NZ: Low pressure moving in, east coast storm likely by Monday (12/2/26)

There is still some disagreement in forecasting computer models about precise timing and placement of a stormy low that has the potential to create widespread severe weather. The low, which is expected to grow and power up over Sunday and Monday is due to a number of smaller, weaker, lows all merging. This can be a complicated process and makes it tricky over a mountainous island nation to be precise in advance - this is because subtle changes can have big consequences region by region, especially due to our mountains and ranges. In today's video we show you the world's two leading computer weather models and compare them for this Sunday and Monday and why those in the north and east of both main islands need to monitor this one - even if the weather doesn't pan out so severe, the potential is certainly there. Wet weather chances and isoated thunderstorms are also possible in both main islands today, Friday and this weekend. More high pressue is expected next week, likely settling things back down again. We also compare European and American models for 7 day upcoming rainfall. For those that ask why we don't include NZ modelling that is because government agency Niwa (Now also known as Earth Sciences New Zealand) won't share their data with others, as the NZ Goverrnment has commercialised that public asset.
