The final weekend of summer looks set to bring fine weather to some parts of the country and downpours to others.
Philip Duncan of WeatherWatch said the weekend looked fantastic for a number of areas.
However, the tropical air flow left over behind ex-cyclone Winston would bring some downpours across the North Island.
Mr Duncan said Saturday would be generally dry in both islands apart from showers along the West Coast thanks to a cold front.
Around Taranaki, a humid tropical flow would meet a colder southerly flow sparking downpours from Saturday into Sunday.
The east coast of both islands would be dry with the sunniest weather in the North Island's east, said Mr Duncan.
Cloudier spells were likely on the South Island's east coast.
Mr Duncan said Sunday would bring downpours across the North Island in the early hours, particularly western and central areas.
There would be a mixture of tropical downpours, cloud and light drizzle with very high humidity in the upper north.
As the day went on and the tropical heat increased there might be even bigger downpours developing, he said.
The humidity would ease for areas south of the lower North Island and thunderstorms were possible too.
MetService communications meteorologist Lisa Murray said a westerly flow across the South Island would bring rain to the West Coast tonight, some of which would be heavy.
Those fronts were would also affect the southern part of the east coast of the South Island, which might receive some scattered rain this afternoon or evening.
She said the North Island was mainly fine today with a bit of a cloud but could expect "the odd spot of drizzle" this evening.
Some strong winds were today affecting Manawatu, Wellington and Wairarapa.
Ms Murray said humid air moving over the country would bring overnight temperatures of 20C to 21C in some parts of the upper North Island over the weekend.
The Wellington region and upper South Island would receive overnight temperatures of around 18C and conditions would be muggy and humid.
The warm, humid air would bring rainfall, arriving in western areas tonight.
Ms Murray said the South Island would receive a mixture of wet and dry weather over the weekend and the weather would be fine in eastern areas of the South Island.
Ms Murray said the risk of Tropical Cyclone Winston directly impacting New Zealand was diminishing day by day.
Another tropical cyclone named Yalo had developed near the Cook Islands north of Rarotonga. It was a category one tropical cyclone, which was the weakest type of tropical cyclone and not expected to intensify.
