Massive high pressure near Tasmania is bringing in a colder southerly for NZ today and that means frosts over the next couple nights for inland areas of both islands.

It may not be until tomorrow night/Friday morning that it affects more of the North Island. The big Aussie high will finally reach NZ this weekend and early next week bringing more cold nights and fairly calm days.

Next week there may finally be a break in this high pressure pattern due to two reasons explained in the video at the end: 1) High pressure looks to be finally tracking further northwards next week and 2) There’s a low trying to form in the Tasman Sea. However, high pressure is still dominating NZ’s weather as we go into next week.
