[Manukau heads obs]

we had fog as well..shows there is lots of moisture about!

looking like scatered rain tomorrow....

[spwill]

We get our first taste of Summer like humidity here tomorrow with 18C dewpoints but it wll be under cloudy skies.

GFS not looking as cold in the upper levels as few days ago, downgrade thunder chances with this system, some cold upper air tracks across NZ Friday but surface conditions may spoil

[David]

Hmm still no rain here. Warm overnight with 17C and 97% humidity

[David]

Metservice has a moderate thunder risk here for this afternoon/evening. A very overcast day; not sure if we will get near the forecast high of 23

[Manukau heads obs]

NW change here now

It's making sleeping difficult for me. Heaven knows how I'd manage any sleep in somewhere like Darwin without Air Conditioning.

Lots of people here are pleased to see a little rain, it's been very dry with little rain in November.

looks like a nice active CB line will move onto the upper NI late morning...?

Just had an odd occurance in Takapuna.. its been mostly cloudy with not much to speak about, good visibility generally, the odd spotty light rain.. then suddenly while I was working just now, a fog bank rolled in from the sea, accompanied by strong winds and higher air temperature. Have a video uploading, you can see the fog blowing past buildings.

I have seen the sea fogs roll in on the North Shore in the past, they can look impressive. Its an unsual case of warm advective fog.

Thunderstorm approaching the Kaipara area. currently 22C, dewpoint 20C, sun trying to come out now.

Looking from Auckland airport westward - talk about BLACK!!! Radar showing some good activity. Inbound flights off the Tasman taking some detouring around the cells.

Back in the late 80's when I was working in Takapuna, we had one that lasted until about 3pm. You could see it drifting up and down the street like smoke. Every time it looked like clearing, a new lot would roll in. It was about 23 degrees at the time and the whole place smelled like seaweed.

Edited to add: Just heard a long rumble of thunder here in Glenfield.

[Manukau heads obs]

amazing thunderstorm here
3 to 4 seconds from big bright blue flashes to bang/boom thunder!

very little wind here, in fact its gone SE even..
heavy bursts of rain too

[NZstorm]

Been hearing plenty of thunder here in Grey Lynn but its all distant west.

Someone on Newstalk ZB at the moment saying a tornado just went through Hobsonville Point. Big light tower taken down. Not sure if it was actually straight line winds, but damage certainly done.
