Shower of graupel through home, everything white very quickly. Settled well

Just home from visiting friends a little way up Leith Valley approx. 100m ASL, a good covering there and blizzard conditions all the way back to centre of town. Snowing again now in Northeast Valley at 60m ASL

Interetsing

Fine and calm, here with clear skies, frosty though.

Got work at 6am and have to get over Highgate which should be interesting. How long until they shut the Northern Motorway I wonder. Octagon webcam shows no snow.

I hear Three Mile Hill is closed, and its coming down hard again in the hill suburbs. I don't like your chances other than on foot tomorrow morning. Even if the snow stops with these temps it will now be treacherous on the roads.

Same in St Albans. 0C at Jeff's station, so not surprisingly the precipitation is of a frozen variety.

Fine and frosty here overnight too. I just checked metservice and they are still saying "Showers developing this morning, mainly north of Geraldine, with snow to sea level, rising to 200 metres by midday. Southerlies, strong about the coast". I've just checked the rain radar and all the action seems to be out to sea.

Issued: 3:55am 8 Jul

I've just checked the rain radar and all the action seems to be missing us here again. It is absolutely freezing cold outside, I noticed last night was the first night I actually saw my breath in the air in our laundry, I've never seen that before in the two years we have lived here in Rakaia.

A bit of light snow here overnight enough to make things white. Temp -2.

Must have had a brief snow shower before the frost came through in east Christchurch overnight. The few flakes we got last night have frozen solid.

That was right across town, most parts of ChCh got a very light dusting on top of the earleir graupel. Certainly in the SW of town and the Central City anyway

Did you get a bit over your side of town too? These chain showers are only just clipping us over here. It was snowing again here for half an hour or so about 9am. Brilliant sunshine now.

petem8nz · Unread post by **petem8nz** » Wed 08/07/2015 09:42

2 reasonable showers about to skim through for the whole city in the next hour looking at the radar.

RichyDunedin · Unread post by **RichyDunedin** » Wed 08/07/2015 09:43

Had about 5cm at home when I left at 6am, only slush at sea level In town really but was some very bad black ice too. Quite heavy snow showers on the hills all morning. Made it to work over Highgate though almost slid into a car after another car had spun and blocked the road. Northern motorway has reopened to cars but not trucks or towing vehicles.

Yup my run to work took me through Hoon Hay, Spreydon, Addington to town. Snow lying on the footpaths (patchy) the whole way, but clear conditions. All the action out over the Peninsula at present

Sleet and hail is probably the best the city will do tonight. Anywhere above 150m should get settling snow. The showers dont really start coming in until early afternoon. Even late afternoon.

Storm Struck · Unread post by **Storm Struck** » Wed 08/07/2015 11:18

There is a chance of some flurries down to around 100m overnight but it wont settle, could get some good coating lower down from graupel and sleet though.
Remained dry as a bone in Rolleston overnight

No precipitation here so far just a very dry cold WSW wind and mostly sunny. Pano of the Port Hills about 45 minutes ago.

Yeah I think since Saturday iv felt this would be the usual set up. Just a cold winter southerly. Im never going to be up and arms over events unless im absolutely convinced things are going to happen. The reality is chch and Canterbury sea level snow doesn't happen often. on the odd occasion a set up whether its to do with thunderstorms or snow, just sometimes "sticks out like dogs balls" and you just know its going to happen. Its not been the case with any of these past events. Except if you live in land of course for the big snow dump.

A good summation I reckon. Substantial sea level snow in ChCh is a) a fickle affair at best and b) a relatively unusual occurrence

Yes for me we need a good warm advective snow event set up or a wind convergence zone that hangs over the city witch draws the narrow shower band right into the city. .taking that topography impact that BP has away. "Its not often it lines up like this very often" but when it does its normally pretty significant. Thats canterbury for ya

I see metservice have upped their precipitation numbers to over 20mm. The Port hills and Peninsula could be in for a hiding over the next 24-36 hours

Ended up getting 5cm's yesterday morning which then melted but very heavy snow moved in about 3 yesterday afternoon giving us another 15cm overnight. So easily the biggest dump of snow for us since probably the big snow of 2013
