The topsy turvy week rolls on and although the skies clear today over much of the North Island after yesterdays inclement spell, mainlanders are gearing up for another wintry change.

The next front is expected to slowly move northward over the South Island today and it should reach Christchurch early this evening. Ahead of the front, mildish northerlies will see the mercury peak in the high teens, if not the 20 degree mark in parts of Marlborough and Canterbury.

As the winds swing from north to south, heavy showers are contained in this southerly change with rain, hail, sleet and even snow to low levels expected in the south and east. Thunderstorms and strong and gusty winds aren’t out of the picture necessarily either. Both coastlines should see the beefy wintry mix at some stage today or tonight.

This mass of cold air is expected to be felt across much of the North Island tomorrow.
