A large low out over the Tasman Sea is set to bring areas of rain, downpours and some thunderstorms over the coming days as the low moves in – but then falls apart over the weekend.

Colder and drier air remains in the south – and that colder airflow moves up into the lower and eastern North Island going through the weekend and the start of next week.

Despite some showers lingering next week, high pressure out of Australia is expected to grow in the NZ area.
