'Critical' southwesterly this weekend for Canterbury

[tich]

This weekend could be either completely fine for Canterbury, or we could get scattered (somewhere, but not everywhere) thunder and hailstorms. The models are going for a 'critical' southwesterly for the weekend. Which means it'll probably stay fine in Chch, though there's always the possibility of thunder and hail should a southwest change come at the right time - ie late afternoon, preceded by a northeasterly sea-breeze. MetService (in its latest forecast) is going for fine weather for the weekend here (and they'll probably be right).

Yes I'll see what happens the WE, Ben
At the moment I'm not putting out a Thunder-Watch but will do if conditions suit.

There is a nice pool of cb over the SE of SI. Must have been some hail down that way today. Midday freezing level at Invercargill was around 1200m, thickness 5319. That cold pool will drift away this evening.

Should be quite stable tomorrow over the SI.

Cracker of a day today after yesterdays gales.Temperature in the early twenties.
Go the AB's

I'll second that. AB's are the better team so here's hoping.

Overcaste with slight drizzle here.

After being fine for most of the day, cloud thickened from the west late afternoon (Akaroa area), but came to nothing. Partly cloudy now, but the clouds not threatening to deliver anything (though isolated showers predicted for tonight).

Only if the centre of the high pressure comes furthur south we hopefully may see some better weather without the rubbish from the SW flow Only if....

Yes .. later in the day some boring weak castellatus froms developed in the Sc cloud that formed. Despite the weakness of the cloud, probably due to a rising barometer and stable air aloft, and the fact that the fresh Ne died away in the evening, I didn't expect anything although a few drops did fall around about 10pm here.
Next Thursday conditions look likely for another Thunder-Watch warning but will wait until we get closer to the day before issuing a Thunder-Watch.

It was cloudy this morning around Akaroa, with even a few (miniscule) spits of rain later in the morning. But it's only been partly cloudy this afternoon; some of the clouds have looked quite dark, but that's probably due to sunshine on them.
