Sat pic shows a lot of thundery Cb cloud in the Tasman with the Trough.

Temperature warmed up here overnight from 11C yesterday evening to 15C this morning with the rising dewpoints, dewpoints currently 15C, humid for the time of year.

And Castle Rock, Coromandel has received 181mm since 12am 9th June, with 112mm falling in the 8 hours from midnight last night!

[jamie]

when is this trough meant to come through?

[Dale]

Right about... now.

Suns out, heavy rainfall overnight has cleared and the low cloud streaming in hugging the bombays enough to put them out of sight from home.. you can almost reach up and pull the base down further.

None of those wind gusts are strong enough for warnings, and I don't think they issue warnings if it's only for a small area.

More on the Dunedin gales- I really would have though a gale uprooting trees and damaging buildings in a main centre might have warrented warning status? Unless of course it was worse than predicted.

[Manukau heads obs]

is it also that the NE wind funnels down the harbour and right into the city?

[Nev]

Have to say that's one of the better weather stories I've read -

I've never seen wind warnings issued for gusts below 120km/h. By all accounts, the highest gust was 109km/h and that was on swampy summit, which is pretty high and where no one lives.
If we want criteria for wind warnings changed, I suppose we would have to tell the government.

The MS forecast early morning fog for Thurs/Fri this week for Christchurch, but they also say strong NE winds and easing on Friday.
Doesnt make sense to me as you wont see Fog if there is strong winds blowing, as it will just break it all up.

If it's sea fog that may not always be the case. You might also have the surface inversion forming and cutting off the strong winds from below, hence it would be calm and foggy and low levels.
When I see fog forecast (not that is happens often in Wellington) I don't question it too much, nor complain if it's wrong, simply because fog must be the hardest thing to forecast accurately. I don't think anyone ever can or ever will get it right everytime.

Further to what Myself said, the article also states that...

...and wind in Dunedin city gusted up to 67km. The winds were not particularly strong, but were coming from an unusual direction, so caused more damage than winds of that speed might otherwise do, a MetService forecaster said.

I have to agree with....Myself...(wierd typing that!) I lived in Monterey, California, about a 2 hour drive south of San Fransisco and we would quite often get good wind with the sea fog that would retreat in the morning and move in at night...around those parts they are, actually, pretty good about forecasting it and it was always pretty impressive when it moved in! most likely because it is something that happens ALL THE TIME

nice looking line of CB's way out to the east of here
(not sure which thread I should be posting in for current weather?)

[Lawrence]

Some nice Mammatus forming to the East of Rolleston at the moment

I am seeing them too!

Me neither, but since current obs, etc already exist in this thread and the Tasman Sea trough's associated fronts, etc are what's affecting our current weather patterns, may as well keep it all together for now I guess.

Have to admit that having a general thread seems to have proven somewhat confusing when coinciding with significant events in previous months.

Awesome line of CB's over the coromandel late this evening, I do have some photos but do not do any justice to the view from here.. to top it all off, aside from the sunlit back-ends was the overshoot on 1 particular.. right down the southern end with the remainder buliding along the left flank.. (depending on which way you were viewing them.)

A bit of pileus assosciated & a whopping great jet right up there at the exhaust.
Jetstream, not plane.

Big shame they were over there & not another 50km inland... would have been a wild ride for anyone underneath.

[Tornado Tim]

Northland may get a T-storm, If the Dps are nice and high and some sunlight can get through....
GFS Chart (CAPE and LI) for tomorrow at 3PM NZDT

[Dale]

The powers that be at the metservice might want to add fog to the overnight forecast..
Absolute pea souper here with visibility barely 30 metres. The other farmhouse across the road is completely obscured from view & that is a first.

[Tornado Tim]

Same here, Full of Fog!

[David]

Pretty good visibility here. No fog here since last winter, surprisingly didn't have any all autumn this year.

[Brassnz]

I've just driven back to Auckland from Hamilton, fog pretty much all the way and especially thick around Pokeno.

[tich]

Some low cloud or fog reported around Chch sometime today and this evening, but nothing in central city. However, air must be pretty moist - no precipitation, but surfaces are damp this evening. (and nowhere near a frost)
