Just S of Ipswich was the first port of call today. 100 knot upper level winds were blowing the cloud tops way ahead of the storms but also producing some lovely mammatus. This is just near Peak's Crossing facing east-ish away from the storm underneath the anvil:
And back facing W towards the storm as it died:
Cells were also developing SW of Boonah:
A quick drive to Boonah yielded a much better view. A guster was forming as the cell turned black on the rain radar!
suspect lowerings were worth
keeping an eye on. I thought I
detected rotation at one point
and this storm was later declared
a supercell. A supercell is a
storm with a persistent rotating
updraft which can spawn
was now heading for Beaudesert. I
didn't want to stay directly
ahead of it because that's where
the rain was falling so I decided
to just follow it.
arrived at Beaudesert and with no
roads NE (where the storm was
going) I chose to head N up the
Mt Lindsay Hwy. A fatal accident
just N of town (apparently caused
by hail from this storm) forced a
u-turn - and then 200m back from
where I came, another accident
had occured and I was forced up a
side street into what felt like
the wilderness of the Gold Coast
hinterland. Trying to get out of
there and hitting too many
dead-ends attempting a short cut
to the storm meant that it well
and truly out-ran me. It was
constantly flickering away with
lightning as it got dark and I
saw some sensational bolts, but
unfortunely I never got to a
survived well out to sea.
