A nice line of Storms has developed east of Northland and is sliding SE, should be able to see lightning in Aucklands eastern sky when it gets dark.

looking dark from the east to the north at the moment, but with high cloud theres nothing spectacular to see. The lightning seems to be dieing off a bit now

Cant you remember 1998 was like that.

No, I wasn't a weather fanatic when I was 7!

massive lightning out west somewhere, about 5mins ago, took 30 secs for loud boom

Manukau heads obs · Mon 05/05/2008 19:10

heard thunder rumbing here from that...

jamie · Unread post by **jamie** » Mon 05/05/2008 19:14

i didnt hear anything but then we face the city so it may have been muffled a bit

Notice that the lightning detector didnt pick it up

Cameo1 · Unread post by **Cameo1** » Mon 05/05/2008 19:22

yes neither were picked up...strange

ricky · Unread post by **ricky** » Mon 05/05/2008 19:23

I was watching the detector screen at the time and it did but as very weak.. showing it about 500km out!

Manukau heads obs · Mon 05/05/2008 19:23

i have lowered my detectors electric fence supression to try and pick up more real strikes (but means I will get more false strikes (shows up as a blob to my east (sometimes as far east as tauranga)

Saw a couple of flashes out towards Henderson way. Am trying to watch for some more, but my little 2 year old boy is terrified.

They were actually about Matata, South Sou East of Tauranga, say 20km?

Good watching from my bosses at Oropi.

Looks like a low moved down to lie in the vicnity or northeast of Auckland, and I see the radar shows the rain band to have kept moving to the southeast with no significant wrap around on its western side. It was looking good for a while there! Oh well, we did get quite a good show of thunderstorms (mainly over northern Northland, out to the east of Auckland and down into the Bay of Plenty.

Vertigo; one idea that comes to mind are Landsat images (very detailed but only a couple of times a day being polar orbital - check out the Landcare (I think it is) site). You will have to search the Internet. Polar obiter images give highly detailed images. Come to think of it, I have a couple of links at work that may be of use. Will dig them out tomorrow for you.

That line has fired up nicely up the Western side of the Coromandel by the look of it

This is the Landcare link I've used for those sat images.. http://satellite.landcareresearch.co.nz/noaa/

cold here now this morning, 9.5oC
that is a huge cloud sheet just east of the kermadecs!

Paul Mallinson · Unread post by **Paul Mallinson** » Tue 06/05/2008 09:48

Yes it is massive. Thank goodness its going away for now! Some cloud top temps out there are -68C or so.

Vertigo, here is a link that might be useful
http://rapidfire.sci.gsfc.nasa.gov/realtime/2006047/
This is to the MODIS Rapid Response System. It gives you near real time images from two polar orbiter satellites called 'Terra' and 'Aqua' These orbit in opposite directions I think. Its a bit tricky to use - the tricky part interpreting when you get an image for the area you are interested in. But the images are very detailed.
