Southerly winds for Wellington Anniversary Weekend

Here’s the latest Press Release from MetService:

The MetService weather forecast for Wellington’s long weekend is for more of the same, with periods of southerly wind and passing showers.

“The last dry weekend in Wellington was in mid-November last year”, commented MetService Weather Ambassador, Bob McDavitt. “So it is no great surprise that showery southerlies are likely again during the coming Anniversary weekend”.

Mr. McDavitt added that the showers and southerly winds are not expected to be as intense as last weekend, and should not require any weather warnings. “There is a complex trough affecting the North Island for the next few days, and it seems set to deliver one period of southerlies to the region on Friday lasting through Saturday, and another late on Sunday or early on Monday”.

“Wellington’s anniversary holiday is celebrated on Monday by people living in a large part of the south half of the North Island. If you are in this area and looking for some sunny mild weather with light winds this weekend to plan an anniversary BBQ or have some outdoor fun then your best bet is Sunday during the day”.

Strange looking weather map

If you’ve looked at this weekend’s forecast weather map you might notice something strange. Something we haven’t seen for quite some time – over a month in fact. Here’s a sneak peek at the situation for noon Saturday,

Yes folks, do not be alarmed, that “H” with a big number next to it is a good thing! Finally, we have an anticyclone crossing the country. So noteworthy is this event, that MetService have issued a press release

AUGUST ENDS ON A HIGH

MetService forecasters expect the last few days of August to bring generally dry weather as an anticyclone moves across the South Island.

“This is the first anticyclone to visit New Zealand since mid-July’, said MetService Weather Ambassador, Bob McDavitt. “It will bring light winds to much of the country and several dry days to the east of the South Island and southern parts of the North Island, where they are most needed”.

The anticyclone is not 100% dry. As pressures rise over the South Island on Friday, a southwesterly wind change is likely to bring a brief period of showers to eastern districts. Over the weekend, easterly winds may bring cloud and showers to Coromandel and Northland, and drizzle is likely for parts of the West Coast of the South Island.

“It’ll should be a good weekend for skiing”, added Mr. McDavitt.

So, stock up the sun cream, get the kids pumped for sport and pack the picnic basket! Enjoy it while it lasts.

Sadly, I’m working all weekend… weather forecasting! Bugger.

Now that’s a weather warning!

They don’t come much bigger than this…

Hello Winter!

You know winter has gripped the country when the MetService Warning Map look like this,

That was the warning status at midday today (Saturday 5 July), and if you could see the original animated map, you’d note that most of those little snow icons in the east of both islands were flashing between snow and strong winds. Needless to say the current Severe Weather Warning is extensive and covers many regions of the country.

There has already been significant snow falls in the lower South Island and as I type this early afternoon, snow is spreading up through Canterbury and is now falling in Christchurch (thanks for the report Nic!). Even here in Wellington we had some sleet and light snow showers on the hills earlier today – a stark contrast to the now clear skies. Don’t be fooled by the current lull in the capital though, the real nasty weather should arrive this evening – just in time for kickoff at the stadium…

Wrap up warm – this outbreak is a cold one!

UPDATE – Sun 6 July – Looks like I won’t be recommending the “AA Roadwatch” website anymore… When icy conditions and widespread snow affect many roads the last thing you want to see on a public road info page is,

As a result of the current conditions we are experiencing high demand for this service.

Followed by a blank page where road info should be!

A big thumbs down to the AA – this coming from a dedicated member for 17 years. If you can’t keep your website up and running when the public need it most, you might as well pull the plug.  Shame on you AA.

MetService Webcam

For those of you curious about the current weather in Wellington (and the view from my workplace), MetService now provide a live webcam with current temperature and wind conditions,

The webcam pans left and right between north and south, through east, with imagery streaming live via a windows media video feed. (Before viewing the video stream you may be asked to install a plugin or codec for your browser.) The temperature and wind data come from a weather station at MetService in Kelburn.

This is a nice (albeit long overdue!) addition to the website. Check it out via the Wellington weather page, or directly via this link.
