The Crown Ranges, Desert Road and the Rimutaka Ranges are all cloaked in snow, so although the sun will be out temperatures will only rise one to two degrees in most places.

The coolest temperatures are expected in Otago and Southland where 6-8C is forecast throughout the day and a freezing -4C is predicted in Invercargill overnight.

Yesterday the warmest temperature in New Zealand was in Kaitaia at only 14.4C, which is the coldest maximum temperature at Kaitaia since September 11 last year.

Metservice meteorologist Ravi Kandula said most of the South Island is set for fine weather and a bit of cloud around the ranges, Banks Peninsula and Otago.

“In the North Island, south of about Taupo, showers are continuing in a southerly flow with more about the coast as you would expect. These will drift as far north as Gisborne and Mahia Peninsula but further north is fine.

“Going into tomorrow, the ridge continues to build and the southerly flow continues over the North Island bringing isolated showers. Within the South Island it is expected to be fine and that trend will hold into Thursday.

“A slight northeast flow will then begin to build over the upper North Island, bringing some showers to parts of Northland and Auckland,” Kandula said.

“But essentially over the next few days we are talking an easing southerly flow, with a ridge building over the country and frosty conditions for many parts of the country. There will be fog for sheltered places as well.”
