Here on the continent they do a nice line in apocalyptic thunderstorms at this time of year. Sky's gone pretty much black, now the wind's picked up a lot and some fairly constant rumbling is approaching.
Question though - more often than not there's almost continuous lightening but hardly any thunder. Last night it was clearly overhead (or thereabouts) but only faint rumblings. Could the activity really be at very high altitude? I mean I know there are high altitude phenomena but I always thought that was just an extension of the low down stuff.
