New Zealand looks set to be dominated by another ridge of high pressure which will bring settled conditions, cool nights and light winds to most.

However, a weak low sitting over the upper North Island means those from Northland to Coromandel Peninsula can expect cloud and showers tomorrow and on Tuesday. MetService also reports there is a low risk of isolated thunderstorms among the cloud and showers.

A few early morning thunderstorms developed today close to western coasts of Northland and Auckland, as well as a period of rain, due to an area of low pressure.

Last week a broad ridge of high pressure influenced weather for most of the week, which saw several cold nights and frosts over much of New Zealand.


MetService meteorologist Andy Best said the ridge moved away to the east on Thursday and was followed by a low-pressure system.

"A complex trough of low pressure over the Tasman Sea moved onto the country late Thursday, bringing rain in a strengthening, humid northeast flow," he said.

"During Thursday, 24hr rainfall totals ranged between 15mm and 30mm on the Westland Buller coasts but between 40 and 50mm in the ranges of the Tasman District as a front passed over the regions."

Elsewhere, the South Island will see mainly settled weather tomorrow but overall temperatures should be on the cooler side, WeatherWatch reports.

The upper South Island will see a few morning showers but will clear up for a mostly sunny, mainly fine day.

"A fairly cool day ahead for most of the country, temperatures just getting into the mid-teens for Auckland and Northland," WeatherWatch said.

"A mix of sun and cloud about the rest of Canterbury. Sunny for South Westland and Fiordland after any early cloud clears.

"Southland and Otago have a mostly cloudy day with showers at times, drying out from afternoon with sun breaking through for inland areas."
