A humid northerly flow is spreading across New Zealand with sub-tropical connections.
Low cloud, rain setting in, hotter weather inland and in the South Island. Tonight will be a warm night with some places having overnight lows very similar to their daytime highs in the north where humidity and low cloud keep it a little cooler by day but then locks in the warmth at tonight.
The sub-tropical northerly flow covers most of NZ and may be a little windy in some areas, like Auckland and the upper North Island, also around the Southern Alps.
