Meteorologists must spend all their down time inventing terms for the next big climate moment. “Polar Vortex”, “Snowmageddon”, “El Diablo”, and now “Heat Dome”, are some of the more recent ones. I say this in admiration, as we all feel better when the weather changes and we know we’ve survived whatever-it-was.

In the Midwest, and much of the country (I believe), it was heat combined with high humidity that made Thursday through Saturday of the past week unbearable. Whether you got up at 6 am, or stayed up until 11 pm, it always felt hot. The humidity made the atmosphere feel like a steam room, or breathing through a hot face cloth. There was no reason to go outdoors at all, unless it was to hurry to an air-conditioned car for a drive to a swimming pool or an air-conditioned building. Those days felt exceedingly loooonnnnnngggg, because there wasn’t a reason to do anything or go anywhere.

Rain poured down in heavy showers across our area late in the day on Saturday, and the heat began to abate. By Sunday morning, it was just another glorious day of summer, with the Heat Dome safely in the past. I wonder what they’ll call the next heat wave? It’s not even August yet.
