If you're used to sun all the time, cloudy weather and more indoor-time due to rain can throw you off. Might be a mild version of seasonal affective disorder -- the depression that strikes some people in far northern climes when the days get real short and cold, and they don't get as much natural sunshine. Some bodily processes do work best with a lot of sunlight, and it's possible that a drop in the amount that you're getting could affect your mood.

Where my mom lives, it's essentially gloomy and unpleasant from November through early March, and her mood goes right through the floor. I got her one of those "daylight" lamps that put out the same spectrum of light as natural sunlight, and she said it helps her.

Changes in air pressure and humidity, as when a new storm system moves into the area, can sometimes throw you "off" a little, too. This is my personal observation. But it seems to me that on days when the weather is changing rapidly, in an extreme way, people's behavior is also a little extreme -- a little more emotional, a little less patient.
