Detailed Antarctic Blast Update — A significant wintry blast is moving into the country and brutal wind chills from the Antarctic region are coming in.
In this video we display something brand new – the Misery Index – which shows wind-chills of -15 to -25 possible around alpine parts of the South Island.
Meanwhile the bitterly cold air with run into heavy rain over the central and eastern North Island – with very heavy snow about the plateau and eastern ranges (watch for road closures), heavy rain in the east and gales in the south and west.
Itâ€™s a rough Saturday for the North Island with major frosts hitting the South Island overnight and into Sunday. Itâ€™s a very busy forecast – Philip Duncan has the latest on New Zealandâ€™s weather.

These are “Thickness Lines”. And they are pretty much that, they represent how thick the atmosphere is but it’s made up through a combintion of a few different figures. The red and blue lines are nothing special in themselves but just represent where colder air and warmer air is generally speaking. Here is a big explanation on thickness lines:
