High pressure dominates NZ, chokes rain band & converts it to downpours (+3 Maps)

High pressure continues to expand over NZ while a weak front stalls and falls apart over central NZ. The high pressure zone will smother the front – seeing it disintegrate and leaving behind some downpours around the North Island by Thursday afternoon.


Let’s get into the forecast for Wednesday to start with…

RAIN:
Most places are dry today but a front that has basically died over the lower North Island may still produce some showers around the lower North Island and upper South Island – track on rain radar today to get a better sense of it. But dry for most places under high pressure.

WIND:
That high also keeps winds light in most places.

TEMPERATURES:
Today is mild to milder than normal for the first week of November with temperatures into the mid 20s through both main islands.


WEEK & WEEKEND AHEAD
On Thursday high pressure departs to the east. The leftovers of that dead front will come back to life on Thursday in the form of inland afternoon downpours or thunderstorms for parts of the North Island. A few lighter showers are possible for the South Island’s west.

Windy nor’westers return over the South Island and lower North Island as the high pressure moves away to our east on Thursday and Friday, with those nor’westers producing higher temperatures in the eastern North Island and the upper South Island, north of Banks Peninsula basically. Heavy rain sets into the southern half of the West Coast on Friday.

By Saturday – Windy westerlies carry on with potentially severe gales through the upper South Island and along the Southern Alps – with heavy West Coast rain (watch for rain warnings) and further colder showers in Southland but a warm and windy nor-wester for much of the North Island.

Sunday sees conditions easing again – ahead of Monday’s next surge of spring weather in the form of a fairly weak cold front spreading into the lower North Island for a time.
