Cold southerlies cover New Zealand on Friday, meanwhile a ridge starts to sneak in over the lower South Island. Also late afternoon / evening an upper trough may deliver a period of heavy showers about the upper North Island.

Morning showers clear about the upper North Island then late afternoon / evening showers may re-develop before clearing again later on. If these showers develop they may be heavy for a time. The Bay Of Plenty is looking to remain fairly dry afternoon onwards. Southwesterly winds tend southerly during the afternoon and evening.

Morning showers clear about the lower North Island in the west although there may be a spit or two push through at times till evening. Some sun may break through at times from afternoon. Breezy south to southeasterly winds, strong at times about Taranaki.

Showers ease becoming few and far between from afternoon about the eastern North Island, becoming more restricted to the coastal fringes in the evening. A few snow flurries may lower to 400m (perhaps 300m for Wairarapa), only just a dusting about the ranges if anything. Gusty cold southwesterlies develop in the morning.

Mostly cloudy for Wellington, the odd shower possible from afternoon, more so in the east with the chance of a few snow flurries to 400m also. Any snow is more then likely to cause no issues, just a dusting if that. Brisk to strong southerly winds.

Any early showers clear about Nelson / Marlborough then sunny spells increase. South to southeasterly winds (fresh about the Marlborough coast) ease later in the day.

Showers, mainly about the coast and parts of North Canterbury ease during the day then clearing overnight, snow flurries to 200m, perhaps 100m at times. Sunny spells about South Canterbury and perhaps inland Mid Canterbury. Cold southwesterly winds.

Mainly sunny along the West Coast with any early cloud clearing, southeasterly winds ease from afternoon. Cloudy areas about coastal parts of Southland / Otago with the odd shower and low level snow flurry (200 to 100m, snow will basically be a non issue), clearing by evening. Expect long dry periods also with some sun at times. Inland areas are mainly sunny and dry after a very frosty start, further heavy frosts again overnight. Southwesterly winds.
