Northerlies will spread across much of NZ today with some regions enjoying sub-tropical connections, lifting temperatures above normal. For others it will be cloudy with a cool breeze, but overnight lows will be milder as the northerly airflow moves through.
Sunday is dry (or mostly dry) nationwide, but a rain band moves across New Zealand on Monday with westerlies moving in behind that for many.
COLDER SOUTH, WARMER NORTH:
Southland and coastal Otago will have cold airflows throughout the next day or two as a wintry southerly flow moves in (localised winds may be from varying directions through, like easterlies in some areas). Dunedin might not reach the teens today and on Monday single digit maximum temperatures are expected.
At the other end of NZ it’s quite the opposite. Parts of Northland, like Whangarei, wake up to around 9 degrees this morning but overnight tonight it’s double that number at 18 degrees due to sub tropical northerlies.
