A low pressure system sits over the tip of Northland on Tuesday draging a south to southeasterly airflow over the North Island while the South Island is mainly settled due to a ridge of high pressure.
For the North Island we see some rain about northern parts of Auckland and Northland during the day, there is the chance of a heavy fall here mainly in the east. Overall though torrential falls are not expected. Winds for this part of the North Island may be fairly gusty during the day from the southeast also.
The odd shower peppers the east coast from Gisborne down through Wellington during the day, there may be a light snow flurry with any of these showers down to 500m however they will only be minimal with little to no accumulations likely. A touch of frost to start the day inland and a mainly sunny day ahead in the west.
For the South Island it’s a quite settled and sunny picture, a bit crisp and chilly though. Heavy frosts to start the day especially inland, black ice may be of concern. Just a touch of cloud in the morning Banks Peninsula northwards along the coast which clears away.
