This was how the mid afternoon hail shower over Christchurch developed as it moved into Pegasus Bay later in the afternoon. About half an hour after these pictures were taken at Amberley Beach I got some small mushy hail and also some proper round hailstones as the land based part of the storm picked up some oomph.
Some nice photos there tony. I took a couple on my phone in chch to yesterday. Very photogenic!
500mb temp was a very cold -32 yesterday so very cold air aloft! A shame it wasn't a bit warmer at the surface to get some real storms going
The chase continues! I got between the two cells offshore of tangimoana beach at 10pm. There was constant lightning, several a minute but most were flashes so I don't think I recorded any forked lightning. Then upon coming back just north of the sh1 himatangi beach turn off there was piles of hail on the side of the road where the southern cell had passed through and some were the size of marbles. With more thunderstorms out to sea which could possibly not fall apart the chase continues.

I wish I was at Te Horo Beach today, where my brother-in-law has a bach there, to see these storms
Up there over QB WE but then there will a bloody boring anticyclone over us then
You can't win
At about 11:35pm I saw several forked lightning at himatangi beach as a thunderstorm approached then got pelted with hail as it passed over haha. Since then there's been lightning to north and east with some loud thunder

Wow wouldja look at that
wind 2.18pm 24-5-18.PNG
I see Cape Turnagain went on to record gusts of 220 km/h before 8pm last night, which I think beats its previous record of 213 km/h set just last month on April 10 (although no mention in NIWA's April summary) and its 209 km/h prior to that in Nov 2014. Also makes it the 10th 7th time Cape Turnagain has recorded gusts over 200 km/h during its somewhat checkered 9.5 year history.

If I wanted to look up some of that history on CliFlo, I wouldn't be able to - 1 week on, and they still haven't fixed a gross bug. Very unimpressive.

Yeah... sorry meant to reply to your 'CliFlo searches failing after server patch' thread earlier, so have just done so…
Another 20mm in the last 24 hours here. System 3 coming in nicely with cloud tops west of Auckland ahead of the front around -50c. Might start sparking again soon. Very unstable behind the front....interesting day ahead
EC, BoM, Ukmet and Canadians are jumping onboard with GFS and Icon for system 4 on Sunday. System 4 joining forces with system 3 in a fujiwhara effect east of NZ. Sharp upper polar trough snapping back north westward into upper eastern parts of SI and the lower half of the NI on Sunday night. A lovely southerly sting in the tail if it comes off.
Keeping an eye on system 5 next week. Upper cold pool is definitely getting over the Tasman with that high pressure ridge looking as weak as a wet raffle ticket. Still plenty of uncertainty though.
Very impressive hail, lightning and thunder activity here last night. I see some of the cells were given severe TS warnings on Metservice mid to late evening. I counted at least 4 close-range CGs, two of which must have touched down within a couple of hundred metres of here as the thunder was almost instantaneous and felt like an earthquake. Kids and dog not too impressed but I was pretty chuffed.
The "critical SW" flow is protecting us, not seeing much action other than out on the peninsula for us. Maybe a shower or two, Sunday looks best bet for even there I am not convinced if it being "southerly" enough down here
There were thunderstorms across parts of south and west Auckland before sunrise this morning.I took this photo of a thunderstorm cell over South Auckland.
