Today's situationThursday 19th September, 2019
High pressure increases further today bringing light winds to most, if not all, regions. It is a dry day too for the most part but a few light showers will clip the very top half of Northland and also Fiordland and maybe coastal Southland. A mild day but a cool night ahead.
14 day outlook
High pressure is now dominating NZ and will be over the South Island until Sunday and the North Island until Monday. We'll see cloudy areas along the western side of the North Island today but on Friday that shifts more to the east. The centre of this powerful high (air pressure around 1040hPa) will drift over NZ this weekend - mostly focused over the North Island by Sunday which will allow a Sub-Tropical airflow down over the South Island (plus it's a nor'wester - so it should be mild in the east and south!). By Monday the high lingers over the North Island with warm sub-tropical winds - but a cold front next Tuesday brings rain and a SW change. Another high possible by next Friday.
We are seeing some areas starting to dry out a little now and the long range forecast suggests many regions may dry out further before rain arrives. Mostly dry weather dominates NZ (except the West Coast) for the next several days but coupled with high pressure and mild days (especially mild later this weekend early next week) we should get fantastic nationwide pasture growth. The downside? The ground will dry out fairly quickly over the rest of this month.
