A westerly airflow lies over New Zealand today, within this flow a front pushes northwards over the South Island however it weakens quickly.
Tuesday is quite cloudy in the west, the risk of a light shower or two increases also. In the morning some rain about Fiordland looks to be heavy then easing as a front pushes through.
A mainly sunny day in the east however there will be some morning rain or showers about Southland and Otago then easing.
Any morning showers clear on Wednesday otherwise expect morning cloud breaking to mostly sunny weather, a few showers push into Fiordland later in the afternoon and northwesterlies become gusty about the lower South Island by evening.
