Sunny weather won't grace Northland until later this week as an approaching low is forecast to bring more showers heading into the weekend.

An easterly flow means a few showers tomorrow and Thursday, especially on the east coast, before a low pressure system approaches from the Tasman Sea.

MetService meteorologist Claire Flynn said although the low would not come near Northland, its impact would result in scattered showers for most of the week.

Last weekends' rain was caused by a moist northeasterly flow which brought humid air from the tropics that dumped nearly a month's worth of rain in two days over parts of the region.


This air was then pushed away by a cool southerly change, she said.

Ms Flynn said temperatures in many places around the country, including Northland, were currently below normal for January, due to the southerly flow.

As the ridge builds over the country, she said temperatures should gradually return to normal during the week.

"At the moment, there's not much wind in Northland but an easterly flow developing tomorrow (today) will push showers inland," she said.

Whangarei was among the hottest places in the country mid-afternoon yesterday with a temperature of 27.9C.
