The first work week of spring is sure starting off wet. A big blob of rain has been spreading over the North Island during the overnight. Even places that aren’t getting rain now, like Gisborne and Hawkes Bay, will eventually end up with rain, probably before midday.
The top of the South Island is also getting a bit wet this morning.
Tomorrow, most of us will see lingering chances for showers as a developing low off our east coast helps to keep things unsettled.
But on Wednesday, a large ridge of high pressure will slide in from the northwest. That will begin to dry out the North Island.
However, the currently forecasted position and shape of the high sets up a persistent onshore flow for the western regions of both islands.
That means that despite the influence of this high (or rather, because of it) the upper NI, including Auckland, will continue to see some shower chances on Wednesday. Although the chance will be greatly diminished from what will be seen today and tomorrow.
However, for the western regions of the South Island there will still be some pretty good chances for showers.
On Thursday, the southwest flow over upper North Island begins to turn a bit more westerly. That bring the showers chances there to an end.
On the Mainland, however, that persistent flow will continue to shower chances going for the western regions. Even some heavy rain will be possible about the West Coast late on Thursday into Friday.
Friday will likely be another dry day for much of the North Island, although the lower sections could start to see some showers as another spring front starts to develop and advance on the country.
That same front will bring yet another wet day to the western Mainland as we wrap up the first work-week of Spring.

Some forecasts are predicting very strong Westerly winds towards end of the week for the North Island. Plus showers. Would you agree, chances of becoming fine? Thank you.

Another one of those “once in 50 yr” rain makers that we now seem to get every few weeks passed over again during the night and morning leaving a ton of water all over the place. So another clean up to do once it is dry enough, and as for mowing the grass, well, maybe sometime if it ever drys out enough. Am over all this rain and soggy muddy section, bring on some good sunny dry weather.
Any ideas on if this could happen anytime soon.
