NIWA predicting a colder than average September with disturbed weather.

Caused by the stratospheric event discussed on the other thread.

Should be an interesting month alright,

Yes, there some mention of this on the wireless this afternoon.

22 degrees at the moment for Ashburton after a predicted high of 17.Much warmer inland than the more coastal towns.

17.7C at Thornbury currenty

21.4 in Chch, above both the Metservice (18) and NIWA (20) predictions. A stunning weekend of weather.

22 degrees in some parts. Felt almost like summer rather than first day of spring

Topped 20C here.

Yes a lovely day alright, 22.8 here, but I did drive through a pocket of 24deg near the Hurunui pub

Perfect reason to pull in and part up out the front with a shandy or two

A low pressure system developing to our north will give the North Island a wet week. And localised downpours/thunder developing in the far north later tomorrow or early Wednesday in areas exposed to NE.

windy and rainy here. weried that the rains coming from the east. i see from rader. the sub tropical low has set in. after yesterday temperatures here went 20 degrees celcius. bit cooler today.

Tonight’s run of EC now predicting 2-4cm of snow to sea level in Canterbury Sunday into Monday, kinda snuck up on it this one with all the SSW talk!

The weekend has been looking cold for a few days, Ben Noll and Chris Brandolino from NIWA we’re mentioning that in their outlook. Bitterly cold air coming up from due south.

tommorow afternoon metservice has us in the moderate risk that goes from northland to waikato . in the afternoon. and the low pressure spreading. maybe a isolated thunderstorm?

this is the first ECMWF run to have this outcome. We need to keep tracking over the next few runs to see if there is any constency there, or just a rogue model run. Only a few of the ensemble members are currently showing snow to that level.

20mm in my rain gauge yesterday. Very mild night with 14C min

24mm so far for here.

A drizzly start here with a very low cloud base, so low the tops of the pylons and in the cloud

a few trees blew down last night from the wind

Kataia had a thunderstorm very early this morning with the PWS there getting over 25mm in an hour.

Looks like a trough line will be coming south later today but at this stage I think it is a just low thunder risk in Auckland. But I will be keeping an eye out.

metservice has it moderate. but i will keeping a eye out too. especially in the afternoon. yes i saw that storm on radar. did weaken slightly when it hit land.

Currently 995.1 hPa here. Interestingly the top of the NI at Cape Reinga is down to 985 hPa on the MS reading, that is 3 hPa lower than EC and 5 lower than the GFS 18Z projections.

edit: the low's circulation is moving slightly offshore on the west coast. Seems like it currently is deeper than expected. Might mean a tighter gradient for tomorrow night's south westerly wrap around into Auckland.
