This will push the instability slightly further east along the inland plain fringes Monday evening, as its inland heating and mild upper air it will only be small hail but high rainfall rates.
Mid week looks good for canterbury and christchurch for a classic thunder/hail set up, upper air is much colder around -28c on the 500mb so heres hoping.
Tuesday afternoon/evening could see an isolated cell or two skirt up the coast to banks penninsula as well.
So interesting times weve had one proper storm chase so far, and im hoping for many more to come.
As John would say for a Fruitful thunderstorm season
