I'd watch out for TV3, Jim Hickey could come out from his cafe to haunt Toni Marsh

Clearing slowly out although still the odd shower about going by 9pm radar.
Once again I will be going for the same as few weeks ago possibly few snow showers in the morning with it being cold enough but we will see.
2C outside now still dropping southerly breeze.
Cheers
Jason.

Sheesh looks pretty wild in the Wellington region this morning!
Southerly gales and heavy rain set to continue right through to Thursday night by the looks!

Quite possibly, with temps in Chch only just above freezing around dawn, and some light precipitation, though I only saw a liquid, drizzly shower about 8.30am. But I notice there's a light dusting on the Port Hills down to about 200m.

I notice there's some snow in the grass and a few mm on cars here in Templeton, so it got down to 40m overnight

There was ice that looked like snow on the temporary roof (black polythene) outside our windows here at work near the airport this morning but on closer inspection, it looked more like hail.

We had a bit of snow on the ground when I got up this morning.

Some dark grey clouds forming out now threatning rain is spitting too.
Currently 4.7C southerly breeze.
Very Overcast in Hanmer by the looks of the webcam I would say it is raining maybe even snowing can't see the hills.

It looked really good on the GFS model runs at the weekend but by last night the forecast thickness had increased and by today it was up at 530dm

I guess what happened was that the rain band came and delivered the wet stuff to Canterbury on Tuesday morning and then moved off to the north before the very cold air arrived that night. (which brought snow to low levels, but only light falls) If the coldest air had arrived earlier, before the rain had moved on, then we'd have got heavy snow to low levels. That must've been what was originally predicted.

I work on the theory of the barometer.
I think that the barometer was too high on the surface for anything major to happen

Going on what I said before about Hanmer apparently it did snow off and on there today.
Which doesn't surprise me either as it was 2C maximum there today.
Not sure what elevation Hanmer is at id say about 400m.
But anyway tomorrow looks set to be a repeat of today or should I say today considering the time

.
Then roll on the relativly mild few days after that with NW winds until Sunday when it packs again.
Cheers

Not too different in Chch now - about 4C with low cloud/mist and some light drizzle.

Just looked at Hanmer webcam - 3.2C there at 11am, with thick low overcast and probably raining or drizzling. (maybe just a little too warm for snow)

yeah as i said on the other post it is very cold and overcast. and if it had been raining today i wouldnt be surprised if it snowed.never know it still might. because what i got told it was just 2C at midday.

Snowlover · Unread post by **Snowlover** » Thu 06/07/2006 14:15

It was 6 degrees in Redwood at midday. Barometer is dropping tho. Don't think it will snow
