A special weather advisory was issued yesterday warning of a cold southerly change, which was expected to spread north over the South Island this afternoon and evening.
Snow was predicted to 200m-300m from this evening but snow accumulations were not expected to reach warning amounts, MetService said.
The change in weather was predicted to bring rain, with snow about the hills, this evening in Dunedin, and rain and snow showers in Queenstown.
A southwesterly change was then expected to hit, dropping temperatures to single figures tomorrow.
