Shows what looks like great tight cyclonic vorticity/rotation, that has been over the trail of areas reporting damage, at what must be a decent height at that distance from the radar, Interesting....

Theres a nice satellite shot, at the following location that shows the cloud structure circulating around a centre just to the W of Wanganui:

Wow! More tornadoes!

Nice flashes this evening to the west now.

Tokoroa - Lightening and thunder at a distance and squally showers as the last of the front passes over. Should be all clear by midnight. Baro stable at 998. Still 10.8ÂºC and wind around 20kms/hr.

Manukau heads obs · Fri 06/07/2007 06:50

always nice to wake up to a thunderstorm near by (over the waitaks )

looks like we are in for a big day aucklanders looking at what is heading our way in the tasman!!

TokWW · Unread post by **TokWW** » Fri 06/07/2007 06:53

Nice shot! I bet that made a bit of noise...yes - nicely angled camera- just perfect

A bit more thunder just this morning... and a gust to 50kms just before 6am...

Excellent pic!

Manukau heads obs · Fri 06/07/2007 07:18

yup, its looking tornadic today alright

TokWW · Unread post by **TokWW** » Fri 06/07/2007 08:36

Looks like some horizontal shearing stuff in there too. Gosh thats dark!! We had partial blue skies high cloud here this morning

Manukau heads obs · Fri 06/07/2007 09:20

i notice that the front last night had a big drop in the dew point behind it....so the cb lines are on dew point boundaries

new cb line developing nicely to my NW now

i think nzstorm and spwill might have gone down to taranaki to see the damage first hand, since they have not been on the forum so far today?

ricky · Unread post by **ricky** » Fri 06/07/2007 09:26

I see Metservice now have a risk of small tornados up for Northland today, certainly some interesting weather incoming!
I hope the guys are there getting some good pics.. I was very tempted to travel but could be too interesting up here

Thunder here at the moment

Manukau heads obs · Fri 06/07/2007 09:36

another flash and boom of thunder just now from the narrow cb line coming onto us now

I think NZstorm has gone down for some photo's.

Reports from last nights storms over Taranaki certainly suggest tornado's rather than just wind gusts.
Still a lot of weather action in the Tasman, lightning strikes over the last hr near Ak west coast.
A couple heavy showers here so far this morn.

Nice photo Foggy

Manukau heads obs · Fri 06/07/2007 11:07

this cloud base (wall cloud, showing classic leaning) has vorticity on the left hand edge...had a cyclinder shape ....and I could see that turning

(only a 5kms away from me

)
