Polar outbreak on Monday and Tuesday

A burst of cold air originating from the Antarctic ice sheet is expected to affect New Zealand on Monday and Tuesday. Unseasonably cold temperatures, strong winds and snow to low levels are expected over the South Island where this event is likely to have a high impact. Livestock could be affected and it will probably have an effect on higher roads where significant snow accumulations may make driving conditions difficult and could lead to some road closures.

Winter is coming (for a bit) - updated Friday 10 April 2015

Update by Peter Little, MetService Meteorologist, at 4.30pm

A polar blast due early next week will see temperatures plummet in many places, with snow expected to unseasonably low levels over the South Island and lower North Island. On Monday, MetService is expecting snow to fall to 400 metres in the far south of the South Island and to 600 metres on Banks Peninsula. Early Tuesday, snow is expected to lower to 900 metres for a time on the Tararua Range.

Winter is coming (for a bit)

For much of New Zealand it was a warm Easter break with many places recording temperatures well into the twenties. On Easter Sunday, 5th April 2015, the warmest spot in the country was Kawerau in the Bay of Plenty when the thermometer reached 25.7°C. However, as we look ahead to this weekend the forecast looks very different, with cold air spreading across New Zealand from Sunday.

What’s the forecast?

Cyclone Reuben crossed latitude 25 South overnight last night, with the Wellington Tropical Cyclone Warning Centre assuming high seas warning responsibility for the system this morning. As Reuben continued to move southwards it weakened, and at midday today (NZDT) was re-classified as an extra-tropical low.
