There’s a lot of variety in the weather today across NZ as the wintry changes in the south continues to move up the eastern side of the South Island and into the lower North Island, while mild northerlies carry on at the top of the nation.

Low pressure remains centred over the Tasman Sea surrounded by high pressure, keeping it all in place – but slowly nudging it all northwards. This means the cold portion of the airflow moves into the North Island over today, tonight and further into Thursday in a weakened state.

Snow is most likely in the eastern hills and ranges of the South Island and it will ease and clear further south. Rain and showers to sea level continue but also ease in the south where skies are drying out ahead of incoming high pressure.

Rain and showers move into the lower North Island today with that colder airflow and a dusting of snow on the ranges. This moves northwards tonight and into Thursday with coldest air in the eastern side of the North Island up to East Cape.

Also for today, Wednesday, there will be sunny and/or areas in the south of the South Island, the West Coast and in some parts of the upper North Island, mixed in with the areas of rain or showers.

Frosts come into the picture for the South Island overnight tonight – and are especially widespread over the next few nights/mornings.

⚠️❄️Moderate to Severe #Frosts are on their way for the South Island from tonight.

For some locations through the interior, in the shade, the frost may linger until next week without melting with daytime highs barely above zero degrees.
