The numbers
always looked good for today, but
I think those who chased a little
further away from Brisbane were
rewarded for it. Without the
forecasting knowledge of some
chasers, I tend to play things a
little safe, not venturing too
far without some solid activity
occuring. The obvious downside is
that I usually miss anything
further away.
Even before
midday, healthy cells were firing
around Tenterfield and
Stanthorpe. Shortly after, stuff
started popping up north of
Toowoomba, so I sat around
wondering which area I should
target. The SW cells had
progressed NE to Warwick and
Killarney. Hoping they would
continue I finally took off for
Boonah. Here's what I found when
I got there at 3:30pm:
Radar
at 3:42pm
Armed with a fancy new intervalometer (timer cable release) I shot some timelapse footage of this cell. This sequence runs from 3:40pm - 4:30pm, and for the number nuts comprises 942 exposures of 1/100s @ F7.1 for the first part, and 1/40s @ F7.1 for the second part (100 ISO) with a time interval between shots of 3s.
By 4:30pm
activity was becoming more
widespread:
Radar
at 4:30pm
Lightning
activity was pretty frequent as
the northern end of these cells
developed and moved east towards
me.
The regular
CGs and embedded lightning in
front were interupted
occasionally by bright
intra-cloud lightning directly
above:
At 6:30pm
rain forced me north to Peak
Crossing where the lightning
frequency increased dramatically!
This line of storms was
flickering constantly, but the
huge positive stroke I was hoping
for, and expecting, never
happened.
Radar
at 6:54pm
It didn't
take long for this now extended
line to start dropping light rain
so I took off, hoping to head
east and stay ahead of it.
Without radar I had no idea what
was happening and was surprised
to hit heavy rain even before the
turn-off east, suggesting that
activity was bending around to
the NE.
All I could
do was floor it and hope to get
ahead of it. Having not scored
any close CGs so far, I decided
to set the camera to continuous
shooting (2s exposures @ F9) and
wish for the best while driving.
Unbelieveably!:
With this
now healthy line looking like it
was heading directly east, I met up with good friend Drew at Wellington Pt.
Here's a
100% crop of the last image which
seems to show the towers on Mt
Coot-tha being struck!
Another
possible hit of the Mt Coot-tha
towers!:
Now with radar access, we discovered that our
east-moving line was now sliding
SE. We considered heading south
but realised there was little
point with rain likely beating us
to any spot. So we stayed put and
were rewarded with some localised
activity which had sprung up.
At 9:45pm
with all lightning activity
appearing from the south, we
decided to head to a sheltered
spot at Rochedale. After half an
hour of nothing in this new
location, it seemed like it was
all over red rover with all
lightning activity well out to
sea, when a new small cell
magically appeared over Brisbane
airport, giving us some great
forks which made the hanging
around worthwhile.
Radar
at 10:30pm
We
eventually finished up around
11pm.

Great shots Marty. I was thinking last night that you'd be out having a field day with the first real good storms of the season.
Keep up the good work

Wow
Amazing pictures/video, my favourite picture (hard to pick) would be the 3rd last one, looks like a powerline or something, all zig zaggy.
6/5 for all pictures and video.

Mmmmmmmmmm timelapsssssssssssssssssssss....
That time lapse is a veritable winner. Can't wait to see one of an incus forming and spitting!

All of your pictures are so beautiful Marty. Love the video.

I think you've got yourself a very nice timelapse of a supercell during the first 20 secs there Marty...I think I can see multiple sources of inflow (mainly from the left, plus a bit from the right going into the storm a little higher) plus a lovely persistently rotating updraft smack bang in the middle!
You wouldn't have been at the famous One Tree Hill lookout would you? Going by radar and the timelapse I reckon the storm would've looked just like that at that very spot!
