Cumulus in the area are not even necessary: Blowing dust, snow, rain
and sometimes just wind can produce enough static charge to do this. I
had a 1/4 wave vertical on 40 that was direct fed with coax. When it'd
get windy the disconnected PL-259 would arc (Nice fat, bright blue one
that'd put an ignition system to shame accompanied by a fairly loud
*snap!*) at roughly 5 to 10 second intervals. Although often referred to
as precipitation static I can and does occur without precipitation.
Now all antennas are at DC Ground.
