Lightning Active Thunderstorms Develop Through the Northern Rivers: Monday 13th February 2006 Report compiled by Dave Ellem and Michael Bath |
A storm chase in
the Clarence Valley region the previous day had been fruitless, however better
shear, moisture and instability provided hope for something more substantial this
day. The chase started around 2pm, with Michael Bath and Rodney Wallbridge heading
to Parrots Nest, where visiting chasers Anthony Cornelius and Bryan Juni, along
with myself, would soon meet up with them. With the trigger too far west, storms
were taking their time getting organised, so we setup camp and waited, with several
trips into Lismore to buy frozen Cokes, Pringles and Valentines Day cards!
Eventually storms started heading towards Grafton, so we shot down S and stopped
at a spot S of Maclean. We were treated to a developing cell to our NW with some
nice pileus, while a weak storm tracking up past Grafton managed to produce a
tiny shelf cloud, along with a bit of mammatus overhead.
The cell to our S put out a few nice CGs and great anvil crawlers while we watched,
hoping it would reorganise!
But it wasn't to be, with the cell eventually collapsing totally. As it got dark,
we decided to head back to a spot near Woodburn with the intention of getting
some lightning photos, as a long line of cells was developing and slowly tracking
N to NE through the Northern Rivers. We setup our cameras near Woodburn, however
it soon became clear that the ratio of CG lightning to in cloud CC lightning was
probably 1:1000! Despite the poor number of visible CGs, we still managed to capture
the very occasional nice lightning bolt.
We watched the show for quite sometime before heading back towards home via Evans
Head, hoping to grab some lightning reflecting over the river at Evans. As we
pulled up, another man was there taking photos of the lightning over the river,
and commented when he saw us setting up that he was glad he wasn't the only one
who was mad!
Not long after we arrived, outflow from a cell that was to our W killed the storm
that was moving N up the coastal fringe. Lightning did seem to persist, with some
brilliant CGs and anvil crawlers illuminating the surrounds like day, however
a blanket of low cloud and drizzle prompted us to call it quits around 10.15pm.
Perhaps not quite as exciting as we had hoped the day would be, but it was still
a very enjoyable time and a great opportunity to catch up with some of the chasers
from SE QLD!
