Thundery midweek too

Unread post by tich »

Valid to: 12:00 am 17 Nov 2005 NZDT
Issued at: 9:37 am 15 Nov 2005 NZDT

Conditions are expected to destabilise again over central and southern New Zealand from Wednesday afternoon as temperatures in the upper atmosphere cool.

In the South Island, the most likely area for thunderstorms is about the south coast in the late afternoon and evening as a weak cold front moves through the area. This front should bring heavy squally showers, thunderstorms and some hail. It is possible one or two of these thunderstorms could also affect Fiordland and southern parts of Otago on Wednesday evening, but the risk is considered low.

In Canterbury, a southerly change should move through around the middle of the day. There a low risk of a few thunderstorms with this wind change, with the threat level being slightly higher in North Canterbury, however an expected northwesterly flow ahead of the front means there may not be sufficent low-level moisture to allow thunderstorms to develop.

In the North Island, a front will move across southern areas in the evening. It is likely this front will contain a few embedded thunderstorms, particularly about the ranges, along with a brief period of heavy rain.

I mean that the piece quoted above by Ben sounds exactly like the sort of thing you write on here... Perhaps Paul and his mates have been taking notes ;)

End of week thread probably irrelevant now, as the outlook appears more settled, except in the far southwest. Tomorrow now looks like having the only significant chance of thunderstorms for NZ for the rest of the week.

No nothing from this, :(
As the statement from MetSerice said that the moisture level at low levels would be low because of the NW influence preceding the front..
Could? be a weak Gust front though like the other day :)
...that depression seems to be a 'Gone-burger" :D

Rain band reached Timaru about 10am. Slightly lower cloud than the existing northwest arch is moving in from the southwest in Chch now - southerly change must be near.

I had light snow hitting my windshield at Twizel this morning, and there's plenty of fresh snow on the hills too. Around lunchtime in Omarama there was a prolonged hailstorm, but I missed that one.

Skies darkening to west and southwest, with some spits in the last 20 minutes. I wouldn't be surprised if a thunderstorm is coming.

Snow is only forecast to about 1000m on the Southern Alps, Twizel is only about 500m? Southerly hasn't been really cold yet in Chch - about 12C now.

Heavy rain showers in Chch since just after my last post. I thought I heard some rumbles, but more likely to be large vehicles in rush-hour traffic.

Most snow would have been at the 800m level I'd say, with some extremely light dustings below that. Twizel only copped a glancing blow, but enough to land on my windshield! :)
