Something else that was impressive about this storm was the temperatures. A very strong CAD that caused temperature drops of 30-35 degrees in a matter of 12 hours or so before precip began. During the storm, temperatures hovered between 25-28 in my location for the entire storm. So much for latent heatingI just now realized that today is the 20th anniversary of one the worst ice storms ever to hit the Carolinas. Everyone that went through that will always remember the sounds of trees snapping and power transformers popping. I was living in Concord, NC at the time and after a really quick 1/2” of sleet/snow, precip changed to light freezing rain and and it continued steady for 18 hours. Biggest ice accrual I’ve personally witnessed just a bit over an inch thick.
