The Situation
A ridge of high pressure gradually builds over the country today and Wednesday. Northerlies strengthen in the south late on Wednesday, ahead of a complex trough that affects the far south and West Coast on Thursday. The trough moves northeast and a low develops west of the West Coast late on Thursday. The low deepens and travels northeast on Friday, reaching the North Island on Saturday as a front makes landfall in the far south.
