NZ's 5 day Rainfall and Snowfall maps

We're entering a new phase of weather, one that will bring rain to the western side of NZ, heavy snow on the Southern Alps and windy, warm and dry weather for many other parts of the country.

VIDEO: Surge of Windy Westerlies to dominate NZ next two weeks

New Zealand is in for a change with windier westerlies coming our way for the next two weeks at least.

This means more rain for western New Zealand and dry conditions in the east of both islands.

A big new westerly weather pattern is coming + 7 day rainfall

Monday kicks off wintry in the south and a bit cloudy in the west but this week we have a big change coming - a westerly flow.

NZ's entering a new weather pattern and it's FULL of westerlies (+3 Maps)

A significant change is coming to our weather pattern with at least 10 to 14 days of westerly winds dominating, not your normal mid-winter pattern. This more spring/autumn-like pattern means a variety of milder days and colder ones across the country with coldest air sticking to the south and warmest air sticking to the north.

Past 7 days rainfall Map + upcoming 5 day rainfall outlook Map

We had some better rainfall totals this past week for dry areas but the upcoming forecast swings back to dry or many. 

The pattern over the coming week is for more westerlies which will encourage rain on the West Coast, showers for the North Island's western side and mostly dry for eastern New Zealand.

The maps below show what has been and what is coming.

Another big high is parked to our west but it’s not so straightforward as the last one.

This next high will encourage cooler southerlies this weekend but the centre of the high will weaken before it reaches northern NZ - plus the high will track north of us, not directly over us.

Despite the rain, some parts of NZ may still have less than 5mm coming next 14 days (+2 Maps)

Rain has fallen across a large portion of New Zealand in recent days with northern regions getting a good downpour on Thursday to help dry places. A number of regions are below average rainfall-wise, some only have about one third of where they should be by mid-year.

VIDEO: Cooler change coming after warm, wet Thursday in the north

NZ is stuck between two big highs and as a result we have a band of rain with heavy falls slowly crossing over the North Island today.

Behind it is a cooler southerly which will drop temperatures across Friday and Saturday.

Rainfall forecast: Today plus next 3 day accumulations (+2 Maps)

We have one large high moving away and another large one moving in - wedged neatly between the two is an area of mild sub-tropical rain.

Totals vary today - a combination of high pressure weakening some rain bands, along with our mountains and ranges - while the sub-tropical energy is also helping fuel much heavier falls, especially at sea and brushing some parts of the North Island

Why's it so warm? It's all due to one large high pressure system that's now leaving (+3 Maps)

A cool down is coming but the warmer than normal sub-tropical air flow still covers the North Island for Thursday.
