CHILLY WEEK AHEAD: Cantabrians might get their first snowfall of the year next week.

Forecasters are keeping a wary eye on a possible cold snap that could bring snow down to sea level in Canterbury early next week.

Computer models for the past few days have been picking that a blast of bitter, sub-Antarctic air will work its way up the South Island on Monday.

The coldest air looks likely to be over Christchurch about dawn on Tuesday.

Blue Skies Weather forecaster Tony Trewinnard said the air was "cold enough for snow to fall to sea level".

What was not clear was how much moisture the air mass would contain to make snow.

"The question is, how much snow will form higher up to start falling?" he said.

Mild west to northwesterly weather is forecast over the weekend.
