Sleet, snow forecast
LATEST: Cantabrians should be prepared for some "unpleasant" weather conditions this week.
A MetService spokesman said a cold air flow could bring snow to 200 metres above sea level in Canterbury late on Tuesday. However, sleet could be down to sea level.
He said while the snow would not cause too many problems, it was accompanied by strong southerly winds, which would have a freezing wind chill factor, which would make it unpleasant to be outside.
However, it should clear overnight.
He predicted frosts on Wednesday night.
Blues Skies Weather and Climate Services are warning that a "very cold bubble" of sub-Antarctic air will blow rapidly over the region late on Tuesday causing showers in the afternoon and snow flurries down to 200 metres above sea level that night.
A few centimetres of snow is expected down to 200m by early Wednesday morning, and about three to five centimetres is expected above 400m.
The falls will be mostly about Banks Peninsula and the coastal hills of North and South Canterbury.
