We have a frontal system crossing the North Island during the day, while a northwest windflow precedes it, then changes south to southwest behind it.

This front weakens as it moves northwards, though it will linger to the north of the North Island, and come back down in some way over the upper North Island – perhaps during the weekend.

There’s some morning showers in the west of the North Island (Taranaki southwards), while sunny areas develop in the afternoon as northwesterly winds change southerly.
In the east, a southwest change moves through Wairarapa first, hitting Hawkes Bay in the afternoon, then Gisborne by evening.
This change brings a few showers with it, along with high temperatures earlier in the day.

Northland, Auckland, Waikato and the Bay of Plenty look mostly cloudy, with northwest winds, a few showers in the afternoon as winds change to the southwest, clearing in the evening.

For the South Island, a few morning showers clear on the West Coast, then the odd sunny area breaks through from afternoon, along with southwesterly winds.
The odd morning shower clears Canterbury and Marlborough, staying fairly cloudy in Canterbury, with south to southwest winds dying out in the evening.
Remaining cloud breaks up late in the evening or overnight.
Marlborough on the other hand may see some sun in the afternoon.

For both Southland and Otago, sunny areas increase from morning, while west to southwest winds ease during the day.
