Within the ridge of high pressure over the South Island, a weak, shallow low may form over the interior of the island, this may lead to some cloud building about inland ranges in the afternoon and evening.
This brings with it the chance of a light shower or two later in the day – though mainly this is for the upper half of the South Island.
Sunny areas and southerly winds build in the east of the island, before tending east to northeast in the afternoon.
Cloud then builds about inland ranges, with the chance of a light shower or two later in the afternoon and into evening mainly about the upper South Island.
For much of the West Coast expect mostly sunny weather with west to southwesterly winds.
Sunny areas for Otago, a little cloudier about Southland with the chance of a shower now and then, winds from the west or southwest.
For the North Island, any early showers clear in the west of the North Island – then expect sunny areas with south to southeasterly winds.
Late afternoon may see an isolated shower or two north of about the Waikato.
Along the East Coast, expect morning rain to mostly clear for all – then cloud breaks later in the day, and the odd shower may hang about Gisborne till evening.
