After a
couple of days of activity but
with other commitments, I was
finally able to chase today.
The
hallmark of the day seemed to be
low speed shear producing mainly
pulse cells - storms that would
fire up but then die shortly
after. Slow moving storms are
easier to chase if you're in the
right place when they get going,
but travelling some distance to
meet something that looks great
on radar for a while but dies as
you approach is frustrating.
I started
off at Drew's place in Middle
Park and with a cell heading NE
towards Logan, we headed E along
to the Logan Mwy. Around Forest
Lake, we got lucky and, even
though it wasn't particularly
severe, we saw probably the best
development of this storm. Plenty
of CGs landed ahead of it
providing a nice show for us,
including a couple of close ones
that landed behind us! Here's the
RFB (rain free base) as it
developed:
As the rain
started falling at our location
we took off north and stopped at
Archefield airport. There was
little cloud structure, but still
plenty of great CGs. Another one
landed within 50m behind us!
It looked
to be weakening further, but we
decided to stay ahead of it in
case it fired up again.
And ended
up at Mt Coot-tha. The lightning
was over, but the rain provided
an interesting view of Brisbane.
A new cell
was now heading north towards
Marburg. We didn't want to chase
from behind so our only other
option was to head up the Mt Nebo
Rd to Wivenhoe dam, then head
south to meet it. Of course, this
plan would only work if the storm
could last the distance.
Unfortunately, it didn't. So, 15
minutes up the Mt Nebo Rd, we
turned around and headed south
towards the Boonah area for some
new small cells that were
forming.
Again, the
'pulsey' nature of these storms
meant that everything had pretty
much died when we got to Boonah.
So we hung around for a bit,
hearing a few final rumbles of
thunder, and watched the rather
gorgeous sunset. It was hoped
that something would fire up
after dark so we could shoot some
lightning, but it was not to be.
Not a huge
day but still great to be out and
about!
