With that cell at Maroochydore, I can attest to the fact that we got hammered big time with microbursts and whiteouts. It was pretty nasty and full on. Now another cell is over us, but it's much calmer and the rain is falling steadily.

Sydney storms 16 December 2010

During my lunch break today, I was able to go up to the top level of the Auburn Council car park and photograph some storm activity over Auburn. The two photos provided are looking north from Auburn. During this time, a reasonably heavy rain shower was occurring and thunder was audible so I had to be careful of not being on the car park roof for too long.

Not long after I took these, a much more significant thunderstorm occurred over Western Sydney although the core largely missed Auburn. The worst affected areas included Blacktown, Penrith and Richmond. I am aware of marble sized hail at Blacktown, flash flooding being reported around Penrith and Richmond and power loss in some areas from lightning strikes.

The most intense part of the storm occurred over Penrith where 50 mm of rain fell. Box Hill received 43 mm of rain and 34 to 39 mm of rain fell around Blacktown and Baulkham Hills. My two photos are provided below.

At Auburn rainfall was much lower being in the 9 to 13 mm range only because the more intense cells passed to the west or just to the north of the suburb.

Like you Harley, I could only manage a lunch break and had my eye on a particular cell at work wondering what might happen as it interacted with change. Got out barely in time to race out along the M2 and M7.

Got some video of the supercell structure from the M7 and thought I was in the box seat as it tracked NE.  However, the storm/or new updraft rapidly reorganised to the north such that I ended up the wrong side of the inflow bands (last still looking north) and the chase ended pretty soon after with heavy rain and intense CGs near Rouse Hill.

Unfortunately work played a major role in ruining my day.

Thankfully I got a brief consolation prize near the coastal suburb of Warilla( 20kms south of Wollongong) Unfortunately there was too much scud to determine whether this storm was a supercell or not. However it contained big enough hail to suggest a possibility. At one stage I had pure 3-4cm hail(and quite alot of it)  without the slightest hint of rain, and this lasted for a good couple of minutes. Hail turned to heavy rain. I stopped and looked for hail in the pouring rain knowing the hailstones would melt very quickly. This was the biggest I came across, a genuine 5cm stone. Unfortunately I dont have video from todays events, as I stuffed up. I thought I was filming, but it turns out I wasn't . The hail footage would've been rather nice :(



And heres a video from last nights very active lightning show on the far south coast of nsw. Unfortunately the bolts were few and far between,but the cc lightning in front of the sunset was a spectacular scene. I didnt see much structure from this storm either as I arrived too late, but I imagine there wasnt a great deal to it with the radar showing a messy line of storms rather than a discrete storm. It was extremely active though,with  a flash a second at times.

A crazy right moving storm just came through Coffs. I was taking shots of the lighting with a couple of other guys from Coffs and witnessed quite an amazing microburst at around midnight! Was quite a sight to see and hear! I'll upload some photos tomorrow :)

Here's some footage I shot at home of a supercell heading through Cranebrook in Sydney's west tracking NE yesterday afternoon.
It had some quite strong winds with it and hail to about 35mm in diameter.

The Northern Rivers region was largely dudded yesterday (16th) due to storms developing mid to late morning, though activity persisted around and just into the district during the night.

One storm finally passed by quite close and I managed to capture this at 4 AM EDT today (17th). I saw no other lightning that came close to this one, just a pity the highlights blew a bit due to a second pulse.



The bolts are hitting the ground about 6ks away.

Very Nice Michael, tried last night to get a few lightning shots but it just wasn't there for me, just a few CG's but nothing great from Bracken Ridge.

All these storms should fuel up a few tropical lows in the Coral Sea over the next couple of weeks, it is interesting looking at the MSAT water vapour image.           http://www.goes.noaa.gov/sohemi/sohemiloops/shwvgms.html

A few photos of the storm yesterday

Around 11.42 am a nicely structured tower formed.



Some Mammatus cloud at 1.20pm



The following photos are untouched, just trying to highlight how dark it got at around 2.10 pm







The tail end of this cell at 3.14 pm as we waited for the next line of storms to roll in.
