InfoGraphic: The Main Weather News Highlights across NZ: Wed, Thu, Fri

Today sees a very cold southerly airflow cover New Zealand with a low deepening later in the day east of the North Island. A squash zone develops between the low about the eastern North Island and an incoming ridge in the far south on Thursday creating very strong winds about central New Zealand and some heavy rain. Friday sees a ridge slowly make some headway over the South Island while strong south to southeasterly winds ease later in the day over the North Island.


Blue – Rain heavy for a time about Taranaki in the afternoon, about Hawkes Bay / Gisborne in the evening and overnight. Rain about Wairarapa, Wellington and perhaps Manawatu becoming heavy overnight.

White – Bitterly cold south to southwesterly winds bring snow flurries to low levels (200 to 100m) at times for much of the southern and eastern South Island. Flurries may reach to near sea level at times.

Snow flurries about the Central North Island to 700m at first then lowering to 400m or perhaps even 300m in the afternoon, clearing in the evening. Flurries about the Wellington region to 300m clear around midday. Some snow lowers to 300m for a time about the Wairarapa, 500 or perhaps 400m about Hawkes Bay then 600m in the evening for Gisborne about the ranges. Overnight as heavy rain pushes into the Wairarapa with it comes heavy snow to 500m, 400m for Wellington.
