We have warmer weather coming in this weekend as an enormous high near the Chatham Islands drifts away from us and pulls down sub-tropical N to NE winds.

On Sunday these winds turn more N to NW and will make for a warm night and day. It’s all ahead of a cold front connected to the remnants of ex-cyclone Trevor which will bring in some rain to NZ on Monday.

The totals vary across the country so we take a look at the forecast rainfall accumulation between now and next Tuesday.

High pressure returns by Wednesday and lasts until next weekend.
