A mainly dry morning for much of the North Island today, areas of low cloud or fog are possible in the morning then again overnight especially for inland areas. A few showers will sit just offshore about western coastal fringes then during the afternoon the odd isolated shower may make it onto land. Mainly sunny and dry in the east. For Nelson, Marlborough and Buller expect some rain for much of the day, showers about Canterbury for most of the day also although drying out in the afternoon for South Canterbury. Snow in the mountains down to 500m. Mainly dry for the West Coast, Southland and Central Otago, coastal Otago sees a light shower or two.
