An area of low pressure gradually draws in a southerly airflow over the South Island on Wednesday.
Most regions around New Zealand can expect some rain or showers for a time on Wednesday but nothing is overly severe or terribly cold. Conditions will start to cool down a little for the eastern South Island as a southerly airflow slowly makes its way northwards over the South Island during the day. The West Coast of the South Island gets some good weather from afternoon after morning showers clear.
