On Friday we have a strong northwesterly airflow over NZ, while a front moves over the South Island during the morning and afternoon.
The front then moves onto the lower North Island later in the day or overnight, weakening as it goes.
That moment when the fog rolls in on a beautiful sunny afternoon - not something that happens too often, but it's always humid when it does!

Updated --- As WeatherWatch.co.nz forecast this morning the mercury has hit 30 degrees in eastern parts of both islands. As of 2:30pm it was officially 30 degrees in Hastings and Napier, 29 degrees in Ashburton and 27 degrees in Dunedin. Private weather stations right across Canterbury and Hawkes Bay are now at 30 degrees or even slightly higher.
We've seen warm weather dominate the country through the middle of this week - with very high temperatures in parts of the eastern South Island especially!
Looking ahead to the weekend, we have rain or showers on the western side of the North Island spreading further north, though in the places that need it the most - the South Island - it's not looking as hopeful.
Finding it a bit hot and muggy? You're not alone. For the next 24 to 48 hours New Zealand is under a stream of humid and subtropical air spilling southwards over us.
Strong, gusty crosswinds caused problems this week at Cork Airport in Ireland.
The pilot of a CityJet flight from London City Airport was forced to abort his landing after touchdown, and perform a 'go around' procedure.
The plane landed safely a few minutes later - but not before a few panicky moments!

Thursday looks fairly consistent around much of the country, though of course, as always in late spring, there are some exceptions to the rule!
In the afternoon, and into evening, there may be a heavy isolated shower or two right the way from Northland down to the Waikato.
On Thursday, the same northwest airflow which has brought vastly different conditions to the east and west of the country is staying put.
Basically this results in sunny and hot weather in the east, while there's cloudier skies in the west with showers.
Another burst of spring wind and rain is coming in – with hot, mostly, dry weather in the east of both islands and daytime highs reaching around 30 degrees for some.
Heavy rain is likely on the West Coast with some spillover into the dry east.
