"There are some chilly temperatures around this morning, but they should return to normal this afternoon," Mr Glassey said.
"It's looking like a dry day for the majority of the country."
Westerlies would start to pick up on Friday with rain spreading into the south-west of the country as another front moves in, he said.
Heavy rain could be possible for Southland, Westland and Fiordland with severe gales in eastern parts of the South Island as well, but MetService has not issued any warnings at this stage.
The front would ease as it moved up the country, Mr Glassey said, but could bring showers and rain to some of the North Island.
Auckland could expect a cloudy and breezy weekend with a few showers expected on Sunday, he said.
"By the time it gets to the North Island there's not a lot of rain with it.
"There will be a little bit of rain in the west of the North Island late Saturday and into Sunday, but not huge amounts, just light rain," Mr Glassey said.
WeatherWatch head analyst Philip Duncan said the high over a number of regions today would be "short-lived".
A spring front would bring heavy rain to the South Island from tomorrow but would be fast moving enough not to cause too many headaches for people on the West Coast, he said.
The upper North Island would see the most settled weather this weekend, he said.
