South Islanders - don't be fooled by milder temperatures, MetService forecasters are saying there's a cold snap on its way.
The front is expected to move northwards over the South Island tomorrow, followed by an outbreak of cold air.
MetService says temperatures are likely to be ''significantly colder'' than they have been during the last few weeks, in the east from Southland to Marlborough.
Rain is expected to turn to snow in higher parts of North Canterbury and Marlborough overnight tomorrow. Snow may fall above 500 metres in these areas on Tuesday, with cold rain at lower levels.
''There is also the possibility of significant snow accumulations about the foothills of Mid Canterbury, but this is a lower risk than further north.''
MetService is warning farmers in these areas to be aware of the risk to vulnerable stock. The cold, wet conditions may persist through much of Wednesday.
Early fog delays flights
A foggy start to the day in Christchurch has delayed flights at Christchurch airport.
Although skies have cleared, the early morning conditions disrupted domestic and international flights.
MetService forecast that the low cloud and fog would clear, making way for a fine day with northwesterly winds and a high of 22 degrees.
