Subtropical winds will lift temperatures over 8 degrees above average for some parts of New Zealand this weekend (compared to what is usually recorded at this time of year – it may still feel cold though).

Where specifically large high pressure zones are centred matters a lot. Think of them as giant anti-clockwise roundabouts in the sky, but instead of traffic it moves air. The high pressure zone east of NZ is going to pull down subtropical air, therefore making many places warmer than usual – along with a low pressure zone forming in the southern Tasman Sea which will help ramp up the nor’west flow this weekend.

Put short, northerly quarter winds ramp up more (and turn more north-west) on Sunday as a cold front approaches bringing a band of rain, hopefully into some dry regions, across Sunday and clearing Monday morning.

This coming week – it’s a whole new ball game. Low pressure, westerlies, southerlies and subantarctic air may produce severe winter weather later in the week.

⚠️Friday's forecast is messy for NZ.

Fun fact: For a major Antarctic blast to hit NZ (like 2011) the low pressure zone needs to be south-east of Dunedin/South Island, NOT north-west over the Tasman Sea. This setup pushes the coldest air over the Tasman. *Might still change* pic.twitter.com/og8ttgvCYY

🌡️Most of #NewZealand is much warmer than average for this time of year. Some over 8 degrees above normal this weekend (#SubTropical winds pulled down due to high pressure east of NZ).

SUNDAY:
Here comes the cold front – but before it arrives for most regions a much warmer than normal airflow (for this time of year) will move in from the subtropics … and if you don’t have the subtropical part you likely have a windy nor-wester. Either way, Sunday is shaping up to be warmer than usual.

Rain sets into the West Coast and heavy falls are possible. Rain moves into the North Island later on Sunday or overnight and into Monday morning. A few isolated thunderstorms are possible as the cold front moves in.

Check your local forecast for rainfall possibilities and totals, and hourly temperatures. All our forecasts are updated hourly.

MetService warnings are possible this weekend.
