The best part is watching them arrive. Along the Gulf Coast, you can watch the thunderheads build during the late afternoon and see the cloud-to-cloud lightning light up cumulonimbus that rise to 50,000’ or 60,000’.
In the Midwest, they’re most impressive when rolling in with a fast-moving cold front. At night, the line of lightning will move from the western horizon to overhead – then disappear soundlessly into the east.
When I was in Congo-Zaire, our house sat 200’ above a plain that was empty for 10 miles to the south. When the rainy season arrived, the thunderstorms would appear behind the hills then roll across the plain before hitting the house. Then the sound of heavy rain against the corrugated roof was deafening.
In the summertime in the Midwest you can also see isolated cells. Once, flying from Chicago to Cincinnati there were isolated cells everywhere. Near Kokomo I encountered a chimney cloud that went from about 500’ above the ground to 30,000’. It was probably 5 miles in diameter and it would have been an easy matter to fly around it. And a dark, heavy rain was pouring out of the base of the cloud.
And what goes with thunderstorms? Hail, sometimes very damaging. Microbursts of wind that can carry the power of a tornado. Very damaging to aircraft, especially when pilots are trying to land just ahead of a storm. The smell of ozone after the lightning has passed.
And lightning strikes. One Easter in Chicago my daughter and I were sitting on the couch when the first storm of the season passed through. She was just 4 and just getting over the initial fear of thunder and lightning.
BOOM! “That lightning strike was near,” I explained. We didn’t know for about 30 minutes, but it had hit the neighbor’s house and knocked out everything electrical – the garage door opener, the heating/cooling controls, of course all of the TV’s and radios. A small finger of electricity had also hit our weather station, but only knocked out the windspeed indicator.
When you live on the West Coast, thunderstorms are rare and mild because there’s little heated ground between the ocean and you to create the tremendous convective activity. A friend from San Jose went back home to Chicago and found herself jumping with every bolt of lightning. She’d forgotten what it was like.
