45mm today from convective heavy showers which became very loud and thundery..
The NZWP sounding had a strong cap at the tropopause height of 11km with some critical inversions.. CAPE today was around 430j/kg and LI down to -3. Not much wind aloft meant they could develop strongly too
Convection by all means isn't over.. with more outbreaks of thunderstorms developing the over next few days.
[/quote]Raglan area got 70mm from that afternoon storm yesterday, Te Awamutu got 58mm.[/quote]
Shower clouds were slow moving yesterday, I noticed that big Cb over west Waikato seemed to hang around there for several hours , no wonder Raglan got a lot of rain.
Heavy showers over AK yesterday afternoon were small so brief.
When the southerly change went through Picton yesterday afternoon there was a period of 20 minutes of hard driving rain, with a couple of claps of thunder. A little later, when conditions had settled back to just the odd shower, I was on the ferry in the sounds, and saw a small disturbance on the water (elsewhere in the area there was a fresh wind and small waves). It was no more than a couple of metres high and a few metres wide. It didn't appear to be rotating. It raced over the water surface, roughly with wind direction, and lasted about 20 seconds. Can vaguely recall seeing one of these before.

I don't look at that rubbish, i just look at the sky/weather predictions,scenarios and work it out from there

It's a bit different up here John..
You quote "weather predictions" or forecasts which is actually based on data from soundings which can give precipitable water, shear, helicity, total totals indicies, lifted index etc. Oh wait, that's all rubbish.
