Yes the most amazing thunderstorm for the last hour here in kumara junction and still going strong, lightning every 2-3 seconds and window shaking thunder.

Large scale ascent upstream of the upper trough/jet has been fostering overnight thunderstorms over the South Island as expected. Interestingly a strong burst of elevated activity over inland Otago/Southland last night. I have seen that clip of the lightning at Alexandra!

Front over the west of the North Island has much warmer upper air. Looks like just heavy showers.

One of the best storms here for a long time

Found a long clip showing the frequency of the lightning near Alexandra here: https://www.youtube.com/watch?v=yngWmBIsgDw

what a great show

because it was elevated, is that why there was no warning on it from M/S?

Anyone grab a screen shot of the radar? Keen to see where this rain fell.

Manukau heads obs · Sun 29/03/2015 09:09

from what I saw, it was moving slowly SSE from the Mt Cook area, and wasa wrapping back down into southland even
so a large area of Central and Eastern Otago would have got rain..there is the last 8 hour rain radar on M/S web site...
farmers in eastern Otago needing dams filled should be happy

Couple of screen-shots of the Blitzortung tracker last night and this morn for those who missed it…

)…

Another clip, from Clyde this time - this isn't the one I saw on facebook but is better anyway: https://www.youtube.com/watch?v=3u2IsX_Vhy8

Quite a downpour in Alex last night…

The lapse rates over Canterbury are quite steep at 7C which is a good number for convection. GFS is plotting the afternoon convergence some distance inland.

I like the clip from Clyde.

More Thunderstorms rolling round the coast again.

today seems promising for thunderstorm activity around this afternoon in canterbury.
Im going to my sisters to watch the game but will take my camera gear with me

thunder here now

The Lightning frequency from those storms was quite high, signifies some very good upper level dynamics.
Some fairly high amplitude strikes around last night as well meaning convection was elevated.
