Another warmer than average day today for most regions around New Zealand, this rings true especially in the east. Canterbury will see a cool down from mid afternoon as the flow turns onshore, cloud about South Canterbury gradually spreads northwards through the region bringing cloudy skies to most before midnight. This cloud starts to break away overnight. The warmest highs are for most of the North Island, in the late teens or early twenties. The coolest highs are for Invercargill and Dunedin on 13 to 14 degrees.
Cloud free skies and anticyclonic conditions bring cooler than normal overnight lows for a large chunk of the North Island tonight, some fog may even develop by dawn on Saturday about some inland North Island parts. A similar story for the upper South Island then as we head south of about Banks Peninsula overnight lows are average for this time of year. Cloud and showers bring warmer than normal overnight lows to Fiordland. The coldest overnight lows will be about the inner South Island (particularly about the main divide), getting down to between 2 and 6 degrees.
