A southerly change then a more settled spell

September 17, 2012

The week will start off with an active trough and a southerly change moving up the country but more settled weather will arrive by midweek.

Media and Communications Meteorologist Daniel Corbett commented “There will be a noticeable southerly change with some active thunderstorms, followed by colder temperatures and a lowering snow level”.

The cold southerly behind the active front will bring a notable drop in temperature along with brief snow falls down to several hundred metres for parts of Fiordland up to Canterbury, and briefly about the top of the Desert Road around dawn on Tuesday. MetService have issued a Special Weather Advisory to highlight this brief wintry spell.

A large anticyclone will then build in behind the departing trough during Tuesday to bring more settled weather for much of the remainder of the week. The anticyclone will bring the typical risk of some overnight frosts and perhaps some mist and fog patches at times.
