A large high continues to sit out to the east of the country today while a warm northeasterly airflow flows over New Zealand. Unstable conditions may develop about the inner South Island this afternoon. The flow remains from the northeast on Thursday although we have a front approaching the West Coast during the day from the west, this front moves over the North Island on Friday.

Wednesday

Blue – Isolated showers about the inner South Island (mainly Mid Canterbury southwards) becoming heavy this afternoon with thunderstorms then clearing later in the evening.

Yellow – Another warm day for most, especially about the lower South Island with high’s reaching into the mid twenties.

The odd light shower affects northeastern parts of the North Island during the day.

Thursday

Blue – Overnight as a front closes in rain may be heavy at times for the West Coast of the South Island.

Yellow – A warm day about the lower and eastern South Island with afternoon high’s reaching into the mid twenties, perhaps even late twenties about the lower South Island. More so about inland areas away from the coast.

The odd light shower continues to affect northeastern parts of the North Island during the day.

Friday

Morning rain (possibly heavy) for the West Coast of the South Island eases. As a front settles over the upper North Island in the afternoon showers or areas of rain may turn heavy at times however this will become clearer over the next day or two as we get closer to Friday.

Northwesterlies gusty / strong at times about the inner eastern South Island in the afternoon, also through Cook Strait. High’s reaching into the low to mid twenties in the afternoon for the eastern South Island.
