New Zealand finds itself caught between two areas of high pressure for the next few days. One to the southwest, the other to the northeast. This leaves us saddled with a complex low pressure system which has nowhere else to go.

There’s a lot of events happening this weekend – how could they be affected by this situation?

A low is once again sitting to the northwest of New Zealand, keeping the air moist and ripe for periods of rain or drizzle over the North Island and upper South Island tomorrow. The low is expected to continue to sit tight in the Tasman sea slowly flicking rain bands over the those areas exposed to the north to northeast. On Tuesday the low is predicted...

Here's a time lapse video shot from Metservice HQ in Wellington today.There's plenty to see with a shallow unstable layer breaking up for a while as it flows into the harbour basin, to reveal lenticular waves in the stable westerlies aloft. Also, ferries! ^RK

An approaching low is forecast to become slow moving west of the North Island, dragging several bands of moisture over the country, but no region is likely to see rain all weekend.

It’s looking drier on Saturday over the upper North Island than previously...

With the flow from the northeast, the wettest places look to be around the central and upper North...

What is Virga?

This great shot from susan scrimshaw @scrimcsue appears to show rain falling from the sky over Wainuiomata hill last night near Wellington. Nothing was picked up in the rain gauges, and it is likely that this rain evaporated before it hit the ground. This is called virga, and is a relatively common occurrence. See this blog post for another example looking like 'a row of...

Following today's weak front, which brought with it a few light showers and cooler southerly winds, a new ridge of high pressure builds over the country. A sunny autumn Sunday is forecast for most places, with those cooler southerly winds dying away.
