Very loud here, looks like it's coming this way

Looking towards Auckland City from Takapuna, looks really dark and menacing. My colleague just witnessed lightning. I just received a pre-production sample of a Blunt umbrella I'm thinking of ordering for my company - looks like I'm about to get a really good opportunity to test it out.

Lots of thunder to east.

Seen a few CGs, last one made a massive splitting cracked sound. Raining now

Real nice thunderstorm, that one. Was standing within a few hundred meters of the Skytower, but didnt see any hits, boo!

Fantastic sounding thunder from almost overhead here in grey lynn.. long with lots of crackles in the sound

Yep best thunderstorm here in a while! Lots of lightning and thunder. Still rumbling in the distance now. Here is a pic I took of the rain-free part before it hit (didn't have a good view of the rainy part)

Good lot of Thunder in Matangi too Although the storms look rather featureless if your underneath them...

Took a little clip on my phone during the heaviest part. Didn't capture any thunder or lightning though sadly! https://plus.google.com/106853716585182 ... GkT2rhf3C4

the CB tops looked great from here from that Auckland city cell

CB's giving rain in an area that has been missing alot of rain lately...Maramurua and Hauraki plains ares
farmers will be happy in those areas

You tube clip of the waterspouts in BOP last night. These were the classic text book, non mesocyclonic waterspouts.

cool seeing the clouds moving/rotation in the funnel, via the zoom (good zoom on that camera)

Headed over to eastern Waikato mid afternoon, observed scattered heavy showers and the odd thunderstorm.
A few photos

These CB cells seem to be more fruitful that the useless cells off TC, the other day.
Why do Auckland and up there get the lions' share of TC development and not here

massive thunder and lightening here in the western bays over last two hours, dark clouds look like they are going to drop rain again soon from pureroa forest park direction, massive swirling...

The storms I observed in eastern Waikato had plenty of thunder, intense rain but a poor lightning show

Auckland has had a stable summer, this being our first storm since December. I think the whole of NZ including the West Coast has been below par for activity.

Nice captures spwill.

Akld City's T-stroms yesterday arvo kinda broke up before they made it here. Looked good though.


Bit more info on Thursday evening's spouts…

Drove through showers (not heavy, but big drops) bringing in a Mobile Dental Unit late yesterday afternoon. Apparently lots of thunder, but I didn't hear any and saw no lightning. Certainly some impressive looking towers and dark clouds as you went under them.

Have to say those NIWA climate maps are a complete joke, they show between 20-50mm this month for my area north of the waimak, a soil moisture anomaly of normal and drought code of normal.
There has been little rain of note and nothing has changed from 6 weeks ago, its still dead brown and dusty and the Ashely river is coming into its 3rd month of being bone dry when the Niwa maps show a rainfall anomaly of 140-160% in the head waters of that river.
I think Chch aero is around 11mm so hardly normal.

Readings from my station:

Ave temp 16.7°C
Ave Minimum 11.4°C
Ave Maximum 23.9°C
Minimum 4.8°C on 5th
Maximum 30.3°C on 2nd
Rainfall 16.4mm

Another dry month which makes summer 14-15 the lowest of any 3 month "season" (from autumn 2002) that I've recorded with 54.8mm and almost half of that was December. The next driest season with 71.4mm was spring 2014 so that makes only 126.2mm in the last 6 months... The average for spring + summer is about 250mm.

Summary from my station:

Avg temp ........ 19.8ºC
Avg minimum ... 15.6ºC
Avg maximum ... 24.9ºC
Lowest temp ..... 12.6ºC
Highest temp .... 27.8ºC
Total rainfall ..... 40.8 mm
Yearly rainfall .... 53.0 mm
