General May Weather

[drew]

Pretty ugly in the Naki this morning. Lots of wind, rain, hail and THUNDER!!

We have lost all tv channels (no cartoons for the kids) so I imagine the repeater up the mountain has taken a beating.

Corelated lighting shows plenty of strikes locally!



Wind has eased just now.

[CHCH Weather Chaser]

The opposite has happened here in CHCH. In the last 15 minutes the wind has really picked up, gusting to or near gale at times now. Clear blue sky to the east and dirty looking cloud to the west. Brief, very brief rain hit last night, looks like North Canterbury getting a brief spell of what shows up as rather heavy on the radar.

Do we need to have another discussion on wind names, etc?...Beaufort scale here:
http://en.wikipedia.org/wiki/Beaufort_scale



Maximum gust at Jeff's station (which you are so oft to quote as conditions in CHCH...) only show a max gust of 38 km/h...and on the Beaufort, that's a 'strong breeze'...hardly a 'near gale' (50-61 km/h)

I was actually referring to City weather station. CCC one. Even although thats sometimes dodgy it was showing 67km/h NW earlier on. Anyways in Wellington very stormy this morning according to the radio.

I see Le Bons Bay, on Banks Peninsula reported NW mean-winds of 76 km/h at 6am - down to 57 km/h at 9am. Winds still up around 72 km/hr on the Port Hills (Sugarloaf) though.

And yes, at 4am Wgtn Aero reported N'erly winds of at least 74 km/h, gusting to 117 km/h - eased somewhat now.

Got a bit of a hammering early in the morning with some pretty big gusts of wind and caused the power to go off as a pine tree had fallen on to some power lines just down the road. I stayed up all through the early hours of the morning watching all the action. Around 5am there were some brief heavy falls with some frequent lightning flashes I saw at lest 20 flashes after that it all eased off as the front had passed.

[Manukau heads obs]

at first I thought we were going to miss the main rain bands, but a big lot developed as it moved onto us
14mm here from that
temperature has dropped from 17C to 13.5C now

big change in average temperature over the last few days compared to a week ago...5C difference!

[David]

That was a surprisingly weak front, broke into little pieces as it moved onto land....just 0.3mm rain...at least its warm, 17° here after peaking at 21° earlier

[Vertigo]

once again, brian, you were in the right spot. auckland seems to often create a rain void during events like this, we got very little.

[jamie]

18.4mm in horshamdowns from that front.. was heavy rain for a lot of the afternoon.

Thanks for the reports guys. These threads seem to have become a bit tangled, but those reports tie in quite nicely. Shame MetVUW don't archive the New Plymouth radar images, but in the Wgtn 6am radar image (same time as reported tornado) you can just see the front about to scrape Opunake.

[Tornado Tim]

Waikato residents may very well expect a frost tonight, DPs are plummeting.
If the sky is clear, then we may very well get 1.

[David]

Down to 2.4°C here this morning...brrr

[Manukau heads obs]

going to end up being the coldest and wettest may in a long time here

[Tornado Tim]

Frost here 0.5°C Recorded here with a -1°C DP.

[TokWW]

Overnight lows of -1.3ºC -1.5ºC and -3.5ºC for the 3 Tokoroa stations on the net. A clear sky and very light SSE winds.

[Tornado Tim]

Not too sure about Auckland but the Waikato is getting 1 of those very low DP days again.
Id say another frost on the cards if skies stay clear, and wind slows down.

[David]

Shallow CB passing to the south of Auckland with beautiful structure and what looks to be a very-well defined hail core. Here's some pics Any thoughts?

[Manukau heads obs]

could see that from here
looked like a snow cloud to me!!

[Tornado Tim]

Could be sleet, if the temp was low enough.....
DP is 2.4°C here....

[Manukau heads obs]

yesterday must be one of the coldest days for May for a long time for auckland
I see Ricky only averaged 7.8C for the 24 hours to 9am!

[David]

That site is one of the many sites not working for me this afternoon. Metservice, metvuw and this forum and a few other sites I've tried work but for the last hour or so most of the internet is down

Looks like another cold night tonight, low humidity and temperature and mainly clear out there.

[Manukau heads obs]

good frosts inland I would say 2 nite
as the wind is dropping right away here on the west coast, and its only 8.5C now
the 24 hours to 9am tomorrow morning are going to be even colder
heading for the coldest may for many years

[David]

as the wind is dropping right away here on the west coast, and its only 8.5C now

I've always wondered why the temperature falls away so quickly in the evening in your area, 9.6° and falling steadily here but on clearer nights your overall low is a little higher than a lot of other areas (even Grey Lynn last night). If it stays clear all night I would expect 2° here again tomorrow morning

[Manukau heads obs]

we were alot warmer here last night than because the wind did not drop..but it has 2 nite
