A large high is moving in from the lower Tasman Sea, but on the eastern edges of it is a southerly change and this means temperatures will drop for some, especially in the lower South Island.
A few showers may affect the South Island today, especially coastal areas, but the day should be mainly dry, particularly this afternoon.
Meanwhile the top half of the North Island continues to see tropical air sitting around – creating more localised downpours.
Upper North Island
Showers, some heavy and slow moving into the afternoon, especially around Waikato region. Humid again but humidity may ease by evening. Heaviest downpours from around Auckland southwards.
Lower North Island
Westerlies blow for much of the day and mostly dry – but a few brief showers about, especially as a southerly change arrives afternoon or end of the day bringing a cool change. Heaviest downpours north of about Taranaki.
Upper South Island
A cool southerly change is moving northwards and may bring a few coastal showers into the east. The day dries out though – and the cooler winds mean a cooler night on the way.
Lower South Island
A cooler south west wind blows through, brisk in exposed areas. A few brief showers, mainly around Southland or coastal Otago. The day dries out as it goes on – with a colder night tonight. Strongest winds in the south eastern corner, from about Dunedin to Southland.
