Great photo Richard.

Waikato convergence line looks great on radar, all the way down to Taranaki.

I went for an evening drive south into North Waikato and observed some thundery build ups down there, drove through some intense showers, a few photos below.

Great pics of some tropical showers!

The Waikato convergence line shows up well on this Weatherzone sat pic at 6-30pm also shows the SouthIsland Cb clouds near Richard.

Nice photo's guys! Could see the Cb's to the northwest from here in Christchurch although don't think the South Island ones did much apart from rain of course but have been busy today so haven't been able to monitor it. Look forward to more pics tomorrow should anything happen. Am liking that contrast Jamie in those Waikato photo's with the sunny foreground (that rainbow is nice to!), and the clear blue skies with a Cb in the middle spwill, quite photogenic.

Cheers
Aaron

Fantastic pics there spwill

love that middle one with wall of rain.
Hoping today's build ups are a lot close to the foot hills instead yesterdays one hiding away way back there in the mountains.

According to the World Wide Lightning Location Network site there was a strike or two out of the CB to the NW of us

Interesting to see Hamilton Aero picking up 30.6mm yesterday evening, while Jamie only got 7.6mm and Tim 0.4mm. Also looks like a few of those reminant showers made their way across SW Akld last night (10mm at Akld Aero before midnight), while the rest of Akld seems to have remained dry.

The GFS is starting to pull back on moisture/precip now for the NI so less of the heavy showers today. 500mb temps start warming a bit too after today.

I notice 850mb temperatures remain quite low for NI over the festive period, just 6C or 7C. As a very rough rule of thumb, you add 15C to the 850mb temp to get an idea of possible max temps. Over the South Island 850mb temps are higher 10-12C.

Just goes to how how hit and miss they are. Tim is pretty close to the airport yet he got basically nothing.

Hopefully today is just as good. Thanks for the comments guys. Have been two very picturesque days but I have been too lazy to get my dslr out to get good shots

Surprise rain in Oamaru this morning something left over from the showers over the ranges last night or a little trough developed last night and drifted east on to us . About 1.2 mm since 0600 now clearing to west

Yesterday the sea breeze front pushed a little too far to my west Hamilton Airport is 7 KS away to my SW just where the good showers were. Compare that to the 20th which developed storms quicker to my east and got more of a hit from them.

Yes no need watering the garden with the hose for a week running now.

I have been keeping an eye on a heavy shower that developed south of here a couple of hours ago, it looked like it was heading this way but has just passed to the west of here, heading NNW into central Auckland.

Manukau heads obs · Thu 22/12/2011 14:19

some build ups in Rotorua...but only looks like low level instability to me

NZstorm · Unread post by **NZstorm** » Thu 22/12/2011 14:30

Latest sounding indicates isolated cb possible with good heating.

Convergence line is further east today than yesterday.

Can see isolated showers to NW and E.

Dry here but with towering Cu overhead so we may see a shower, light winds 20C.

Very dark clouds to the south of here and getting closer, have not heard any thunder.

Tornado Tim · Unread post by **Tornado Tim** » Thu 22/12/2011 16:27

I wonder if those South Auckland cell(s) have broken the cap yet?

Anyone getting a good view to the south to see if there are any anvils yet?

NZWP 00Z sounding attached with the ML parcel trace shown in red.
