Wow, what a gustfront! Definitely the feature of the day. Unsurprising, considering the squall line that was on it's way from NE NSW at 4pm:
Healthy mammatus was already visible overhead in the northern suburbs of Brisbane.
Some smooth cloud edges also indicated something exciting was on it's way.
This was the final radar (5pm) before it went offline for about an hour:
I stopped at Springwood for my first view of the approaching storm and it's lovely gustfront.
At this point, it was time to go. Unfortunately, in my desire to keep snapping pics I'd left it too late to make it back to the highway to try and get back in front of the storm. We got caught and along with the heavy rain, there were plenty of branches over the road and the emergency stopping lane was almost full of cars pulled over. My main concern at this point, considering the incredible green colour, was hail. However, much to my surprise, we didn't get any.
The aftermath revealed lots of branches down, localised flooding and car accidents.
As the storm passed, it apparently hooked up with new storms NW to produce another line which continued on to the Sunshine Coast.
We then drove to Cleveland for the light show, however most of the bolts (ground strikes and anvil crawlers) were obscured by heavy rain.
