The weather forecast for New Zealand this weekend is a mix of sun, cloud and rain with a disorganised and slow moving low pressure system forming in the Tasman Sea.

Air pressure over the North Island remains high so approaching fronts attached to the Tasman low will weaken as they push in to it.   

Rain is likely to be heavy along the South Island’s west coast but as the front falls apart as it heads north it will weaken with only light showers or drizzle expected morning and night in Auckland and Northland.

Cloudy conditions are likely across many regions in the north, centre and west this Saturday and Sunday with light showers or drizzle quite likely on Sunday. 

Eastern areas may well remain mostly dry.

On Sunday the low, with a central air pressure of only 1009hPa (hardly even a low) will slowly drift towards New Zealand while a high will form east of the lower North Island coast.

Early next week the low is likely to bring more showery weather to the west.
