Quite a nice sunset illuminated thunderstorm moved in from the southeast earlier. And there's been ongoing thunder and lightning every few mins since then - though all the heavy rain has been just north of my location so far.

I got some pics of the same cell that MB got pics of, albeit from a bit further away, a different perspective anyway.. As MB mentioned it was nicely illuminated from the setting sun and went thru a broad spectrum of colours. Apologies for the quality of first pic, its my first attempt at a stitch, but you can get the general idea of the moment.

Next shows a possible guster nicely illuminated in the setting sun.

Also got a few pics of the sunset, was pretty impressive.

Pics just don't do it justice.All in all this arvo was a pleasant surprise, and tomorrow may bring some more photo opportunities, however it'll be from the front porch lol.

Had some lightning active storms out to sea tonight around the NSW North Coast. I took some photos from the Coffs Jetty area.

Enak,
The lightning certainly illuminates the structure - good stuff!
We certainly have some cumulonimbus activity off our coast this morning. Even yesterday you got the impression the mid-levels of the atmosphere were cooling and generally it was tending to becoming unsettled. During the evening there were showers that had developed - we had the edge of this shower most likely from the anvil.
It will be interesting if this is the start of another episode of activity from the La Nina - I mean where has it gone?
Regards,
Jimmy Deguara
-
Interesting Michael you even spotted a rainbow...
They're saying showers with thunder for today and tomorrow so that really comes as no surprise.
In the last few days there have been some rather interesting sunrises but they're weren't worth the trouble.
That's all from me for today!
-
I noticed that and they're now beginning to come onshore, I think in a few hours some places will cop a deluge (obviously).
La Nina is dying isn't it? I think the Bureau were saying something to this effect. Well I think these heavy showers and storms are the last remnants, although I wouldn't be surprised if this continual weather pattern follows through until winter, I made a mention of this in the general weather thread.
-
Nice photos there ppl. I like to seeing the clouds light up with lightning.
-
Great pics MB!
We had one of those great little afternoons yesterday where the humid easterly needed something to kick it off - and ridge of the Lower Blue Mountains was that. We got some very heavy rain between 3pm and 7pm giving us 37.7mm.
The sky this morning have that unstable look to it once again. And with the uppers cooling off even more so today (-20 @ 500) and heat that is generated from the sun this morning will further destablise the atmosphere.
-
Nice radar images on the Weatherzone site showing some rain on the way. I also took some nice photos not 10 mins ago well I consider them to be nice ones anyway not bad for my 1st attempt lol.

The rainfall totals are adding up - but really only at a few coastal locations so far. Ballina Airport appears to be topping the list with:
44.4mm to 9am 6/4
45.2mm to 9am 7/4
28.0mm 9am to 3pm today
Radar does look impressive with widespread showers and lightning along the East Coast.
It was even -18 at 500hPa on the Brisbane sounding Dann - similar to yesterday though the upper level dry air is largely gone now.
-
Nashua, a small location just southwest of Bangalow, picked up 68mm in the 24 hours to 9am - its wettest day in 3 months and its highest April 24 hour total since records began in 2000.
Been some half-decent showers around coastal Sydney throughout the day...typically I managed to get caught in the heaviest of the lot walking up from the station to work this morning...my socks are still wet :/
-
We were lamenting on the weekend the sort of upper temps we see now would've been most welcome a month ago....
Anyway - the updrafts here this morning were extremely solid - pileus all over the shop. I though the more saturated air might've cluttered things up a bit more - but the latest sounding shows a fractionally drier upper profile than this morning for Sydney. Interesting that Brissy shows -18, Sydney is @ -20 and Newcastle is @ -22.
The current WV image is interesting, showing a plume of moist air being dragged up from the SW over western NSW and QLD, curling around fetching a more easterly tap over NE NSW/SE QLD, while another moisture plume is being sucked up from the far SE, converging into the Central NSW coast - a fair amount of dynamism about the current setup.

I managed to take some more photo's tonight, April 7.

Enak,
That is an eerie feeling with the light illuminating the rocks on the shoreline. Two nights in a row and you have lightning nearby. Not sure if the cumulonimbus clouds here are producing anything in the way of lightning - I assume we are too distant I guess.
Regards,
Jimmy Deguara

Terrific shots of the storms again Kane - was nothing photogenic up this way yesterday or last night.
Rainfall figures for my place for the event:
15.8mm to 9am 06/04
15.2mm to 9am 07/04
29.4mm to 9am 07/04 and a further 19 today
-
The attached article and waterspout photo are probably from the same thunderstorm that Jason and I took pics of late Sunday arvo (6th April). The photo was taken at South Ballina break-wall.
-
Oh they love to use that "Mini-Tornado" terminology don't they?
I've noticed the BOM have removed "thunderstorm" from their forecasts, what for? I heard distant thunder this morning.

Hello
The showers stayed mostly coastal for most of the day. Sydney's NE suburbs scored most of the action with 14 to 20 mm falling for the 24 hours until 9 am 8/4/2008 with mostly lighter falls elsewhere such as 3 mm around Blacktown by 9 am.
For a while today 8/4/2008, I watched only isolated showers come off the coast and remain largely over Sydney's NE quadrant.
However that changed between 3.40 pm and 4.40 pm when a large single moderate to heavy shower cell passed over Blacktown dropping between 3.5 and 8 mm of rain. The shower cell appears to have developed SE of Parramatta, reached its full strength between Blacktown and Parramatta before weakening NW of Blacktown near Windsor.

A Severe weather warning was issued this morning. At the time of writing Evans Head had picked up 146.2mm, Ballina had 59.6mm and Cape Byron had 51.2mm. Still mainly coastal though with only around 25mm falling here in Lismore

Top Priority for Immediate Broadcast
NSW SEVERE WEATHER WARNING
for Flash Flooding
For people in
Northern Rivers
Issued at 4:15 am on Wednesday 9 April 2008
Synoptic Situation: 3:00 am EST Wednesday
A strong high over the southern Tasman Sea is directing southeasterly winds onto
the New South Wales coast. Combined with an upper level low over southeast
Queensland, conditions are favourable for heavy rain on the northern New South
Wales coast.
Very heavy rain may cause local flash flooding this morning.
Evans Head automatic weather station has reported 125mm of rain since 9:00 am
Tuesday

50.2mm here at McLeans Ridges till 9am 9th April. Best 24 hour falls around the area are:
153 Evans Head
103 Woodburn
99 New Italy
76 Alstonville
73 Tucombil
71 Ballina
The heavy falls have been quite limited in area with Evans Head certainly the centre of attention in the past 24 hours.
-
25.2mm here for the 24 hours to 9am this morning........ bringing the monthly April total to 60.2mm & the yearly total to a very substantial 509.0mm. :D
Good to see some awesome falls over NE NSW/SE QLD, associated with that increasingly intensifying trough.
-
20mm here since 9am with some centres around the 50mm mark in the same period.
-----
Flood Watch for the Brunswick Valley
Issued at 2:06 PM on Wednesday the 9th of April 2008
A strong high pressure system over the southern Tasman Sea combined with a low pressure trough off the southern Queensland coast is expected to cause further heavy rainfall over the NSW north coast for the remainder of Wednesday and Thursday.
Some local flooding has been reported in the Byron Shire and further local flash flooding and river flooding is expected overnight (Wednesday).
-
Ha ha, what a joke, Brisbane's Doppler radar is having "technical difficulties" again. Oh well.
Not much rain here, the bulk of it is down south, so that has allowed for some partly sunny weather, but nothing to report.
-
We had hardly any rain here today. But it did rain nearly all night plus 2 blackouts
-
Been watching the charts from down south (mexican style hehe) in relation to the NE NSW / SE Qld rainfall events over the last couple of days. Seems as if the storm season hasn't left completely up there.
Still ide love some of that rain in the catchments in Tas, Vic and SA - where it is much needed.

Have driven through some very heavy brief downpours earlier this week in Sydney, but tonight they said on the news only about 3mm in the Warragamba catchment. We have had about 25mm here at Rydalmere since Sunday morning so most haven't even this far inland, it's just not getting inland enough. Obviously the Sydney catchment is in the wrong place, and needs to be relocated. I propose placing a dam at the Heads and flooding everything under about 50m height level. After all, the rain hits the coast more than the inland.
-
A couple of isolated heavy falls overnight and into this morning 10th April on the NSW Mid North Coast. Someone reported to ABC radio 148mm at Sandy Beach - north of Coffs Harbour. Nearby BoM sites in the region are all around 50mm but I do not doubt the report.
One site in the Port Macquarie area has possibly copped some heavy rainfall. Port Macquarie Dam reported 75mm in one hour to 7am and 36mm to 8am, with a 23 hour fall up to 188mm. Newcastle 256km scale radar shows significant rain in that area over a few hours so the isolated heavy readings are possible. ABC Mid North Coast which is based in Port Macquarie also commented on very heavy rain.
