Unstable trough

Unread post by NZstorm »

Trough due across the country Wednesday looks cold and unstable.
Thunder/hail likely in western areas. Also, slight chance of thunder along eastern coasts with southerly change.

Thankyou! Thankyou!! Thankyou!!! :D

I'll take some pics if anything happens 8)

By Western areas, does that include the western parts of the North Island?, I guess we'll find out tomorrow. I see great pictures in the near future!

Very, very slight chance Aaron. Sorry to be a Kill-joy :(
Probably just grey stratus as the colder air moves in, unfortunately :x :x

Yes, thunder likely over the west of the NI today. Infact, looks like a Tstorm over Taranaki this morning. Foggy in Auckland at the moment.

Snow level in Southland/Otago today looks like it could be as low as 300m, much of it nearer the coast though.

Dunno if this really applies, but i'm sure i could see the beginings of the trough while flying at 32,000 ft yesterday.

There seemed to be a cluster of cb's (quite well developed) about 2-300 kms off shore (as in off the taranaki coast)

could this be related, or simply a local event?

Just after lunch and into the afternoon I see good chances for thunderstorms up North. Take many pictures people!

Yes John, I know :( ........ But, there might be some drizzel! So that will keep the drizzel division of the NZTS on the move.

Some interesting looking mammatus cloud to the north after about 4PM. It seems the cloud is thickening from the north, while I have been looking south, wondering when is the southerly front coming? The southerly has obviously arrived, but, as is usual in Chch, the rain hasn't. In a southerly rain normally comes later than the wind change, if at all. But it certainly feels colder - about 8C.

MetService seems to keep changing the snow levels in today's forecasts. The short forecasts forecast snow to about 900 metres in the eastern NI and 600 metres in Canterbury. But the National Radio midday long-range predicted snow by tomorrow for the Rimutaka Road (highest point about 550 metres asl) and Napier-Taupo Highway (about 800 metres at summit), while forecasting snow down to 700 metres on the Kaikouras. :?

A very active thunderstorm reported from home, but I was unable to get out of the office early - so no pictures from me :(

On the drive home there was a very large anvil at the southern end of a line of storms heading off to the north east. There are a couple of anvils around to the north-west of me here, just waiting for the 6pm satelite image to see if there are any more.

Cheers,

G
