Whenever you see a glaze come over the sky in the fall or early winter, it means one thing - cold and more moist air is moving in. You could tell it was like that because we had a lot of cirrus clouds and their cousin - cirrostratus. These clouds are made up of ice crystals as opposed to suspended water drops found in most other kinds of clouds. As the sunlight passes through these crystals, the light is bent or refracted. Its similar to what happens in a prism. Because the crystals are hexagonal-shaped plates, the refracted light always ends up 22 degrees from the sun and can usually seen on both sides of the sun.
Along with the sundogs, I also saw a lot of white lines stretched across the sky like this:
These are called contrails and they are basically the exhaust from jet planes that fly around 30,000 feet. Since the planes are always flying, you might wonder why we don't always see the contrails. The answer lies in what kind of air the planes are flying through. If the air is dry and cold (and it usually is at 30,000 feet), the exhaust, which comes out of the engines fairly hot may simply evaporate. From the ground, you might not see anything at all. The exhaust from the planes adds moisture to the air around it and it the air is already fairly moist, the exhaust condenses into a trail of water vapor or ice crystals. That makes a trail as the plane is flying and that's the white line we can see from the ground.
Either way, it is a sign of change because when the atmosphere becomes more moist in the fall and winter it can set the stage for rain or snow if a cold front or low pressure system is moving our way. As it turns out, the days after Tuesday have been mostly cloudy owing to the increase in moisture over Georgia.
Just goes to show that even if we didn't have all the fancy computers, we could expect certain kinds of weather changes by just looking up and observing.
