Stormy weather

We were sitting outside listening to the rumbles of thunder and watching the dark clouds and Gordon was explaining about how thunder occurs, as he would. He has probably done this many, many times and I still don't understand (more to do with not being particularly interested than anything else). Anyway the word convection was uttered, just as we felt a sudden wind rush through the garden and we hastened inside. However, and much to Gordon's disappointment, the storm passed over us. It did rain a few minutes later, but no dramatic storm. Then the sun came out, a blue sky emerged, white fluffy clouds, and it is now a lovely evening. Weather. . . !
