Wet weather is expected to return during the second half of Saturday, potentially affecting the One New Zealand Warriors’ clash with the Gold Coast Titans at Go Media Stadium.
Showers may linger into Sunday, when Auckland FC host the Central Coast Mariners at Mt Smart, though Ferris said it was too early to be confident about the timing.
Wellington is expected to remain largely sunny today, reaching a high of 17C, but there will be a “noticeable northerly breeze”.
Rain is also forecast to arrive overnight and carry into Saturday and possibly Sunday, Ferris said.
Christchurch is forecast to reach a high of 19C today with the odd early morning shower and possible heavy showers about the Banks Peninsula this afternoon.
A front moving up from the southwest will bring strong winds from the afternoon.
A little rain may arrive on Friday as another system moves up the West Coast, but Ferris said totals are expected to be light and Christchurch could see the best weather of the main centres this weekend.
Further south, strong winds and wintry conditions are expected to sweep across parts of the lower South Island today.
MetService has issued a strong wind watch for coastal Southland, Stewart Island and coastal Otago south of Oamaru until 2pm, with gale-force west to southwest winds forecast to spread northwards before easing later in the day.
Ferris said the gusty conditions could bring bursts of heavy showers along the coast.
“There is going to be quite strong winds overnight... and from mid-morning into the afternoon it could be quite gusty around that coast,” he said.
“It could also bring with it some heavy showers, potentially even some hail, because we’ve seen some cooler air coming in.”
The blustery conditions are expected to ease into Friday, with winds turning more northwesterly and only scattered rain expected.
Looking to the weekend, Ferris said the lower South Island may avoid the worst of the unsettled weather affecting the north.
“There’s not too much around on Saturday – just some lingering bits of wet weather that might not come to anything,” he said.
“Sunday is a little bit less certain, with the possibility of winds coming onshore.”
