Enjoying the warmer weather here also, already 17C here.
I think the bitterly cold air in modelling east of NZ next week is something to watch, parts of NZ may well end up catching some of that.

yes, going to be warm again
was 1.5C warmer than normal here for the 24 hours for the day yesterday than normal
which is negating the colder days earlier in the month
the sea breeze only made it onto the coastline here yesterday, real late too, at around 6pm

Lighter flow today so seabreeze convergence is more likely , isolated afternoon showers under the sea breeze line.
Currently fine here, 20C, dewpoint 13C

looking far more likely of getting a storm here today going by MS latest outlook.
RE yesterdays storms. A firend on the Napier Taihape road had a 2hour thunderstorm yesterday with torrential rain about the area.

Looking like eastern places (Gisborne/Napier) will be the best spot for thunder today. But some cb's also developing further inland toward BOP.
18Z Lifted index chart here for 4pm today with surface wind flows included.

Some Cumulus developed here around 10am although reasonably weak went up fairly fast with a few light showers around midday at work, i see one of the showers may have been a brief thunderstorm up near Waikari North Canterbury going by the hourly radars.
Not bad for a weak front really might be catching some of that cold unstable air Australia has been having.
Next week could be interesting with a few fronts here and there.

Possibly some very warm upper air moving over NZ in a week, though the models could still change...

Yes, possible warm air off Australia early Dec.
Might be some cold weather around thurs but GFS is keeping this east of NZ at this stage.

I like the bath out in the middle of the paddock. An unusual feature for a thunderstorm photo
