A front passes over the North Island on Tuesday moving in a west to east fashion clearing off to the east by late afternoon. A west to southwesterly airflow lies over the South Island.

Morning rain for the western North Island may be heavy on Tuesday then easing to showers and sunny spells from afternoon, dry at first in the east then some rain passes over from the west in the afternoon, clearing evening.

Early heavy rain for the South Island’s West Coast, Nelson and Marlborough then easing. Cloudy areas for elsewhere in the South Island with the odd shower about especially for Southland and Fiordland, just the risk of a shower for Canterbury.
