The cool south west flow across New Zealand will continue today bringing another surge of showers and cold air into the Deep South then heading northwards.
On Monday the southerly change sparked thunderstorms over Christchurch before dropping hail on Wellington yesterday morning.
Today another cold front will race up the South Island reaching Wellington tonight/overnight. Again it comes with the risk of isolated hail but nothing widespread.
The front itself is fairly small.
As it moves up the South Island the Southern Alps will help fracture the front with two sets of showers moving up the western and eastern coastlines.
Temperatures will remain below average to average for most main centres.
As for Thursday conditions will improve with showers easing or clearing and cool sou’west winds also easing for most. The Deep South of the country will also see an improvement through Thursday and into Friday ahead of a large but short lived high moving in from Australia.
