That cold pool shows up well on sat pic this morn. Just getting onto Fiordland now. Clearance of high cloud moving across the SI which should allow for afternoon heating Canterbury. We should perhaps start a new thread on this next round of instability. And i'm picking the chance of thunder in Auckland on Saturday.
Taking up NZstorm's idea of a new topic here.
Yea that cold air is rather visible isnt it. Does that mean is super cold??
I like the looks of Auckland and western Waikato on saturday
Well I've spent all day in the McKenzie basin and south Canty in rain. Very heavy on the drive back this evening from Geraldine as far as Rakaia, with lightning and thunder. Looks like its about to arrive in ChCh shortly....
well i can say we havent got any storms today but sure did look unstable as that S was coming in, so abit of instability
Good to see some rather unstable air and more changes coming in!
Nothing in central Chch so far (and still doesn't look too threatening, though it's cloudy), but according to radar there's been precipitation in at least northern Chch in recent hours.
14.2mm at Tara Hills between 6&7pm.

Yes it is Jaime.. i'm not sure what world Micheal is on, but -25C @ 500mb there over Westland for mid-February is pretty cold.
Should finally see a windy day today! Westerly expected here with gusts to over 60km/h likely.
16mm of rain since midnight plus the 2mm we had at 7pm last night and still falling at 10mm an hour so going to be a very wet month here with around 100mm so far.
Yup, they are dancing in the paddocks round the province now, fantastic stuff!
Now Aucklanders- you are allowed some rain today, but not between the hours of 2pm and 10pm approx, depending on which England team shows up at Eden Park!
Its nice to be comforted by proper southerly rain after the heat of summer that we have had and Saturday is coming. With the next High emerging, - will that rise up through the Tasman and give us calm hot weather or will it stay low and more Nor-easterlies predominate the NI?
Met-Vu shows the High settling over centre of NZ on Monday but shortly after another tropical cyclone visits us on Thursday - Friday with strong Nor-easterlies again (wet this time).

The deepest instability might just make it as far north as Auckland tomorrow so may be a rare thunder day for us. But the system will be weakening and pulling away tomorrow.
Problem with these blustery unstable air flows is its hard to get the mesoscale forcing to produce strong storms as the sea breezes/convergence are wiped out by the strong flow.
Some of our showers tomorrow look like they could be squally tomorrow, well I think so anyway.
Interesting on one of the GFS models, has a quite intense cyclone coming across the North Island late next week. Other models look to be agreeing on some rain late next week, but I think a full blown cyclone will always seem unlikely.
That low off the SE canty coast is wrapping itself into a gnarly looking storm...will be interesting to see the precip come in again...too bad this isn't winter (?)
, I was only interested because the rain rader seemed to show convection occuring up there too, ill keep an eye on it none the less though
