This week we have another set up that may see isolated areas of heavy rain but also settled, frosty, weather for others.

In a nut shell a large low in the Tasman Sea today moves into central and northern NZ but gets guided more northwards for the rest of the week. This will leave NZ in the middle of an ‘air pressure sandwich’, with a belt of lows to the north and stronger/higher air pressure pushing into the south.

Winds between these two systems (easterly quarter) should also increase this week. While no storm is forecast the weather this week may produce isolated areas of severe weather, but generally speaking, the most settled weather should be in the lower half of the South Island.
