Cold blast number 1 arrives, cold blast number 2 is on the way (+4 Maps)

The first of two significant polar blasts is today covering New Zealand bringing thunderstorms, hail, snow and miserable conditions to those outdoors.

Mostly or partly sunny weather is dominating the east of the North Island and many parts of the South Island due to the air flow and the mountains/ranges blocking some rain clouds. If this hasn’t happened yet it may happen later this afternoon as the North Island cold front moves away from the island.

Temperatures are lower than usual in most areas. Minimum temperatures are much more significantly affected with overnight lows possibly down to -8C in Queenstown tonight, -3 in Wanaka and -4 tomorrow in Alexandra.

Today New Zealand is located behind the cold front but another cold front is approaching to bring more snow, rain, wind, hail and thunder from late Thursday and across Friday. This next front will be as strong as the last one on Tuesday/Wednesday and will again cause NW gales over the interior and eastern South Island during Thursday daytime and later into Cook Strait and Wellington/southern Wairarapa. Although the amount of rain accumulation is lighter than the last event, snow accumulation is as heavy as the last event and is expected over mountainous regions.

From Thursday afternoon, snow or mixed precipitation is possible even lower down just west of the Southern Alps. The front will sweep the South Island northward and eventually bring thunderstorms in western and northern parts of the North Island from Thursday night and across Friday.
