Time for cool change in south

Southerners should dig out their winter woollies for a cold snap predicted to hit parts of Southland and Otago tomorrow night.

MetService meteorologist Dan Corbett said a short, sharp wintry blast would bring showers, southerly winds and snow to 400 metres.

Southland and Otago had experienced relatively mild weather since July but it was time to dig out those extra layers of clothing, he said. "Wednesday evening will be quite a shock compared to what we've had."

Temperatures are forecast to drop to 3 degrees Celsius in Invercargill, -1C in Queenstown and 2C in Alexandra and Gore tomorrow night.

The showers would ease on Friday but frosts would hit the region over the weekend, Mr Corbett said.
