Abit of a cooler day today with the southerly, only had light drizzly rain overnight and roughly 3mm.
A few sporadical drops before though.
I would have thought there would be a greater risk for thunderstorms tomorrow than a ditsy low risk that the MS have up.
Call it wishful thinking but i reackon some good coastal thunderstorms will happen south of Christchurch tomorrow afternoon, slight gut feeling.

Just had a couple of very heavy showers come through, but nothing unremarkable.

Quite cool out, 12.4°C presently so I'm not expecting much to happen.

Unless there is a dramatic turn around in the numbers the risk looks very low Jason. Big problem for convection chances tomorrow is the upper air will not be unduly cold. Also the trough doesn't look very strong.

Not looking much over Auckland either.

The surface dp is as 13C but I think the real dp is more like 10C as the moisture is very shallow today.

Todays sounding from Whenuapai. Shows reasonably unstable air. But there is nothing like a front/convergence to focus the convection today.

Sadly Jase, I have to aggree with Steven W on this one :(
It's sad for us guys that we miss out on the action when other places around the country ie. western and northern NI can have a real 'feast' :yum:

I think it will be an interesting spring/early summer down there when the sea breezes start up, El Nino should keep the cold upper troughs coming .
We have had quite a few Tasman Sea lows this spring which bring good moisture down onto northern NZ, good for storms here.

Yes, looks like the trough is finally moving away from the country and a new system is moving towards us. :smile:

Check out that landcare research satellite image showing the boil up type thunderstorms on the s.i. west coast. I've not seen that before, except inland buller otherwise its rare indeed.

The thing with the South Islands West Coast storms are,they are normally associated with heavy overcast skies and are not always visible when approaching from the west.This is due to the steep assent of the main divide that backs up any of that on shore weather.
There are times where storms can be seen on the coast, but i'm talking about being on the beach damn near and getting as far from the mountains as possible,but for us Cantabs, its a long way to go just to sit in the car and wait in the torrential rain hoping for something, but only to get a very watery flash of light that you dont even know what direction it came from.

Thats not storm chasing as we know it

A series of cold fronts moving across us. One could, And I say could bring us some thunder related sounds on Thursday, this is depending of the lightning flash if such should occur.

Like the DSC in your avator John.

If you look closely, you can see me climbing up the steps into the cab of it. DSC 2718 in the Middleton Yard 1983.
