On Wednesday we have a north to northwesterly airflow lying over New Zealand, while a front moves onto the West of the South Island from afternoon, then slowly pushes northwards.

In the west of the country it’s a mainly cloudy day, while those in the east of the North Island can expect sun and some high cloud.
High cloud is also likely for the South Island in the east, which gradually increases during the day.

There is the risk of a light shower at times in western regions of the North Island, but overall it’s expected to be mainly dry – a higher chance of rain moves into Taranaki overnight.

For the South Island the only rain really about is for the West Coast, and a few spill over showers reaching into inland Central Otago in the west.
