Today will be our 10th day in a row with highs in the 30s! Starting Christmas Day, our temperatures have not even reached 40. Our normal high for this time of year is 43, but we won't get close to that until next week. Perhaps this is our payback for an unusually warm 2012. In Louisville, it was the warmest year EVER since we've been keeping records back in the 1800s!
We had some excellent pictures posted to our WAVE3Weather facebook page of a parhelion during yesterday's sunset. While parhelion is the meteorological term, most just refer to it as a "Sun Dog". That's the common, much more groovy name... in my opinion.
A "sun dog" forms due to the refraction of sunlight by high clouds made of ice crystals... cirrus clouds. It is easiest to see a sun dog near sunset with the sun is low on the horizon. It often looks like two lights (sometimes showing the colors of the rainbow) on either side of the sun.
Here are some pictures showing the sun dog from last evening.
