, and decide to wear my school shorts and a sweatshirt. The winter season is definitely setting in.
