The "Dog Days" of Summer

A Heat Advisory continues for Thursday. However, there will be an increase in shower and thunderstorm chances during the afternoon to help provide some relief. This should continue into the upcoming weekend with even higher rain chances by then.

So, we've heard of the "Dog Days of Summer" right? Here's a bit of history of where this came from. The dog days date back to the ancient Greeks and Romans. They would keep track of the seasons by looking at stars. The star Sirius was known as the "dog star" because it made up the nose of a constellation shaped like a dog.
