Humid northeasterlies on Saturday, becoming breezier for the North Island with a large low in the Tasman Sea moving closer. A northeasterly airflow continues on Sunday and eases up a little with a low remaining in the Tasman Sea.

Morning rain (possibly heavy) for Northland and Auckland then easing to showers, showers may become heavy with thunder from afternoon for Northland. Showers about the Waikato and Bay Of Plenty turning to rain by midday, rain may be heavy about the Bay Of Plenty then easing there in the evening. Northeasterlies blustery about Auckland. Cloudy areas along the east coast, chance of a shower, more likely from evening. A few showers in the west, morning rain about Taranaki then easing. Occasional showers or some rain at times for the West Coast of the South Island and about Nelson, falls a bit more scattered the further east one travels. Once again late afternoon / evening isolated thunderstorms may develop about parts of Southland and Central Otago.

Showers for many North Island regions on Sunday, it may be mainly dry to start in the west from Taranaki through to Kapiti however. Showers spring up in the afternoon for these areas and further north, becoming heavy with a risk of thunderstorms then easing later in the evening. The South Island sees a shower or two for most although staying mainly dry in the east. It’s in the afternoon showers become concentrated to inland areas especially about the high country / main divide, showers may become heavy with a risk of thunderstorms for inland Southland / Otago and there is also now a reasonable chance this may occur up into the Canterbury high country also since these maps have been drawn.
