We’re halfway through this polar surge of air so temperatures will be below average nationwide today and especially tonight.

NORTH ISLAND:
A brief burst of early rain or showers for the eastern North Island with a strong southerly change, similar story for the western North Island around Auckland northwards – then both sides of the island dry out as the day goes on with increasing sunny spells despite the colder winds, but showers may return again later as wind flows continue to shift around, even if only very slightly it can have significant consequences as to whether it will be sunny and dry or cloudy and showery. Wellington and southern Wairarapa are exposed to showers all day with the cold southerly flow. Snow showers continue around the Central Plateau mountains all day and may impact State Highways for a time around Mt Ruapehu in particular. Driest regions today will be eastern Northland and Bay of Plenty.
Highs: 4 to 14

SOUTH ISLAND:
Wintry showers hug the eastern coastline today and at times coastal Southland too. The further inland you are the drier and sunnier it will be. South to South West winds for most. Sunniest weather inland, the West Coast and Nelson and Marlborough.
Highs: 6 to 12
