No surprise there Brian - we have a low thunderstorm risk on our charts...

It was a sight to get out of bed to Brian thats for sure, had an unreal sunlit view as they came over, black as night.. we must have been in a gap between them as you could see it was torrential up towards Drury & back down over Pukekohe but just some light rain here. Lots and lots of low scuddy stuff spinning around & up into the base, almost trying to form some sort of funnel as it passed over me towards the motorway.. havent been that upclose & personal with spinning scud in a long long long time (ie back in aussie)

What a way to start the week

We have just had a heavy shower here with small hail.

I woke up just before 8 and saw an angry looking dark cloud coming towards here....with a little bit of ragged white cloud under the dark base....hoped for hail or similar but it was just rain...

Just heard a roll of thunder somewhere in the distance!

the MS thunder outlook has nothing for up here...

Daytime heating is helping produce heavy showers this morning, Cb in photo developed over land from small Cu.

CHCH Weather Chaser · Mon 23/08/2010 12:08

Some CU clouds above the low cloud can be seen now in some of the clearing patches.

Yes DTSH is starting to have an effect now, since we are coming out of winter

May the storm season come with a big bang

Neat photo spwill

CHCH Weather Chaser - no low cloud here so i'm able to see a lot more of these CB's which are popping up all round ,some are starting to get up quite tall like this one to the west.

Looks like a weakly unstable airmass spanning the whole country today. Lapse rates over most of the country are 8C, fairly steep with LI's around zero. A lack of heating will keep any convection fairly weak.

Fairly dark skies near Kaiapoi at the moment, swirling and towering CU bases just waiting for a famous funnel cloud to drop down

.
Cloud heights look reasonable too, and there's been plenty of sunshine earlier too after the fog this morning.
Maybe a heavy shower soon with some tiny hail.

CHCH Weather Chaser · Mon 23/08/2010 14:07

Thunder here also to my NW,three good rumbles so far $\:D/$

Storm Struck · Unread post by **Storm Struck** » Mon 23/08/2010 14:12

Just did a wee bit of filming had more thunder and two lighting flashes, seems to be a converged line pushing into the SE wind.
Back to a lighter rain now and thunder rumbling more inland of Woodend now.

Just thought we could make a new topic so we remember the date rather than just being in general weather.
Thundery showers across several parts of the country today and more to come in many areas.
Moderaters could move previous posts even from your activity in the NI to here.

Storm Struck · Unread post by **Storm Struck** » Mon 23/08/2010 14:46

Skies seem to be stabling out abit now more glaciated looking, and just light spotty rain at the moment.
2.7mm since 2pm.

Getting a good hail shower coming through here now. Some good cu cloud forms around this afternoon as well.

NZ Thunderstorm Soc · Mon 23/08/2010 15:53

Something thundery looking going up in "Thunderstorm Corner" at the moment.

Looks a great cb blow up over the southern Waiarapa. Check out how quickly that anvil developed on weatherzone satellite.

This is a good one shows the scatterd CB showers over the top half of the South Island plus that developing CB over the lower NI.
