Heavy snow and wintry cold rain carries on for the eastern South Island and is moving into the lower North Island and eastern North Island over the next two days – before easing as high pressure grows. The high pressure zone that is moving in will dry the South Island skies out by Thursday bringing heavy frosts, becoming severe into the weekend.

This may bring further black ice, and cause pipe/plumbing issues for some with temperatures expected to go below -5C and -7C (or lower) through the interior of the South Island.

But the North Island has a lower risk of frost this week due to more wind, cloud and rain or snow blowing through. Snow might impact the Desert Road later on Wednesday or on Thursday. We have your updated forecast through to Sunday.
