While the North Island is being affected by a system from the sub-tropics it’s winter as usual in the South Island with some incredibly low temperatures this morning.
It was -9 again in Omarama, in the McKenzie Basin, at 8am this morning while a number of other places were around the -1 mark.
Even as of 10am it was still just 2 degrees in Christchurch and just 1 in Queenstown. It was -4 in Omarama.
A ridge of high pressure remains over the South Island and should shield it from the sub-tropical storm in the north. Meanwhile a very weak front will brush up the east coast tonight. This weak front isn’t likely to deliver much precipitation however a few snow flurries are possible along coastal hills down to a couple hundred metres tonight or tomorrow night when temperatures drop.
