Low pressure remains stalled over the North Island and while it’s a fairly weak low it’s combining with that colder southerly flow over the South Island.
The mix of warm and cool air masses continues over the North Island encourage big afternoon downpours inland with isolated thunderstorms, again possibly severe.
Meanwhile the South Island is again smothered by a fair bit of high pressure, especially in the southern half. Further north and rain brushes Marlborough with showers and drizzly spells around Nelson and North Canterbury.
The South Island also has the most extreme difference with temperatures compared to normal as eastern areas deal with the colder, cloudier, airflow and western areas push up over 8 degrees above normal.
