NZHerald.co.nz and WeatherWatch.co.nz bring you the latest information with an extended weather forecast presented by Philip Duncan.

This video covers the latest squalls and thunderstorms (tracking around central NZ as of mid afternoon and heading northwards for tonight).

We then focus on the South Island – in particular Southland.  Phil mentions that a snow warning is possible for Southland – well just a couple hours after this video was recorded a snow warning was issued!  See below for the snow warning as of 2pm (please note, this page will not be updated – and therefore the warning on this page won’t be updated either).

On the west coast (from Hokitika to Northland) more squally showers with hail, isolated thunder and localised damaging gales are expected on Thursday then should ease slowly on Friday.

We touch on the risk of snow for Canterbury – (see our story on the homepage for more details if you can’t view our video).

And finally we look at next week – a large high moving in…but did someone just say a potential sub-tropical low?  Some of the models are picking that for late Tuesday and Wednesday…but it’s only early days.  We’ll update you further on this possible sub-tropical low on Thursday afternoon here at WeatherWatch.co.nz.
