A low from the Tasman Sea moves in to the South Island and western North Island tonight and into Friday bringing rain from the west with some heavy falls and maybe some isolated thunderstorms.

The warm (or mild) nor-east flow turns colder southerly quarter over Friday and into Saturday – then high pressure comes in behind it for Sunday (and this brings a frost risk though the South Island’s interior).

By next week the westerlies return – pushing temperatures up again.

We also take a look at an erupting volcano in Indonesia now causing flight cancellations to Bali from NZ and Australia due to the ash clouds.

*Programming Note: We have no video tomorrow/Friday or next Wednesday due to commercial commitments – but we’ll see you again on Monday.
