Improving weather trend for the rest of the week

April 28, 2015

After a wet and windy start to the week, the weather should gradually improve and become mostly fine by the time the weekend rolls around. “There is still a bit of the wet stuff around for the next couple of days, but the trend is for fine weather to dominate by the end of the week,” commented MetService meteorologist Stephen Glassey.

An area of low pressure moved over New Zealand during Monday and early Tuesday, bringing heavy rain and strong winds to many areas. “All the main centres have seen a decent dumping of rain with parts of Wellington receiving over 50mm since midnight Sunday. Northerly wind gusts also reached over 100 km/h around Auckland’s harbours on Monday night,” Glassey said.

As the low moves away to the east today, it leaves behind a cooler southwest airflow with showers still affecting many areas. The southwesterly winds are forecast to strengthen during Wednesday, with the strongest winds expected around the southern coast of the South Island between Bluff and the Otago Peninsula. A Severe Weather Watch has been issued for the exposed parts of Southland, Otago and Banks Peninsula, as well as Hawke’s Bay and Wairarapa between Masterton and Napier.

Clear skies and colder temperatures across the central parts of the South Island will once again bring the risk of some cold and frosty starts this week. Temperatures about the North Island’s central plateau are also likely to drop down this week with some chilly nights expected towards the weekend.

The showers should disappear from most places later in the week as a high in the Tasman Sea approaches, moving over the country this weekend. “It’s looking like a fine weekend and start to May for most of New Zealand,” said Glassey.
