There is a chance, albeit slim, that the Aurora Borealis will be visible from the Pittsburgh area Thursday evening.
It only happens once every few years, and the past few times there is been cloud cover blocking the spectacle.
That will likely be the case again but patient sky gazers may see a greenish or pinkish glow through the clouds.
National Weather Service Meteorologist Jared Rackley tells KDKA Radio cloud cover will start to move in around midnight, so depending where you are, you may be able to catch a glimpse.
The Northern Lights can be seen so far south because of a huge solar storm sending a coronal mass ejection, or ball of plasma toward the earth.
In addition to cloud cover, light pollution closer to the city will make it difficult to see.
Rackley says the darker the sky and more north you are, the better chance you’ll have of seeing the natural phenomenon.
Even if get to see it, don’t expect it to look like it does in picture.
It will be faint on the northern horizon.
