Enormous low pressure system engulfs NZ, final cold change then it all clears

As exclusively forecast a week ago a number of big lows have merged to create one enormous belt of low pressure which has covered the entire New Zealand area.

Now a storm in the Southern Ocean is helping send off this big low with one final act – an Antarctic southerly for some places. 

Wednesday will have single digit highs in a number of southern regions and if you do make it to double digits there’s a good chance the feels like temperature (wind chill) will make it feel colder. The upper North Island is least affected by the colder change but some in the lower North Island will feel it, Wellington may only just reach 10 degrees. says one positive for newborn livestock is that this final southerly change looks fairly dry, so snow may fall to low levels briefly but won’t amount to much. It’s dampness plus windchill that is the biggest killer for newborn livestock. Wednesday, while cold, will be fairly dry with showers and snow flurries clearing. Warmer air and higher pressure returns on Thursday.
