Some parts of the country, including the West Coast of the South Island and Fiordland, are expected to miss out on he warm weather completely however. Metservice predicts two troughs are on their way bringing rainfall, snow and strong winds to parts of the South. Tomorrow a trough is forecast to move slowly east across the South Island preceded by a moist north-to-northwest flow, then followed by strong, cold and disturbed southwesterlies. This trough delivers periods of rain to western areas, and the heaviest rain is expected along the South Island's West Coast. This trough should bring further rain to the west of the South Island, with low confidence of warning amounts of rain accumulating in Fiordland.
