Sunday Story


Does Heat Lightning Exist? - ABC Columbia

July is the month with the most lightning strikes in the US. Each bolt contains enough electricity to power 56 average-sized homes for a whole day! 

Lightning is the product of one of Nature’s imbalances. The ice crystals in the top of a thundercloud are positively charged, while the liquid water droplets in the base of the cloud are negatively charged. When the two areas of charges become imbalanced, a lightning strike occurs to balance out the charges. 

Of most interest to us is the imbalance that occurs between the negative charges in the base of the cloud and the positive charges on the ground below. That imbalance of charges leads to cloud-to-ground lightning strikes. That’s the strikes that can prove deadly for us.

During the summer months, distant thunderheads can often be seen from the plateau. We are fortunate to have such a view! There have been times when I’ve spotted the lightning from thunderstorms as far away as South Carolina!

Many folks refer to that distant lightning as “heat lightning.” It’s called that because it’s most common during hot and humid nights. The lightning is not caused by heat. It’s simply lightning that is occuring in thunderstorms that are so far away that we can’t hear the thunder. Light travels much farther and faster than sound, making those distant lightning shows both beautiful and harmless. 

Storms that are close enough for you to hear thunder are not harmless. If you can hear that thunder, you are close enough to be struck by that deadly lightning. There have been documented lightning strikes that have traveled as far as 30 miles from their thunderstorm!  

Summer is a time of great outdoor fun, but we must always be mindful of any dark storm clouds that may gather nearby.

Drought Monitor

The drought monitor is updated each Thursday.
