Nice bonus to look up and see a funnel ! The lightning show you observed is great too - there's been a few offshore thunderstorms past few weeks and wondered if you'd been out and about. Work is a menace eh
Been some storms along the NSW/QLD border ranges and more-so into SEQ Fri (22nd) and Sat (23rd) with some flash flooding in the Toowoomba area Saturday night. Rainfall amounts recorded appear to be around 50mm in 30 minutes, though the 24 hour radar accumulation suggests falls in excess of 100mm.
Friday night (22nd April) I took some shots of an isolated storm which was about 100ks NW of here
