A frontal change then moves onto the lower North Island late in the afternoon and into Tuesday evening, then onto the upper North Island overnight.
With this front we can expect rain and showers for both the west and east coasts as it moves northwards, while warm weather and high cloud will dominate in the east before the front moves in.
It’s looking like mostly cloudy skies in the west with the odd shower to start, while late rain will be heaviest in the western quarter with this system.
There does appear to be a low to moderate risk of thunderstorms about Buller and then Taranaki as this front moves through, anywhere from early afternoon through to evening.
