“The wetter half will be the western half of the country, similar to yesterday, but then those fronts will be moving across the country, so the rain will also spill into the eastern areas.”
Buller to the south, the Coromandel, and from Kāpiti to Auckland were most at risk of stormy conditions from this morning.
“In the afternoon, it will only be confined to the South Island, so all the western areas, including southern parts of Southland and Clutha.”
While there may be longer spells of sunshine and dry conditions to the east today and tomorrow, Shiviti said these will largely be short-lived.
As the unsettled weather spreads, temperatures are expected to remain fairly chilly for the next few days after unusually high averages last week.
“Whatever temperatures they saw tomorrow, it won’t be too different to what they’ll see today and the following day,” Shiviti said.
Most areas won’t get past the high teens to early 20s today, with cool lows expected to remain over the weekend.
“By the end of the day on Friday, overnight temperatures will start climbing up, so I think places like Whakatāne and Taupō will be getting overnight temperatures of about 14 to 15C.”
The possibility of thundery conditions will be heightened over the weekend, with a “large and complex low-pressure system” set to cover most of the country by Sunday.
“The low-pressure system is expected to bring rain or showers to many parts of New Zealand, with thunderstorms also a possibility in northern and central areas of the country,” MetService warned.
