Just came across a website with lots of fun and interesting weather trivia; I thought I would share this:
Want a simple way to check the weather each day? Stare into your coffee cup (before you pour the milk). If you see bubbles floating toward the rim of the cup, it means that the pressure is low and you should look for clouds and stormy weather. If the bubbles float toward the center of the cup, it means that the pressure is high and you can expect fair weather. Keep in mind that bubbles will always float to the lowest point on the surface of coffee. So, with high pressure, the center of the coffee is pushed down and the surface of the drink is low in the center and high on the sides. When pressure is low, the center rises relative to the edge of the coffee.
