Temperatures are already above average in about two thirds of NZ and even warmer weather is coming. By Friday night high pressure will move in over New Zealand and linger until next Tuesday. As it moves over us it will bring cooler nights with lighter winds but the afternoons will be mild, especially Sunday to Tuesday as sub-tropical winds kick in.
By Monday and/or Tuesday the sub-tropical northerly flow should cover much if not all of the country pushing temperatures up above normal in most places by day with overnight lows also lifting up.
Places like Queenstown look significantly milder than the single digit highs of recent, with highs into double digits from Saturday. Through Central Otago overnight lows are close to frost but many areas look to hover just on the warmer side of +1 which indicates if frosts do form they will likely be quite light.
In the North Island Saturday night may be a cold one with low single digit temperatures, for example Taupo drops to +1 and Hamilton +2 when you wake up on Sunday but by Sunday afternoon daytime highs will bounce back up around +17 in some parts of Waikato.
The run of warmer than average afternoons looks set to continue until mid to late next week, then colder Sou’Westers return out of the Southern Ocean to end next week and likely go into next weekend with more unsettled weather.

Hi Phil and the Weatherwatch team, hey what do you guys make of this media blowup about this “rare” weather event – the Sudden Stratospheric Warming, happening in a town near you very soon!! Is the Antarctic going to rise up and kick our butts or is it hype or is there a real reason for concern!! Your thoughts please?
