After a wild few days of weather that saw thousands of lightning strikes and torrential rain across the country today will offer some respite.

MetService meteorologist Karl Loots said overnight the weather had been in a bit of a "lull".

"After yesterday there has been nothing too spectacular. The South Island's West Coast and parts of Otago have had some rain and the odd thunderstorm, and this rain should spread into parts of Canterbury this morning."

Today a strong west to southwest flow would cover the country.

Auckland would see some showers becoming isolated in the morning with sunny spells increasing and a high of 20C. Similar weather was forecast for much of the upper North Island.

The main action today would be on the South Island's West Coast, where a couple of heavy rain warnings were in force.

There was also a high risk of thunderstorms in Westland, Buller, western Nelson, and the Southern Alps. These storms could be accompanied by heavy rain up to 25mm/h, strong wind gusts to 100 km/h and the chance of a small coastal tornado.

A strong unstable northwesterly flow would also affect the lower North Island with a moderate risk of thunderstorms in Horowhenua Kāpiti Coast and about the inland ranges. These storms could be accompanied by wind gusts up to 110 km/h and heavy rain at 20mm/h.

Tomorrow another front would arrive bringing rain into the far south. It would become slow-moving and gradually make its way on to the North Island with potential for rain in Wellington and showers in western and northern areas.

On Friday the showers would gradually clear as a ridge of high pressure began to build in the South Island making its way north through the day.

This was good news for the weekend, with most of the country in for a much-needed dose of fine weather.

The only weather to watch out for was a weak front in the far south in the early hours of Saturday morning, and another on Sunday bringing some heavy rain also in the far south.
