Here’s what is making the weather headlines today…

AFTERNOON INSTABILITY / THUNDERSTORMS

Cold upper air produces unstable conditions for the North Island today and upper South Island, with the addition of higher surface moisture for the North Island storms there may produce heavier downpours and be more intense overall.

MIST OR FOG THIS MORNING

As we start to head into autumn fog will become a more frequent sight, settled conditions and clear skies can often lead to it’s development and this morning has this possibility.

The map below shows where fog is possible, fog may develop again overnight but this time more restricted to the South Island.

HIGH PRESSURE TO HANG AROUND THIS WEEK

Most of the week ahead has high pressure hanging around over New Zealand, this means overall the weather is going to be fairly settled. It’s not that straight forward though and usually never is.

Instability today as mentioned above will likely bring thunderstorms to the North Island and perhaps upper South Island. Showers or some rain for the eastern North Island on Tuesday eases later in the day. Wednesday is dry for most however a front moves into the far south bringing rain to Fiordland and a few spits further eastwards.

Thursday sees the chance of a few afternoon isolated showers about the lower South Island, mainly inland. On Friday cloud thickens up the east coast of the South Island and a few showers push in. Saturday is when conditions change, a strengthening southerly airflow brings rain or showers to the eastern South Island and a drop in temperatures, afternoon thunderstorms possible for some North Island regions.
