Much of the rain will be light to moderate with a few isolated downpours. Cooler air moving in across today and tonight.

SOUTH ISLAND:
A cool and mainly dry day across the South Island today. Some wind and cloud through Cook Strait and maybe the chance of a shower there. Southland has some coastal cloud with maybe a shower around Stewart Island. Dry and sunny elsewhere.
