Last week at home on the farm it stormed. The thunderstorm was sudden and intense, like most summer storms. They sweep in from nowhere. The sky stays blue and bright until just before it starts. The only warning is a subtle change in the atmosphere --- the air feels damp and crackles in anticipation as if with some secret electric charge. Clouds gather quickly. The temperature drops ten degrees. A few raindrops fall, becoming a constant patter, and then sheets of water sluice down from above. The rain is so heavy that your shirt soaks through when you dash outside to check your car windows.
