Possible T-storms, Upper NI, 6th April, 2010

[Tornado Tim]

Hmmm At this point I am thinking its a "One Clap Wonder" setup.
The upper air looks a little stable for my liking.

But none the less a risk for Waikato, Tauranga, parts of Aucky/Northland.

You can see on the Skew-T that if any t-storms/showers develop they will have a lowish base to them.(They wont be high based storms)

[NZstorm]

With an upper trough/cold upper air in place over the upper North Island the thunderstorm risk for the Waikato/BOP looks fairly high this afternoon. Looks like there should be some low level convergence to trigger a few thunderstorms. I would say the chances for Auckland are low. Upper Northland should catch some activity.

[Manukau heads obs]

I think the low is going to roll over the top of the auckland area and the S to SE fow in behind will dry out quick over the NI land mass
so the auckland area i think will not see any more rain from this system
with a strong high and ridge coming in, its back to drought conditions!

Yes, need a good period of widespread rain rather than hit/miss showers

Some towering Cu in our skies this afternoon, a pleasant 22C Dp 16C.

Some thunderstorm activity over the central North Island currently

[Manukau heads obs]

can see some nice CB's going up in the waikato
SSW wind here now, so no chance of them coming up this way I would say

looks like the area just north of the bay of islands is getting a nice band of rain at the moment

MetService have a Watch for Waikato http://metservice.com/national/warnings ... torm-watch

[Manukau heads obs]

[ricky]

Nice to see active metservice warnings again

[Dale]

Very weak clap of thunder overhead Paerata/Pukke just now.. weak albeit thunder still.

[NZstorm]

Looked like a strong storm Otorohanga way. I was working on the Northshore and could see the cb tops from there. Static on the am band about every 5 seconds!

[Manukau heads obs]

that CB over your way looks good from here Dale with the sun on it...all white looking...but there is bits of cloud blocking the top from view

[Tornado Tim]

Looks like the otrohonga cell is going to pay a visit here

[ricky]

some local instability and showers over Auckland city caught on the webcam..

[NZstorm]

I notice some convection/glaciated tops just out to the NW of Auckland as well. Looked to have formed on the SE change.

[NZstorm]

I see Te Awamutu has had 42mm inside the last hr!

[ricky]

very heavy showers over the Hunuas too and some great looking clouds over Auckland this evening

[Manukau heads obs]

yes, NP rain radar is showing large areas of heavy rain down that way!
lucky them
there is a shower line out to my SSW moving my way....wonder if it will stay intact long enough....to get here

[NZstorm]

Hamilton airport reporting thunderstorm/hail.

[Tornado Tim]

Hamilton airport reporting thunderstorm/hail.

Hmm thats strange, that cell has died though (of any lightning activity)

[NZstorm]

It was a 6.30pm ob Tim. Today looks to have been the best set up for inland storms since the late January events.
Could be the last of the summer?

[David]

Had scattered heavy showers out this way. 8.6mm this evening, peak rate of 100mm/hr.

[Dale]

It looked good Brian but did absolutely nothing.. it was moreso over Bombay & the other side, Tim wasnt far off the mark, it wasnt a 1 clap wonder, rather 3 lol.. precip all around but not even enough here to wet the ground let alone anything else.'Noticed the glaciation up there too, looked pretty cool.

[spwill]

I went down to Bombay late day, Cbs produced a norrow strip of heavy rain across the top of the Bombays, plenty of water for some but yes dry for most.
