I thought when a NW wind came up about 11.00 that would be it for here but the last half hour i think it will hit here now,very dark to the south with distant rumbles

I saw ~6 bits of IC lightning with occasional Thunder here in Hornby. It also had a bit of heavy rain. Does anyone know why the best bits of storms like to skirt the city?

The best lightning also had the worst conditions with the arrival of the gust front (recorded 62km/h) and torrential rain/hail briefly reaching 100mm/h ! Rain and hail slush was pouring over the gutters.

It was a very defined wall-cloud, wasn't it.

I'm still hoping to hear where the 2 to 2.5cm hail was photographed and observed?

Report of 1.5cm hail at Westerfield.

Well done Jason. Went for high risk and mentioned the jet stream and onshore winds. Good convective forecasting!

Nice gust front pics.

Yes, well done.
The hail here was probably marginal for denting cars, nevertheless it was the biggest I've ever seen and I was glad the car was under cover.

A stitched panoramic view I shot just after crossing the Rakaia back towards Christchurch. I wanted to get around the edge of the front to the left by driving towards Southbridge, avoid the rain and hopefully shot some lightning from behind the front but the whole damn thing was wider than I thought ...

Yes, the old gusto front does look dramatic, and the associated wind change and the heavy rain accompanying it, with the added lightning features like today.
Even I closely watched , there was no tornado effect, as the cloud rolled over, despite the active lightning within the cloud, in behind.
