After several days of rain, the ample moisture and nice SE change gave some nice storms in inland SE QLD including a nice rotating cell!

After several days of rain it was a change to wake up to sunny skies.  We had a westerly change push through the day before giving a severe squall line through SE Queensland, although it was largely featureless from when I saw it although it gained some nice features closer to the coast.  If nothing else, it cleared to give a lovely sunset which was quite nice!!!

On Sunday I had to fill in for some one at work – the odd thing was if I had chased I probably would have targeted the downs rather than my own area.  If I had down that I would have busted, and missed out on a nice storm that went right over my house!  In the morning I decided to do some bushwalking around the Moogerah Peaks area, on top of Spicers Gap there was some nice Cu but it was mostly small.  I started work early in the afternoon so headed back home.  During work there were some nice larger CJs, but nothing substantial.

Eventually a storm developed to my south – it became quite large very quickly and soon was giving thunder every 5 seconds or so!

I thought the storm was going to go just to my east, and I had just finished submitting anything so decided to chase.  I had only made it about 1km from my house though when I had to come to a stop to take some photos.  The inflow band was quite nice on the right, flowing into what appeared to be a nicely rounded and striated updraft base.

I waited a little longer watching the storm come to me – some deep lowerings developed underneath the base, but they looked outflowish – however they weren’t, they were flowing into the base and the outflow region was well off to the east producing a nice gustfront.

I had gusty NE’ly winds up to 20 knots, sometimes pushing 25 knots (winds were increasing as the storm approached), in the meantime a 20-25 knot SE’ly was pushing behind it which was allowing the storm to become more structured and interesting than it normally would in a weakly sheared environment (apart from the low level shear being nice!)

AC

I ended up moving another kilometer before taking some more snaps as it was impossible to keep driving constantly looking in the rear vision mirror with the awesome site behind you!

I then headed off to Calvert, the storm looked nice and was slowly rotating with two large inflow tails feeding into the main updraft. 

One thing that did catch my eye was a long, needle like funnel that appeared to rapidly descend to the ground in the semi-distance. 

This was more interesting than the other “wedge like lowerings” because I could see the movement in it was quite strong (upward motion very pronounced), and the way it both developed and dissipated was extremely rapid!  It lasted for around a minute, but too far to see rotation or debris and the hill doesn’t help either…

Unfortunately the storm was moving slowly and the outflow looked to eventually cut the inflow off and the storm began to become quite outflow dominated and eventually weakened.  I ended up following the gustfront into Brisbane, but it certainly wasn’t as spectacular as it was before although still pulled over on the M4/M5 junction to grab a snapshot!

Still, quite a nice and interesting chase - it was a nice ending to what had been a nice run of 8 or 9 thuderdays in our area...and I got back in time for a roast pork dinner!  All while enjoying a nice sunset as more storms developed on the ranges...






Neil Pennel who lives in the Kalbar-Warrill View region was kind enough to email me some reports of this storm!  Neil received 60mm in 40mins while his neighbour 2km away recorded a whopping 125mm in 40mins!  There was also some strong winds reported with a tree (3ft diameter base) snapped at the base!

Neil took some photos afterwards and has given me permission to add them to this report and are below:
