I saw that anvil to my NNE at 7pm, with a few bright flashes of lightning, though this cell carked it very quickly however.
Well we had out first taste of summer here yesterday and it came with a bang, just as much as when the southerlies kicked in. 39 was reached around lunchtime until this god awful NE wind bumped up the humidity and made things feel worse, though it did knock off the temp by several degrees the humidity was terrible, Brisbane reached 40 at 2pm and shortly after the change came through, us however waited until 5pm when this surge of gusty winds came through like a southerly buster and took away all the heat, it was refreshing to say the least, and shortly after this change moved through, thats when that Tewantin cell began to develop.
There was a lot of convection and low level cloud with the change, so it made viewing any storm development harder to see but by around 6:30 I was alerted to this very strong storm cell outputting massive amounts of lighting. I thought the lightning tracker was off it's brains because there wasn't much evidence of frequent lightning to my north though as I've said before I saw some bright flashes, it looked severe and on radar this proves it too, I was surprised nonetheless that anything developed considering the other circumstances.
