High pressure will cross over the North Island on Friday and Saturday bringing foggy areas in the north of NZ, but encouraging milder nor’westers in the South Island.

By Monday that high is out east of NZ and a potential wintry change comes into the South Island – but as we said yesterday there are a lot of moving parts to this and it may not pan out as forecast. We explain today two different scenarios – neither of them are locked in.

Sometimes the chaos of the winter weather systems south of NZ and around NZ can make it very difficult to lock things in, in advance – the issue with this set up is uncertainty about the precise shape of the anticyclone over south-eastern Australia, and every change in the forecasts on the shape of this one high dramatically changes the outlook for NZ.  We have the latest – and will continue to cover it in our videos on Thursday and Friday this week.  Put short – next week looks messy in NZ weatherwise, especially compared to how this week is going.
