I noticed the temperature dropped 1.5C in half an hour there Dean?

Yes 1.3 now.... lost a couple of degrees quickly when the snow started to fall.

Just drove back to Christchurch from Methven an hour ago. Went home Thompsons Track Snowing in Methven with large flakes well settled on the ground. Snow stopped at Lauriston turned to sleet rain, then rain all the way to ChCh

Latest MS warning:
Heavy Snow Warning
AREA: MARLBOROUGH SOUTH OF SEDDON AND CANTERBURY NORTH OF THE RAKAIA RIVER (EXCLUDING CHRISTCHURCH AND BANKS PENINSULA)

Starts: 10:00am Sun 8 Aug

Ends: 9:00pm Sun 8 Aug

Snow is possible down to sea level, and is expected to become heavy inland above about 200 metres where 15 to 30 cm of snow is forecast to accumulate, or possibly more at higher levels. Note, snow showers are likely to sea level tonight (Sunday) and Monday morning, these may affect Christchurch and Banks Peninsula.
Heavy snow may disrupt travel in affected areas and could damage trees and powerlines. Cold conditions may cause stress for livestock.

The old "Band Van parked up in Methven The snow started 40 mins before the pic was taken. We were playing at the Blue Pub last night, it was 4 degrees and had just clagged in when we packed out of the pub at 2am

A mere 1.8°C here and snowflakes falling steadily.

Sleeting in Kirwee now,just started.

[Bradley]

It’s 3C colder in Darfield up the road then here in West Melton, how’s that even possible with only 100m difference in elevation?

[MoorfNZ]

Reports that it is now snowing as low as Kirwee (157asl)

There is Suttle differences which make big differences, the sea often warms the eastern fringes but the further inland you go it starts to rapidly cool. Which lowers the freezing level there. It will also depend how heavy the precip is with the evaporative cooling affect

If the coastal plains/ chch gets snow it won't be until tonight/ Monday morning. But hey.. for weather enthusiasm sake I hope we get a surprise

[Lawrence]

Fairly decent snow flakes now, quite vigorous and moderate.

Currently at My Parents House in Ashburton. Been getting Snow showers coming in waves for 5-10mins but not settling then turning back to sleety rain, Feel like were right on the edge of the snowline. Apparently 1-2cm of snow at Home at 100m in South Canterbury But clearing up.

+2.3deg in Amberley and sleety. Splogey on the wind-screen.

I see Niwa has posted a model showing some snow in the Waikato ranges

Will keep an eye on any light showers that might come through on Monday, but this is likely the GFS being a little "approximate". I'm yet to witness anything close to grapukel or snowflakes around here as was on holiday in Queenstown during the 2011 event. My parents say some definite snowflakes mixed with rain fell for about 5min in about 1980. On the farm at 60m ASL just out of town.

Radar looks to be bringing the clearance of the rain back towards ChCh now. We await the southerly change with much interest tonight

[Lawrence]

Looks to be all over here for this part of the system, snowline looked to be around 150m asl so EC did very well in that department…

[Wildland]

Heavy rain with a thunderstorm at 9 o'clock this morning here in Tawa, north of Wellington. Steady rain since but holding at ten degrees for now. Keeping an eye on Colonial Knob whenever it appears through an easing of the mist and low cloud to see whether any snow accumulates later today or overnight. The gusty northerly has eased somewhat.

It has been wonderful watching the snow out the window at work (supermarket) but of course it brings in all of the apocalyptic panic buyers. It has stopped now but hoping it starts again this evening.

[TonyT]

Snowing properly here now with temp +1.6. Seems to have spread towards the coast a little earlier than modelled.
