A spring surge of cooler air is spreading into the south and east of both islands today, dropping temperatures a little further and pushing showers northwards.
Only a few showers will make it into the very north of NZ today and it’s a similar story in the south of the South Island.
In the middle/central part of NZ rainfall totals are higher with 5 to 20mm possible – and up in the ranges add another 10 to 20mm more to that.
Windy weather will continue in Southland and coastal Otago, and a large portion of the North Island will get a surge of winds too, although nothing too serious at this stage.
