A sou’ west change is expected to move up the South Island today which could generate showery activity but also the chance of thunderstorms rolling over parts of the south.

It’s still a marginal call if these thunderstorms will trigger off but if they do develop they could move up along the West Coast with a chance of hail and eastern parts of Otago and Southland may hear a rumble or two.
Canterbury could also see some thundery events as there appears to be a little daytime heating before the sou’ wester truly kicks in.

Rain moved in last night over many parts of the North Island but as quickly as it settled in it’s likely to disappear from many places this morning if it hasn’t already and then to reveal largely blue skies with just a few cloudy patches in some cases.

Temperatures in the south are likely to be cool compared to parts of Canterbury and Otago yesterday with Timaru just falling short of 30 degrees.West Coasters are likely to see the coolest weather conditions across the Mainalnd today.

One week from now and Daylight Saving would have ended for the summer season and clocks would have gone back one hour and will move forward once again in September.
