"Yellow warning of thunderstorms" (at last!)

Yesterday was the last day of a long heatwave, one of many we've had this year. Too many in fact. But now the temperatures have dropped significantly, it has rained regularly all day (not heavy rains, but still) and the BBC even gave a "Yellow warning of thunderstorms" for the area. We haven't had one yet, but I welcome it. I love storms, for one, and it is such a welcome change after the heated inferno of the last week. So bring on the storm.
