Thursday September 23

Ruapehu: Strong northerlies turning northeasterly through the late afternoon then easing later in the evening. Some significant precipitation forecast with a mixture of snow and rain expected. Totals 7-20+cm possible but amongst rain it is hard to pick.

Extended Forecast

Relatively mild weather for the next few days around the south is expected to change with snow arriving over the weekend. Some big numbers are possible for Saturday with falls maybe starting late on Friday. There is some disagreement in the models about just how much may fall but there does look to be something in it, giving a boost to spring conditions around the Southern Lakes and some parts of Canterbury.

Up North a persistent pattern of rain should clear on Saturday with some sun before more precipitation arrives Sunday with a what looks like a good chance of snow on Monday.

Overall, winter is still alive, take care, get out and make the most of it.
