An incoming front, bringing with it a strong westerly quarter windflow, will move across the country from the Tasman Sea on Wednesday, changing our weather patterns for the second half of the week.

A strong northwesterly airflow will move over most of New Zealand, while that front moves northwards over the South Island during the day – reaching the lower North Island later in the evening.

Fairly cloudy skies cover the west of the North Island, bringing showers – mostly from afternoon – though some move into Northland from morning.
High cloud thickens along the East Coast, with a few spots of rain incoming later in the day.

The South Island sees rain on the West Coast, with heavy falls at times.
The east coast has thick high cloud, while a few spots of rain may pass through at times, along with gusty winds from the north or northwest.
Southland and Otago, meanwhile, see showers from late afternoon and into evening – with a chance that one or two may be heavy.
Winds tend northwest generally, but will be onshore for a time about coastal Otago.
