Thunderstorms possible 11-14 October, North Island

[spwill]

the cell just north of great barrier has suddenly come into life. If thats happening over the ocean it should happen over land should it not?

That storm will be on the front, heating would create a west coast sea breeze against the general NE flow and create local convergence.

[Manukau heads obs]

cloud cover increased here
so not much going to happen by the looks
looks instead like a day near Joplin waiting for the cloud cover to break...

[David]

Have just had our first glimpses of sun today, humid 19 degrees now. But there's no west coast sea breeze looking at your station Brian...

[Manukau heads obs]

yeah, no sea breeze, as too much cloud cover...

[jamie]

yup too much cloud here too. Stalled the heating and stuck between 20 and 21 degrees

[bmo]

Getting sun here now, no wind, 19.4C and really quiet...would. have loved some thunder

[Manukau heads obs]

looks like a couple of CB's have developed just on the west coast of northland

[Tornado Tim]

Somethings going on to my NW, might spark hopefully

[dan]

Out of the blue torrential rain here

[jamie]

yes came out of the blue that one. took some photos from my iphone and used a panorama app which looks great on iphone but crummy on computer.

[Manukau heads obs]

nice one

[NZstorm]

Yes, nice pics.

looks like rain coming into Auckland overnight but gradually clearing up tomorrow.

[Manukau heads obs]

that CB west of Kaipara I am picking up lightning strikes from

yes, the front looks to be re building west over the auckland area
cloud building...

[bmo]

Yes they are rebuilding over here, looking into the distance towards Dargaville the clouds look darker.

[Manukau heads obs]

and its raining here now

[CHCH Weather Chaser]

The rain band is becoming nice and established over the BOP now. The next 24 hours will be interesting!

[jamie]

Was just drifting off to sleep and heard a long distant rumble of thunder. Yippie.

[David]

The rain looks to be several hours away from here. Will be interesting to see how heavy it is.

[Manukau heads obs]

ground hog day here for us with another 13mm or so overnight
looks to have been a convergence/collision zone of different air masses combined with a lee trough, orographic lift on the coastal hills, from kaipara south

[NZstorm]

Looks like there could be some good heating over Northland today so Isolated thunderstorms may develop over western Northland, maybe western north Auckland also. Depends on how skies clear/amount of heating.

Tomorrow (Thursday) the cold upper trough starts to advance onto the North Island with afternoon thunderstorms/hail likely in central and eastern parts of the NI.

[jamie]

another 24mm for me. thats a good dollop of rain in the past two days. silage making rain thats for sure.

[NZstorm]

The colder upper trough moves onto the NI this afternoon and thunderstorms will actually develop today but they'll be over central and eastern areas and moving away in an upper level N flow.

Looking forward to some brighter weather in Auckland.

[Manukau heads obs]

heavy rain here now with a NW wind change here now...the front is finally moving over us now..

[Nev]

Slightly OT but, around the BoP I see MS recorded max-gusts of 135 km/h at White Island yesterday and 105 km/h at the Mamaku Radar. BoP main-centres also receiving around 70-100mm over the last couple of days.

[Vertigo]

some very nice rain being produced from a slow moving Cb above Auckland right now
