Wednesday’s national forecast: Sub-tropical fuelled rain for parts of the North Island (+9 Maps)

A trough, or the beginnings of a weak low, will form just to the north west of NZ today and will connect to an area of sub-tropical winds pushing down over the upper North Island.

Most of New Zealand will be warmer than average today with the upper and eastern North Island having another warm night tonight with overnight lows hovering around the late teens, even 20 degrees.

A cooler night is coming for the deep south though.

Rain clouds are most likely along the western and very northern North Island.

This trough, or small weak low, will then cross over the North Island on Thursday bringing additional downpours of rain before clearing in the afternoon and evening.

Here are the regional forecasts for Wednesday…don’t forget to use your local HOURLY forecasts to drill down deeper…
