High lingers for another 36 hours

A large anticyclone that has dominated our weather all week should remain over the country for at least the next day or so predicts

The high, which has brought very little wind and mostly dry and sunny weather has been over the country since last weekend.

However a broad area of low pressure is moving in from the Tasman Sea as the high slowly moves away to the east.

The high should hold over the country for the rest of today and cling on to most of the North Island until the end of Friday.

The low that’s coming in is what we call shallow – which means the air pressure won’t be dropping much as it crosses New Zealand.  The high has a central air pressure of around 1020hPa and the low has a central air pressure of about 1005hPa.  This is a very small difference which explains why winds will remain light for the next 48 hours in most places and why the low isn’t expected to bring major rain.
