Weather experts are forecasting the first proper winter blast of 2022 may hit the country this weekend. Weather Watch.co.nz says a storm is forecast to develop this week in the Southern Ocean and by Friday or Saturday Antarctic southerlies could bring the first snow to sea level, or low level for the year.. WeatherWatch.co.nz now has snow icons appearing in places like Dunedin, Invercargill, Gore and Queenstown for Saturday. And MetService says a north-westerly flow will bring significant amounts of rain across many areas ahead of snowfalls expected by Friday. This is likely to be the first heavy snow of the season in these areas and snow may lower to levels where it can cause stress to livestock. There is a potential for warning amounts of snow above about 800 metres for the Canterbury high country south of the Rangitata River and for Otago west of about Alexandra on Friday and possibly severe north-westerly gales about the Marlborough Sounds, Wellington and Wairarapa.
