High air pressure which has dominated our weather since the start of Labour Weekend is now finally weakening and about to move out into the Pacific – and with it the sunny, settled weather.

WeatherWatch.co.nz predicts the high, which yesterday was the strongest on the planet, will give the country another 24 to 72 hours mostly dry, sunny, weather before a cold front moves through.

Rain is predicted up the West Coast on Wednesday or Thursday, crossing the North Island on Thursday or Friday.

A sou’west change is likely behind it.

But WeatherWatch.co.nz says despite signs La Nina is coming to life, with lows now popping up north of New Zealand, another large high looks likely to move back in by the weekend.

One long range computer model suggests we are in for several dry days again but there is a hint a sub-tropical low may impact Northland by next Wednesday.
