Early this morning, it was pleasantly cool at the cottage, prompting us to take a walk around Sandy Lake, on which it sits. Within a few hours of our return, a strong wind had developed, dragging warm, humid air up from the south.
Checking the National radar, the culprit was obvious. A potent cold front, then producing thunderstorms in the Chicago area, was pressing eastward, about to cross the Great Lakes. A tornado watch was issued for southern Michigan and northern Ohio; at the very least, we expect strong thunderstorms by late this evening, fueled by the sultry air that is now streaming into our region.
Well before the advent of modern meteorology, humans certainly knew that strong, warm winds often precede thunderstorms. And exposed to potential injury, they were surely more inclined to heed nature's warning than most of us are today.
