Frosts are already developing in parts of the South Island’s interior as high pressure moves in over more of the country easing winds and bringing clearer skies.  The central North Island is also dropping down closer to zero, especially near the mountains.

With the high rolling in and winds and skies clearing, tonight will be cold for many.

Here’s how cold it will be around 6am on Friday:

The areas in dark blue are low single digits and below zero. Frosts are possible as far north as Waikato – however the warmer sub-tropical northerly flow is expected to kick in early Friday morning in the upper North Island (remember this is a short lived high – Thurs PM/Fri AM) – if this happens early enough it could remove the frost risk for many upper North Island and coastal areas. A fine line for many!
