There is some early TCU around north-west Auckland and what looks like a glaciated CB over the northern Kaipara area. Happy new years everyone.

yes, some great early morning CB's around
(I had to milk cows this morning)

No Cb' visible here, but what a nice morning!

Beats the 5C we had the other night!

Looks like it could be a good day for thunderstorms.. 500mb temps down to -24C today

There is a nice cell developing towards Auckland by the looks from local convergance.. diurnal cooling put a stop to all that convection over Eastland.. but strikes are gathering from there.

Will split this topic now..

Yes, lovely morn in Auckland.

Observed a nice thunderstorm in the Tokoroa area yesterday between about 6pm and 7-30pm. Nice CG's, some IC's streaking across the sky, very heavy rain and hail at times. I was on my way home and passing through Matamata about 5pm saw the convective development to the south and couldn't resist a closer look. The storm was worth the diversion.

I havn't looked at my photos yet but may put a few up shortly.

Heavy rain/hail over central AK at the moment!

It'll fire up nicely today I bet.. you gotta love these mysterious SE winds that run across the Waikato.

kaimaikid · Unread post by **kaimaikid** » Mon 01/01/2007 10:08

Very murky here with a current temp. of 15.3Â° and a dp. of 8.3Â°

fingers crossed that it will fire up again today

I see that there has been a actice cell or two already off the east cape this morning - the latest around 8ish...

The atmosphere remains unstable over much of the country today. However, there are some preventative factors at work over the North Island (such as cloud cover). There is still a low risk of thunderstorms about the northern Gisborne ranges, the Bay of Plenty, much of Waikato, the Coromandel Peninsula, and about the Hunua Ranges. Small hail, and localised heavy rain of 10-20mm per hour could occur with any thunderstorms.

In the South Island, there is a moderate risk of thunderstorms again today about the ranges of Nelson, with hail of 10-20mm diameter, and localised heavy falls of 10-25mm per hour. A lower risk of thunderstorms surrounds this area, and extends southwards to the Buller ranges.

No thunderstorms are expected elsewhere.

I could hear the roar of the hail from my veranda for several minutes before we had a drop of rain here.

Sunny here now with t/cu cb's to N/NE and SE.

Happy new year all... great skys to wake up to this morning!..
we missed all of the precipitation here this side of grey lynn but i think this was the culprit

spwill · Unread post by **spwill** » Mon 01/01/2007 10:49

We had a light white coating of hail through Mt Eden. Much of the Hail was pea size and smaller but the odd bigger stone up to 1.5cm as in Photo.

MetService talk about the inhibiting cloud cover.. but there's not that much around really.. just some altocumulus about.

Of course, when we chased 2 weeks ago it was all forecasted to strike around BoP/Coromandel but ended straight thru Waikato/eastern Auckland.

May go chasing today with Gary.. anyone else in?

Nice afternoon here in Grey Lynn, temp now 20C.

Can see a line of cbs to east and Rickys tracker has picked up some strikes in that direction.

Photo here of hail taken during last nights thunderstorm near Tokoroa. (stones up to 1cm)
