a comment on the weather

I had a lazy morning today and spent much of it reading in bed under the warm covers. Luckily I got up to check my email; otherwise, I'd never have noticed the snow falling outside my window. It was barely snow, just a fine mist with a hint of white, but I realized it must have been falling for quite some time. The handlebars and seats of the parked bicycles were caked, and the parked cars had a layer of frosting, too.
By the time I made my way out the door, it had all already melted, and the only evidence was the wet ground. Anybody who spent more time reading in bed than I did would never have known that it had snowed.
This is the second time I've seen snow in the month that I've been here. And they said it never snows in Shanghai.
It's supposed to be 64 degrees on Tuesday. These unpredictable, drastic changes remind me of Texas weather.
