Canterbury Thunderstorms Mid Next Week?

Thunder · Unread post by **Thunder** » Thu 25/11/2004 17:19

Yes Jason, the moisture in the air from that preceding rain band has helped lift the dewpoint a bit. Temp is rising slightly and should get a bit higher than today's max earlier this morning of 14. The sun has just come through, here's hoping for an interesting afternoon/evening.

Yeah, Metservice added in a part of Canterbury into the thunderstorm forecast at 3:31pm just before it started in South Canterbury. Only low risk but we know it's happening, will it reach Chch though?

Batteries are fully charged so will do my best to get a lightning photo if a storm come accross.

Latest satpic shows Cb's.

Edited: 5:26pm

I like the look of the latest landcare research sat pic at NZDT 4:50pm. Shows nice Cb's behind the rainband / clearing. Nice NE here now (it's been like that all day) with the temp nearly past this mornings max. Looking foward to it!:o

I went up to the top of a carpark in central Chch (where you have to go upstairs to see anything in the distance) shortly before 6PM and could see the shower cloud well to the southwest. Don't know how long it'll take to reach here, but personally I don't want there to be strong winds combined with rain or hail between about 7.30 and 8PM, when I'll be walking to a function in the central city.

Update: cloud is moving in from the southwest as I write, but the leading edge doesn't look like giving much.

Looking forward to some photo's from down there.

Met Service severe convection + thunderstorm outlook has made no mention at all today about the Otago storms.
A cold airflow and late November sunshine always presents the risk of good convection.

There's a huge gustfront out there!!

Steve said to me he couldn't go chasing and now he is!! Bastered

, oh well. That's my Problem!! Also just to report, Stephen saw a funnel cloud but it quickly dissapeared before he got out to photograph it!! He's out there with the video camera and his film SLR around Tai Tapu so looking foward to what else he can get. Hopefully I'll get some good pics from where I am to.

The southerly change has arrived, along with the cloud. Looked like delivering, but nothing so far in the central city. But looks like storms are happening in the area.

HUGE storm coming hear thunder in distance
ye har

spwill · Unread post by **spwill** » Thu 25/11/2004 20:08

Yes, looks like a good storm to your South -SouthWest as there is a lot of lightning on the tracker.

jeffsweather · Unread post by **jeffsweather** » Thu 25/11/2004 20:29

Rain, reasonably heavy with a cold southery wind gusting to 42km/h so far.
The odd lightning strike that looks like it might be out to the west from here but I can't see any directly, just outside lights up now and then and a distant rumble of thunder.

Got very dark just after 7pm as the cloud rolled in, quite impressive.

Thunder · Unread post by **Thunder** » Thu 25/11/2004 20:33

Big gusts and constant strong wind, good rain but not overly really heavy although I believe in some parts of Chch rain would've been very heavy. I've seen some really nice Cg's but not dark enough yet to photograph, hopefully I'll get some shots when it gets darker as the storm moves up the coast. Lightning hasn't been as frequent as I'd like but thunder is loud when it does hit. I had a stirke occur about 1km away from me at one point, really cool!!!

Will put up a few pics later, the storm may be fizzeling out but we'll see?? It's a big Cb.

Edited: 8:44pm

I think it's over now. Unfortunately no lightning shots tonight. Once again the main activity lightning wise happened just South of Chch with bit's and pieces of lightning making it's way a bit further north. Out West of Chch however there appeared to be some good lightning though from other Cb's. Now to prepear the few pics I got, first time I've seen lightning and heard proper thunder in a while!

Some good rain now with strong winds.

A very nice storm rolled through between 8.25 and 8.45pm, first a nice roll cloud and strong to near gale winds, then lightning clearly visible in the southern sky, some of those pretty lacy CC strikes and some of the more pipe-like CGs. A period of heavy hail about 5-10mm for about 2 minutes then cleared and thunder and lightning moved off to the north or northeast.

Well done Ange!

Well

My origional forecast seemed to on track but the fact that we had 8/8 altostratus cover from late morning made me cancel the high likely of thunderstorm activity over Canterbury today.

My origional predictions tho' DID come to fruit tho $\:D/$
I was around at Jeff Northcott's today and we did notice aloy of electrical activity to the south

I videoed the southerly cold front's approach.
Intersesting fractus. No funnel development however

haha your wrong!!! lol

I saw a funnel cloud! just south of Tai Tapu!! I didnt manage to get my camera out in time

because by the time i saw it i think it must have been going back up into the cloud, and also those bastard of a pine trees didnt give me a good view till a good couple hundred meters down the road from when i first saw it!!!

Got some awsome photos of the gust front, ets was right underneath it!!!

Wasnt a hugely active storm, visually, but still got the old heart thumping!!

Neway im happy two funnel clouds this season!!! AWSOME

Il post some photos up tomorrow!

Good on you as well Angie/WX Girl

Good summery Tony

I videod the roll cloud and even tho' the radio was crackling never saw any lightning, maybe it was what in behind?
When the rain started it became what the MetService call thundery.
I don't like that term

Total grey 8/8 grey Nb with the occasional flash of what normal people call "sheet lightning" to the SW and west of here (Somerfield)
No hail just steady rain, becoming colder with strong southerly winds.
Weather now easing up despite the onslaught from the south

Ah HUH

My brother who lives in Tai Tapu said that he did notice 'winds going in all directions' when the southerly hit and he thought it was quite unusual?
I hope you have a picture of it Steve?

Started seeing distant lightning and hearing thunder to the SW at about 7:15 but then it died out. After that several lines of cloud started to develop overhead. There had been a moderate ENE-E wind most of the afternoon and the southerly had just arrived.

There were quite a few potential funnel clouds with the bases of the cloud lines starting to rotate and descend but nothing got too far before the gusty southerly wiped it out

I recorded some footage on video and you can kinda see what I mean from the first photo.

The thunderstorm then developed with lots of long ICs running back and forth across the sky - no wonder the Boltek was confused

Just downloaded the images from the camera and discovered I managed to get one - contrast isn't too great though.

Well, not the best photo's but something ok. Steve's photo's will be something to look foward to!! Here's 3 for now. John, unfortunately Steve didn't get the funnel on film (reread his post). Unfortunatley I got rain on the lense at one point aswell, doh!!

Thunder · Unread post by **Thunder** » Thu 25/11/2004 21:37

Last one.

Great Stuff Steven G, will add more comments later!!

I thought that possible, as the southerly came against the NE but what ever was I thought that may of happened, was rather pathetic, regrettably.

If it had been a fine clear day, with the sun adding to the instability with ground heating, I wonder what sort of thunderstorm may of have developed with the front going through

Here are two IR sat pics, one from NOAA 12 just after 7pm and the other from NOAA 15 at about 8pm.
