Just got home from my chase, Will put up a report and some photos later..In a nutshell would be up there with one of the better chases in a while. Not much on the side of lightning but the wind and rain as it hit omfg! not to mention some nice structure.. A lot of tree damage in the area aswell as lines down and a few power outages here and there. Want to sus out a few obs before i do up a report. Can anyone post the link to the site that holds the radar archives? Few of the cells had nice rotation and one with a bit of a meso that tried to get goin near williamtown.

Ohh and nice pictures Hunter..Love the roller-guster.

And i'd believe 96+ winds here at home due to the amount of trees and debris everywhere and the fact i almost got blown off my roof! So need to get my weather station working with the pc again soon!

Glad to hear you had a rewarding chase. Here are two of the radar archive sites that I know of:

Nice Photos Hunter
Storm No 1.
This strom produced some fairly strong winds & heavy rain in Hawks Nest


The back end of storm No 1.


Storm No 2. In its early stages.


Since i was at work and could'nt chase, i thought i would sneak out in a cart to the 18th tee to capture this pano.
Looking SSW towards Nelson Bay.

Nice photos everyone! If I had a camera on me, I could've taken a few photos of the storm at Charlestown but unfortunately I didn't have one frown

Edit: Anyone looked at the Grafton radar? The cell near Woolgoolga kind of looks like it has some rotation going.

I reckon there could have been a couple of isolated 120km/h wind gusts out there today, probably somewhere on the North West Slopes & Plains.


Hello, I'm new to the forums (but a long time lurker :)). I was in Kempsey CBD this afternoon when the storm hit around 6.15pm - the wind caused blackouts in town (due to a tree down on powerlines) and here at home we managed 15mm from fairly moderate rain (yellow and orange blob over us). Plenty of lightning and thunder - tree branches down in West Kempsey but no damage around here (plenty of large trees), which was lucky.

Enjoy reading the posts here and learning a lot about the weather from everyone too.

cheers Thundakat

With non doppler radar you can not for 100% certainty say a storm is rotating (or not) and even with the higher resolution dopplers and looking at the velocity winds, unless you know what to look for its not easy to pick it either.. Its the same when viewing supercells on the older radars like grafton, it is very hard to determine a hook echo (which would indicate rotation within a SC) but the dopplers being of smaller wavelength and finer detail these features can be seen easily... either ways, the storm/s your refering to don't show any indication of rotation on grafton radar and i doubt if it was a doppler, you'd see it either... nothing overly fancy with that storm other then it building on its NW side - indicative of a multicell storm embedded in a convective line of mess.

Now, apologies if your already fairly knowledgeable with radar etc, but i just want to show an example...apologies for the OT chatter too.. but here goes...

For this example i will use the new Namoi radar... the day after the Namoi radar went live a Supercell passed just to its north, exhibiting a classic shape, one that typically eludes us on the lower resolution radars (and even on the higher resolution dopplers, this example would have to be the best i recall seeing) (OH, its one a US Chaser would be "all over" if it was the US Plains ;))...

Here I've linked the radar and doppler winds so you can compare the rain radar with the wind velocities.. note the pronounced hook through a great deal of its travels past Gunnedah. (in fact, i would suggest it has a hook from 1:10pm through to at least 3:30pm - and doppler winds indicate it still has rotation before even after the hook feature is there..)

So here is the 128km Rain Rate:
http://www.theweatherchaser.com/radar-loop/IDR693-namoi/2010-09-14-02/2010-09-14-06

128km Wind velocity:
http://www.theweatherchaser.com/radar-loop/IDR69I-namoi/2010-09-14-02/2010-09-14-06
(the time around 2:04pm and 3:04pm probably give you the best examples of what to look for on doppler for rotation)

AND for a close look at the hook, 64km:
http://www.theweatherchaser.com/radar-loop/IDR694-namoi/2010-09-14-02/2010-09-14-06

and for comparisons sake... Moree radar at the same time, showing bugger all frown :
http://www.theweatherchaser.com/radar-loop/IDR532-moree/2010-09-14-02/2010-09-14-06
(granted, its ~160km from the radar, but you get my drift)

Anyways, as you can clearly see from that example, a lower resolution radar - even if the storm is close to it, does not have the same level of detail to pick up the hook features that would indicate rotation, and sure don't have the doppler winds to confirm it anyways... another example i would have liked to have shown was the Myalla Tornado and Radar loop from Canberra's non doppler radar, which looks nothing like the Namoi SC, but had a confirmed and photographed Tornado... but will save that for later if you so wish to see it smile

Only managed 1.1mm in Tea gardens from yesterday's storms, while at the Golfy recorded 5.0mm and over at Nelson bay 11.0mm.
We only got the edge of the storms, but the wind was very impressive.
Here is a 2min clip of yesterday's storm, "beware the quality is crap"

We had 6.8mm in the 24 hours to 9am from yesterday's storm. A STW has been issued:
SEVERE THUNDERSTORM WARNING
for LARGE HAILSTONES and DAMAGING WIND
For people in parts of the
Mid North Coast, Hunter, North West Slopes and Plains and Northern Tablelands Forecast Districts.
Issued at 2:17 pm Wednesday, 2 March 2011.
Severe thunderstorms are likely to produce large hailstones and damaging winds in the warning area over the next several hours. Locations which may be affected include Armidale and Ebor.

We have already had one of those "big drops, widely spaced" showers (lol, that's a technical term poke ), so there's only just a trace in the gauge.

Simon: Thanks for all of the info smile I do know what features to look for in radar returns to define a supercell/rotation but I'm not always certain when looking at the radar whether there is one, so I'm happy to learn. Thanks again!

A storm is moving in here as I type, with rain increasing. Lightning is fairly regular and there have been a number of big booms of thunder in the last 15 minutes. It's pretty much dark now, so we're in for a night time storm treat. grin

We've had 16mm here this evening from two thunderstorms that have passed over. A few showers and the possibility of a storm is once again on the cards tomorrow.

Just had brief but heavy downpour. 6mm in 8 minutes! 23.2mm in the gauge now. Surprised there wasn't any thunder/lightning.

A brief as possible report from Tuesdays 1st march chase, sorry mods or those on low bandwith if its to long..

Part 1 Glendale.

I was expecting a bust chase day again due to a couple of family commitments etc and the skies weren't looking too exciting for the most part of the early afternoon, And once the first warning for the Scone cell coming in at 1:30pm i was expecting most if not all the action to be to far north to bother about..The sky started to take on a interesting and exciting look around 2:00pm

First cell from Gateshead looking north at 3:14pm that had recently dumped its load on Charlestown.


Come 3pm the cap started to give way along with the stiff N'wester and thankfully it had not dried the air out too much..Picked the son up from school and within 15min the skies went from meh to hmm...

2nd cell from Gateshead looking west southwest 3:09pm


On the way back home to pick up the step son to drop at Newcastle airport coming down into Cardiff a nice base and rain shaft took my attention , with a nice lowering infront of it,. half expecting the shear to push it over southern Lake Mac but tried to get home to get some shots of quickly before i hit the road again.

2nd cell Cardiff heights looking west southwest 3:28pm


Stopped for a quick splash of fuel in Cardiff and looked up and was greeted with the view of a partial one eye green monster..(well not huge but looked nasty), Hurried the missus and son out of the lolly isle and into the car to try and beat this thing home -700m away from home- as it was getting close and fast..

2nd cell Cardiff BP looking south southwest 3:34pm


A few minutes later i arrived home and scurried to the roof for a quick snap,..Tooo late..
Managed maybe 4 shots then took over with the Ph video as the wind and rain hit, And talk about whack! I can honestly say i haven't confronted a Mircoburst with this much ferocity in many years..I took 1min of footage huddled between the laundry roof and the eave of the house. Decided it best be getting down with the 1000d getting a good wash along with myself.. i decided it best i jump,..in the process i had turned off the vidcam without realising and missed the best footage possible huddled against the house hoping it'll give in enough to run the 4 mtrs to the door, the wind was at this stage blowing good sized gum tree branches past the house and god knows how much further up the block -closet gums to here are about 500m away..

2nd cell Glendale looking west 3:37pm


2nd cell Impact video Glendale 3:38pm 1:09min
Link to Video as i dont know how to show them as eddy and others have


more to follow,

Part 2, Glendale-Williamtown

For the size of the rainshaft which was rather small had some power behind it, i estimate a good 90+ possibly over 100km gusts at its peak and about 30mm over about 30min most of that within 5minutes. Small soft hail in the mix, and dropped the temp from 36 to 21 within 10minutes. Once the surprise attack was over i checked the radar quickly before heading off for the airport and to keep up with this cell that was growing by the second..Not so lucky at keeping up due to the debris all over the place, traffic lights out, peak hour.

2nd cell Glendale 3:50pm


2nd cell Sandgate looking north northeast 4:14pm


2nd cell Mayfield west looking north 4:21pm


Just prior to the airport watched the tail end of the cell that hit home head out to sea and watched the back end of the guster that Eddy nailed, on the way up I had noticed a bit of Cu getting its self into gear further out west, to me (im not expert so any input is appreciated) it started to spin up and was taking on a bit of a solid rain free base with a meso look to it and a bit of a wall cloud..If I wasn't pressed for time for the airport I would have done a little bit of timelapse to show the rotation better.

2nd cell Fullerton cove looking east northeast 4:35pm


3rd cell Fullerton cove looking west 4:37pm Possible Meso with wall cloud?


3rd cell Fullerton Cove looking west 4:37pm


Once I had dropped off at the airport I stopped at the first clearing to try and get video of the possible meso turn supercell..Snapped off a few photos while taking about 15min of vid, Unfortunately it was starting to outflow, this is the cell that the media have dubbed the Medowie mini cyclone,..but I wont go into the mini debate...Managed to do a little damage out that way,If it was a MCS be it the garden variety and not a Us mothership then perhaps labeling it cyclonic but it wasn't so mini, uhmmd n rrrrd whether to stay put and save fuel and just watch it drift away or try and corepunch it...

3rd cell Williamtown looking west 4:49pm


Decided to try and sideswipe it before it hit the Bay but before I had arrived to Cabbage tree lookout and sorted out a SD card issue it was already ocean bound and sucking up some juice, contrast wasnt the best so didnt take many decent photos. Got some the vids to edit from the airport and lookout as I nailed a few decent Cg's, a couple hitting Broughton Island and are hopeful they are worthy of a screen grab. After listening to the cell grumble its way out to sea and before deciding to head home a little turkey popped its head up behind the main line..Risking staying and it fizzing out and needing a blood transfusion decided to pull the pin and head home.

Part 3 Williamtown-Nelson bay-Stockton,

2nd cell Williamtown 5:00pm


4th cell Nelson bay looking south southwest 5:47pm


3rd cell Nelson bay looking northeast 5:51pm


In typical fashion, that little cell decided to grow and grow fast, by the time I had made it to Stockton bridge it had started churning away nicely, It had a nice rotating updraft and inflow band, this is probably the back end of Hunters Guster-roll cloud photo,. Stopped and snapped off a few shots and again should have videoed it for a while but the sandflies were rampant..Just as I hit the road got a call to say the southerly had just thumped its way through the central coast, Thought I might as well sit it out at the windmill and wait for it to hit,.Glad I didnt stick around as i'd still be waiting, It hit with enough force to ruffle a leaf.

4th cell Salt ash looking west north west 6:27pm


4th cell Stockton looking north northeast 6:42pm


All in all a great day, 4 hours chasing 4 storms, 150km driving and only set me back 30bucks for fuel.. Sometimes those juicy days that tend to get ruined by commitments work in your favor. Had I left home ten minutes earlier I could have corepunched the better cell of the day for the better part of 50km.

Again sorry for the length etc,

will add the videos once I get a chance to edit them and the rest of the photos into a album once uploaded..

We've had some thundery rain here this evening, with 7mm so far. A nice stormy start to March. 4 storms in 3 days, including a severe storm on Monday with 91km/h winds recorded. In the first three days we've had more than half of our average March rainfall already.
It is currently 16.8 degrees and raining lightly.

With the intrusion of drier air, and the trough moving away from the region, only a shower or two is likely tomorrow. Then some drizzle or light showers during weekend in the SE'ly onshore flow of showers.

Call me crazy, but the sky has that pre-storm look about it this morning. Humidity is back after the westerly yesterday, with 'light winds' forecast we may see something develop somewhere. The BOM aren't having any of it.

Great photo guys looks like the day was well covered!! Although there was no turning (hence no supercells) down in our parts there was some nice dry air aloft and some rather strong shear, would explain the widespread strong winds from the Hunter north! I agree snow4syd, there is some cold air surging up the coast today, later in the evening we should get some isolated showers maybe even a rumble or two. Interesting to note, according to the BoM's media releases, Sydney airport has only had 7 storms all season - 4 in spring and 3 in summer, well below the average of 17 for the same period. Believe it or not last season people were complaining about it being the worst and we had 22 storms over spring and summer, so I think this one takes the cake for the worst, although out of Sydney it has actually been pretty good!
