Some good convergence in the west today from Northland down to central NI. Quite moist air over Auckland today with the dewpoint up to 14C.

Judging by the t/cu around here today, not surprised some ended up thundery inland.

TT chart for Thursday, area 50+ for inland North Island and upper South Island. Could be a good inland storm day, if the gfs is correct.

Like that first photo Jamie

Cloudy here this morning,wondering if its going to burn off??

I thought it would be good to make a new topic for this and if one of the MODS could drag over yesterdays thunder posts to here.

It looks like we have a couple of days of thunder in a row for large parts of NZ with this high pressure system.

MS has "no thunder expected" for Waikato yesterday. They did mention showers but they didnt expect them to turn thundery. In the end they were quite good storms.

Today in their outlook they have upped their game and put out a moderate risk for Waikato so game on again today.

Looking at the models tomorrow should be even better.

It was interesting to see those late storms over Waikato last evening. I will likely go for a drive south later in the day if some decent convergence starts to show up on radar.
There have been towering Cu showers visible to the SW of Auckland this morning , radar shows them off the coast at Raglan.

Current weather here is mostly fine, 20C, dp14C, light winds, a few cumulus clouds around.

jamie · Unread post by **jamie** » Wed 21/12/2011 17:17

looking like it was yesterday at the same time. showers to my SW and hopefully something develops to my E again

Can see some shower clouds in Southwest Auckland area now. Perfect sunny day here today.

Some heavy showers developed over South Auckland near the West Coat after 4pm, sea breeze convergence ( photo). I went for a drive along the Southern Motarway, showers look weaker now.

Tornado Tim · Unread post by **Tornado Tim** » Wed 21/12/2011 17:29

Seabreeze front just came over with the convergence line right over head

Id wait a bit longer spwill, it seems around 6-7 PM that these showers get some kick.

Great picture spwill! Some pretty intense showers showing down in western Waikato.
5.05pm radar, for reference:

jamie · Unread post by **jamie** » Wed 21/12/2011 17:53

Richard · Unread post by **Richard** » Wed 21/12/2011 17:54

The temps have really heated up here today in land so some gorgeous looking builds ups near the main divide,its only been since about 5.00pm that they have started to bubble up
