It proved rather less than accurate last week.
As did metservice.
However a quick look at this mornings RASP indicates a large convergence from the Waikato all the way down pass Mt Ruapehu.
7-9000ft cloud bases and 7 knot climbs.
Very little over-development.
A converging sea breeze from the west coast colliding with the light S to Se winds.
We will see.
