Thunderstorms and hail are more than a possibility over parts of the eastern South Island later today.
A front is expected to be brief but bring a very gusty southerly change, with a sharp drop in temperature and snow expected to lower again over Banks Peninsula.
This is a typical spring set up especially over the Canterbury Plains with daytime warming seeing the thermometer possibly nudge 20 degrees or a tad higher, before the change.
Weather analyst Richard Green believes that it shouldn’t last particularly long but could be a strong and squally event. “The winds should pick up quite dramatically from the south for a while and the temperature will certainly plummet”. Green also says “Christchurch should see the front move through close to dinner time but it could be all over by midnight”.
Sunny skies are set to prevail over Canterbury tomorrow before another southerly change is expected on Thursday.
