Incoming cold snap, Temps to tumble even further

The cold change predicted to arrive on Sunday looks set to knock temperatures down even further as air from near Antarctica is yet again dredged up northwards. says the wintry snap this weekend isn’t at the major even of the scale, but severe weather is expected in the form of wind chill, gales and heavy snow for some areas above 200m.

“There is a chance we may see some snow going to low levels around Dunedin on Sunday” says weather analyst Aaron Wilkinson.  “Dunedin has a high of just six on Sunday with wintry showers to sea level and a few snow flurries possible for the higher suburbs”. 

Mr Wilkinson says hail and wintry showers will then push into Christchurch.  “The high for Christchurch on Sunday is seven degrees with hail, sleet possible and some snow to low levels around the city.  But long dry spells can also be expected”.

Head weather analyst Philip Duncan says the cold air is the main feature, with the forecast not calling for a lot of precipitation.  “This isn’t a major system, it’s fairly short and sharp – bringing only 24 to 36 hours of wintry weather before a high moves in from the Tasman”.

Mr Duncan says farmers should be prepared for heavier snow falls in the ranges of both islands, with snow also falling above 400m in the lower North Island by late Sunday as a gale southerly arrives.

“The wind chill will be signfiicant for some centres and farms, dropping well below zero for some expoxsed areas which will cause stress on stock”.

Snow may again close the Desert Road on Sunday night and Monday – but for the most part snow shouldn’t cause too many major headaches predicts WeatherWatch.

Hi,do you have any estimates of the amounts and level of snow likely for south Canterbury this sun Mon?;

Hi there

You could get 3 to 5cm down to 300 / 200m. Models are currently suggesting sea level snow is possible with 1 to 3cm falling to this level. Weather forecasts on the main page (re Chch and Dunedin) will be updated accordingly this afternoon with the latest information.

Hi there,

What would be your call at this stage for snow levels around the central Plateau, (rural Taupo area) over Sunday/Monday ? We farm at around the 400-500 metre mark, looks like it might be cold enough Sunday night/early Monday morning, but perhaps not enough moisture around our region for snowfall ?

Cheers !

Hi there

Pretty much what your saying is about right. South of Lake Taupo snowfall amounts will be slightly higher. Where you are, you may only get a few flurries passing through about the times you mention.

There seems to be 2011’s pattern of a 2-3 week cycle of polar blasts coming through. Is this the last of it or are we going to see more of this through Aug/Sep?

If I could see that far into the future I’d possible be earning more money! But the longest range weather models we have at the moment indicate perhaps there could be something between the 22nd and 24th July but maybe not as cold.

Chances are there could be a few more cold snaps come through at the very least this winter. Will just have to wait and see!
