Australian Severe Weather Forum

Another round of severe weather warnings have started - for parts of NSW and VIC at this stage but we could see more widespread warnings soon enough. Flooding continues in many of the Tasmanian rivers and the week ahead looks very wet again. Meanwhile temps will be approaching the mid 30s over NE NSW and SE QLD tomorrow (Saturday) before there is finally a change.

Locally, it's been almost 2 months with no rain at my place. This is not all that unusual this time of year but frustrating none-the-less.

We are forecast to have a windy day tomorrow with isolated thunderstorms and rain areas.
Today was such a beautiful calm sunny day, but some more rain would be great. I'm just not looking forward to more windy weather. The wind last week caused a few big limbs to come down and all of the kid's outdoor toys ended up out in the paddock next to the house.

I'm looking forward to this trough & front!

Not liking this heat that is preceding it however. I'm frantically getting some painting done on the interior of our house before the moisture rises.

I noticed quite a few widespread storms firing in SA yesterday evening with this change.

Russ is off to Sydney tomorrow so I'm bound to get something out this way lol. He'll be ready to photograph anything that he comes across on the journey down.

Take care guys,
Shauno

So far the only warnings in Vic for severe weather is for the alpine district in the NE. But that may change, once the system moves in. So far tonight there has been about 0.3mm in the home gauge. Not much, but a nice light shower nevertheless. Still, if the storms come in, it will be worth a few pics. But as I found with the last storms, capturing the few excellent thunderbolts was almost impossible.

Was an excellent late winter's day here - got to 20deg C for the first time in ages!!

Hi all,

Just thought I'd update a couple things here currently. It hit 36 degrees C at 1:58pm (EST) and the wind gusts have been very strong all day with several large branches brought down around my area alone. Seems to be the odd cell here and there but it looks very grey and highly dusty so it will make it a little hard to discern any significant storms cells for the moment. I will keep an eye on the radar however.

We've had the odd light shower but nothing great as yet.

Looks like a squally pattern is the order of the day.

Best of luck and take care if you get out in it!
Shauno.  

Again, GFS is over doing the instability west of the ranges. dp has crashed to 4C at Moree with a temperature of 34C. Those bases are going to be sky high. Moisture in SE Qld is much better but with warm mid/upper level temps (for winter) there really isn't to much CAPE to work with. Replotting the Brisbane sounding for 28/18 only gives about 500j/kg of CAPE with a weak cap remaining.

SOUTH COAST,
SOUTHERN TABLELANDS,
ACT and
SOUTH WEST SLOPES Forecast Districts.

Issued at 4:23 pm Saturday, 29 August 2009.

Late edit : update on severe thunderstorms warnings, Northern NSW has a band of stroms approaching the east coast. Warning from BOM

For people in the ACT and parts of the SOUTH COAST, NORTHERN TABLELANDS, SOUTHERN TABLELANDS, NORTH WEST SLOPES, NORTH WEST PLAINS and SOUTH WEST SLOPES Forecast Districts.

Issued at 5:24 pm Saturday, 29 August 2009.

Severe thunderstorms are likely to produce damaging winds in the warning area over the next several hours. Locations which may be affected include Canberra, Goulburn, Armidale and Moree.




Looking at current radar and charts, and as BOM has mentioned in latest update, it seems to be tending towards strong winds as the main threat.

Interestingly I had two email warnings from EWN this morning waiting when I woke up about the forecast gales. Got quite windy here, but not too bad. Still gusting a bit but not as strong as this afternoon.

Hi guys,
I had no luck yesterday evening with any weather other than a few slight showers (much as today). The temps are definitely down on yesterday's brief summer preview.

I wish I could have bee down near Coonamble as the storms were really firing down that way! I heard one solitary rumble of thunder at 12:25am EST that woke me from partial sleep and got me all excited! "A storm! Finally after all this time" I thought. So I started going through the usual chasing check-list and stood out on the verandah to see what was actually happening and in which direction, only to not see or hear anything again? That was it. lol!

I wish the season would begin out here already as the suspense is killing me

Kindest regards and take care,
Shauno
