BLEAK Week a coming!
Looks likes a BLEAK week coming up for Christchurch from Sunday onwards.
Lots of calm, dull, boring cold days as the Se dosen't get blustery in and over Christchurch because of BP.
Interesting to see what rainfalls we get from it.
Could be a great snowfall dump for the end of the ski-season tho'

At least we're getting an advance warning. I think if it's a southeasterly, Chch will feel some sheltering from Banks Peninsula, so not that much rain likely in the city. Anyway, ultra long-range (UNISYS) is going for a change to northerlies or northwesterlies for next weekend. Here's hoping.Looks likes a BLEAK week coming up for Christchurch from Sunday onwards.

Looks like there's some very cold air behind the front due to move onto the South Island on Monday. However, the models seem to predict it to shoot up into the central Tasman (528 thickness line reaching right up to about 38S), rather than onto NZ. Would be interesting if this very cold did move onto the country. Anyway, warm advection snowfall could still lower the snow levels in inland Canterbury if there's enough moisture in the airflow. I think we're far from the end of the ski season.Could be a great snowfall dump for the end of the ski-season tho'

Looks like there might be a few cb's about near Auckland today from Satellite pic, below:

Good luck Steven, perhaps a few photos later today to add to your awsome collection.

If they aern't Cb's I don't know what else is! Good unstable cloud out to the west of the North Island, still not near land yet but they look good don't they. Micheal, get your fan and set it on high, stick it out the window and blow some those Cb's down here if they get to you! hehe

There's some interesting features in this satpic, look at the well organised lines of CBs advancing onto the SI east coast from Stewart Island to about Oamaru, and notice how that line disappears into a sort of hole in the low cloud east of Timaru. Look also at the very sharp boundary of cloud over the ocean from Timaru up to Banks Peninsula.Aaron J Wilkinson wrote:http://satellite.landcareresearch.co.nz ... d08093.jpg
In the North Island you can see a similar, very well organised and narrow band of showers from Cook Strait to Hawkes Bay.
It will be interesting to look at the NOAA pix from this evening to see if these features are still identifiable and how they have changed/moved.

Heavy rain has eased off here. Upper air must be getting more unstable now. I think the worst of the unstable weather in the Tasman Sea will be flicked over the top of the NI by the low and I will be left with the crumbs to observe tomorrow. But Wednesday could be more interesting as skies will have cleared significantly and the upper air still unstable. Surface heating could trigger some cb's. Still abit early in the year though but there seems to be some real heat in that sun now. So heres hoping.
Re Tonys comments on the east South Island cb line. I agree a very strange looking cloud line. I am sceptical this is convective cloud though.
The environment down there is still on the stable side, thus I am thinking this is thick cirrus. I can imagine a cloud layer of that scale in the higher atmosphere but not near the surface.
Latest sat pic has the thundery front in the north moving onto the top of Northland.

A cold, wet morning here in Chch, only about 5 or 6C. I'm surprised MetService hasn't issued a road snowfall warning for the Lindis and Porter's Passes - the cold precipitation should be reaching there in this southeasterly flow, and snow is forecast down to about 500-600 metres.
You know what that could mean this afternoon.temperatures climbing here due to sunny skies over the waikato, even though we have high cloud blocking the sun out

Yes Brian, the Met service prediction of morning rain did'nt come off with the weather turning fine. But T/cu quickly started building with a scattering of heavy showers developing by early afternoon with hail and
isolated thunder. A few of the showers become very heavy and I photographed some nice thunderstorm structure over East Auckland where I was working today.

great photo!
we only got the edge of the showers here, as we had a southerly running up the coastline...
the area between the SI and the chatamns should be renamed the roaring easterlies there has been so many easterly winds there
the beaches on the east SI must be changing with all the easterly surf?
