A front weakens over the North Island today meanwhile a ridge brings mainly settled weather further south. A northerly airflow gradually increases on Wednesday. A front moves in from the west on Thursday with a strong north to northeasterly airflow preceding it.

Tuesday

Blue – Rain about the upper North Island may be heavy early this morning then easing away.

A frosty start for much of the inner South Island, generally no major frosts with 0 to -2 degrees most common. -4 isn’t out of the question in some isolated inland spots.

Wednesday

Blue – Another frosty start about a thinner slice of the inner South Island, no major frosts.

Purple – As a northerly quarter airflow increases over New Zealand during the day northwesterly winds becoming gusty through Cook Strait and northeasterlies strong about coastal Fiordland from afternoon.

Thursday

A deep low forms moving into position west of the South Island on Thursday. Hooked into this low is a front which moves in from the west delivering heavy rain about the upper North Island and Nelson / Tasman before easing later in the evening. Rain about South Westland may be heavy then easing from afternoon.

North to northeasterly winds preceding this front are quite strong with gales likely about coastal areas especially about northeastern parts of the North Island.
