A weak frontal boundary is expected to bring some rain to the western South Island tomorrow.  Rain should develop during the morning hours about Fiordland and then slide up the West Coast.  By noon, the rain may be as all the way into Nelson.

Rain could also develop about the deep south tomorrow.  It’s not likely to be as long lasting or as widespread.  The best chance will be from mid-morning to early afternoon.

The threat for heavy rain does exist for the West Coast.  Government forecaster MetService has heavy rain warnings up for Fiordland starting tonight and lasting into tomorrow.  They are also watching Westland and Otago Headwaters for the possibility that heavy rain will develop there during the early part of tomorrow.

The rest of the country is looking settled and quite mild for tomorrow.  Highs should be at 20 or higher for just about everyone that gets a good dose of sunshine tomorrow.
