New Year Thunderstorms

Unread post by NZ Thunderstorm Soc »

MS is posing a moderate risk for thunderstorms in the high country of Canterbury for tomorrow, which according to their models, looks good for the TC area. Hope it is better than the Christmas scenario which brought, nothing here but it delivered that hailstorm to the Motueka area.

Was a small mid-afternoon thunderstorm near Amberley on the 27th also.

The colder upper air over the South Island and a slow moving front over the North Island with moist subtropical air.

Severe thunderstorm watch issued by Metservice for southern Canterbury plains, high country and north Otago. Just missing me to the south. Looks like tomorrow will be a better day for me to chase from my lounge room window 😂

Nothing much happening here at the moment but south Otago does look quite wet according to their new radar.

Actually first 3 days of the year has thunderstorm/hail set ups for most of the country including Canterbury.
I am currently in Hanmer Springs so a good zone today for where the convergences are, will be much better late this afternoon into the evening I think.
The zone shifts slightly more SE tomorrow but I'm thinking given where the convergence is we may see isolated storms possibly severe around inland from Rakaia gorge north into North Canterbury and Marlborough.
45kt upper jet through here too, and things tend to form ahead of the main occluded line to the south.
This line might also have a few embedded storms on it like what's happening today through South Canterbury.
Christchurch and the coast looks better for Sunday afternoon evening on a brief SW flick.
Upper air hovering - 22c to - 25C so still good for summer, but the upper jet and convergences is what we need to watch in terms of hail size and maybe rotation in slow moving storms.
I'd have the severe risk in the areas I just mentioned above.
Happy new year everyone, and cover those crops.
Canterbury, home of good rugby and severe storms

If I was still in Timaru I would be targeting Fairlie to Geraldine today.
GFS also likes the Molesworth station area.

Molesworth cob cottage campsite would be a great area to watch a storm if anyone can get up there, just camp on the higher ground!

Something is happening down there. Just came back for a look. Sadly too much lower cloud is moving in. Few sferics on the radio.

Warned storm heading for Geraldine then Temuka, another coming off Mt Hutt looks interesting on radar.

Yes, hearing those ominous rumbles, as well, Andrew. Too cloudy though to venture out and have a look. All seems to be in the cloud.

I see the severe thunderstorm watch has now been extended to include Ashburton and areas further west and north. Just had the newly warned cell pop up on my phone as I type this.

Thunder has now eased here. Was of the elevated type as you could hear it high up in the cloud.
Wind gone more Southerly here with low cloud moving in from the south. Temperature dropping away as well.

Is anyone planning on chasing in Canterbury tomorrow? I see metservice have added small tornadoes possible to the outlook. Could be some photogenic storms about.
