NWS in Mount Holly issued 123 thunderstorm warnings during July, the 2nd highest on record

The National Weather Service in Mount Holly, which serves most of the Delaware Valley, issued 123 severe thunderstorm warnings last month, just shy of the record set in 2021.

Meteorologist Alex Dodd said the storm spike could be attributed to the increased humidity due to warming waters in the Atlantic and Gulf of Mexico and fluctuations in the jet stream, which studies have shown are impacted by rising temperatures.

“That’s really combined to bring us a kind of a quick onset to a very wet and stormy late spring and the summer more than we typically see,” he explained.
