Unstable low over North Island Thurs 4th to Sat 6th

[Nev]

Isolated storms near Ak west coast and the outer Gulf in the early hrs.

Yes, quite a spectacle from here apparently. That burst of heavy rain, wind, thunder and lightning seems to have woken everyone else up except me... (mind you, I had spent yesterday helping shift house).

Sunny here now, but sort of hazy out in the Gulf..

The Cb line coming down over Northland is something to watch.
Variable cloud cover here, some small towering Cu around, 18C dewpoint 14C.

Partly cloudy here, 19C with a 16C dewpoint. Plenty of warmth and moisture to fuel storms
Went for a walk around midday and it felt quite muggy.

[spwill]

Quite an active looking Cb line about to move into the kaipara area

[Manukau heads obs]

YES, I like the look of the CB line moving towards us from the NW

[Storm Struck]

Some very sharp readings on the radars coming up for Auckland, could be some decent sized hail stones in there maybe up to 20mm.

[bmo]

Some distant thunder heard few minutes ago, big rain drops falling right now.

[spwill]

Shower line forming along our west coast now

[jamie]

Development right over your place brian.

[NZstorm]

Midday sounding taken at Whenuapai. Over 500 CAPE.

[NZstorm]

Gone for drive out to NW Auckland and lightning thunder observed.

[spwill]

Thunder heard here in Mt Eden from the shower line through the west

[C-Nimbus]

Thunder and moderate rain here in Henderson. Radar looks like this is just the start. Plenty of purple blobs!

Such a stark contrast to where i have spent most of this week, which is Alexandra. Every day was the same, i.e cold frosty mornings and then into 14-16degC highs during the day. Those temps felt like a 20degC day in Auckland. One assumes this is due to the lack of humidity in the airmass down that part of the country.

Anyway, hoping for a Friday night lightning show.....its been a while.

Hope everyone is well

[Vertigo]

I see a rotating signiture in the rain radar in the past hour, west of Northland. Looks too tight to be a low center, possible funnel?

[Manukau heads obs]

was a really good thunderstorm here at 2:30
developed very quickly
we actually had a bit of a sea breeze developing down the coast line and so I think that was the trigger

[Manukau heads obs]

looks like Raglan next in the firing line

[spwill]

Good to have your weather report from Henderson C-Nimbus.
A NE breeze here during unstable weather quite often seems to result in an afternoon Cb line forming in the west
Some showery rain has arrived here, earlier thunder rumbles out of the west.

Nothing of interest here, 1mm of patchy rain since 4pm

[jamie]

between 4.15 and 4.30 there was an interesting hook on the radar off the west coast of auckland between kaipara and manukau harbours.

thunderstorm at raglan ATM

[NZstorm]

Interesting to see the very heavy rain at Albany and NW Auckland didn't make central Auckland. Only 3mm in Grey Lynn

[Tornado Tim]

Some Good Thunder in Raglan
Line coming in from the west.

[Manukau heads obs]

we had like 6mm in like 5 minutes here at the peak of the system at 3pm
(4.79mm/min rain rate, which is real decent)

the current rain system over us is feature less looking cloud ...could be an occluded front
there is now a NW wind change here, so that will be the reason for the rotation on the rain radar

[treetop]

nothing here in TGA just drizzly gloom.Some heavy showers coming in now,active looking rain band over coromandel preasently,heading this way.Picking it will get a boost of moisure and intensify further with some rumbles as it moves east.

[Nev]

MS have just a moderate risk this arvo from about north of the Bombay's…

Valid to: Midnight Saturday 6 Sep 2014
Issued at: 7:46am Saturday 6 Sep 2014

A low pressure system is moving slowly eastwards across northern New Zealand today. A rainband over the eastern Bay of Plenty and northern Gisborne, with a low risk of a few thunderstorms, is expected to move away to the north this morning. Scattered heavy showers are likely for Coromandel Peninsula, Auckland and Northland throughout the day, with a low risk of a few thunderstorms. However, afternoon heating and convergences increase the risk of thunderstorms to moderate over these areas, which may produce localised rainfall rates of 10 to 25mm/hr and small hail.

Going to need good heating to get lightning today. Otherwise just showers.

Yesterdays weather was thundery rain rather than thunderstorms. Nothing photogenic and nothing too electricaly active.

Grey Lynn is on 85mm for the month already!
