A cold southwest front moves northwards over the South Island today reaching the lower North Island late afternoon. A ridge brings some settled weather for a time on Wednesday, overnight however a front stretches out from a low in the Tasman Sea bringing some rain to the upper North Island. A low sits out to the west of the country on Thursday dragging in an east to northeasterly airflow.

Tuesday

Blue – A tad cool to start the day in the areas marked below, no major frosts.

White – A few morning snow flurries to 400m about North Otago / South Canterbury clear, snow flurries continue about Southland and Otago up to about Otago Peninsula bringing flurries down to 400m, perhaps 300m at times then clearing overnight. Snow amounts will not be large but still worth keeping an eye on.

Wednesday

Blue – A rain band pushes onto the upper North Island overnight, easing by dawn on Thursday. Rain is not looking torrential however the odd heavy fall looks possible.

A frosty start to the day for many, especially the South Island where some isolated inland spots may dip into -7 to -8 degree territory.
