Tuesday is characterised by a weakening front moving northwards from the South Island towards afternoon, weakening in the process.

The front mainly delivers shower activity in the west, but a few showers brush the East Coast also.
Winds ahead of the front blow from the northwest, before changing south to southwest behind.

For the upper North Island expect westerly winds, and a mix of sun and cloud – with cloud thickening later in the day, before a few showers move through overnight.

For the lower North Island, cloud builds in the west, along with the odd light shower, showers a little more persistent for a time early to mid afternoon as that front moves through.
It’s shaping up mostly sunny in the east with some developing high cloud, and a southerly change late in the afternoon or evening brings increasing cloud and a few showers.

For the upper South Island, early rain eases then clears on the West Coast to a few sunny areas, along with winds from the southwest.
Nelson could see a spell of morning rain, before becoming mostly sunny in the afternoon, while Marlborough sees morning cloud with the chance of a shower then afternoon sunny areas.
Canterbury is quite cloudy for much of the day with southerly winds, while the odd light shower or two is possible during the day.

West to southwest winds blow about Southland and Otago, and Southland sees the odd patchy shower during the day too.
Otago looks somewhat drier, with some sun about now and then, though there’s still the risk of a shower or two here and there.
