Must be terribly hard to forecast snow levels. For perspective, the sky tower is about 320m from ground to spire tip I think.

[snowchaser01]

Metservice now say 100m on Christchurch Rural forecast... hmm

[mikestormchaser]

I still think snow showers for the city. If snow showers can form a chain during witch it is the coldest part there may be a couple cm accumulated. I'd keep out on maybe a gust front with approaching SW change this afternoon. Could be something to watch maybe

Wind seems to have become southerly here now.

Raining steadily in Greymouth

Going by the latest models this afternoon. Nothing has changed moisture wise and still to me looks cold enough for snow to ground level

Some nice mammatus over Chch..

Nothing heard here as I about town at the time the southerly picked up and it came onto rain.

It has been dry in Dunedin most of the afternoon, even with a patch of blue and a flash of sun. Now looking "thicker" south of here. Maybe as the sun goes down we will hopefully be in line for a cell

Snowing in Mt Somers nicely, not big big flakes or nothing but just general snow

Good snow with big flakes now.

Just driven home from Chch to Waddington (nr Sheffield) and on reaching the Darfield turn off on Old West Coast Rd (c. 300m) the rain turned more sleety and wind picked up.

EDIT: 5.40pm first few flakes amid sleet.

EDIT: 5.50pm - snowing

I can't get over how fast the temp is dropping here, 5.5 to 4.3 in less than 10min

Friend reports it is snowing in Kirwee.

Snow settling 5 km west of Ashburton approx. 140 metres but radar shows it clearing from the south

[NZ Thunderstorm Soc]

It looks like it's allover down here. Roll in the next system next week

Just got back from Akaroa. Light rain was starting there just before 4pm, but no snow or sleet yet at Hilltop about 1/2 hour later. (probably some there now)
