Classic Supercell near Lismore NSW 23 November 2015

Published by:

Classic Supercell

Amazing classic supercell structure today as the first of a series of supercells spread through and menaced central parts of the NSW Northern Rivers district. Hail 6-7cm observed at Ellangowan from this storm.

Simla – Matheson Colorado Tornadoes 4 June 2015

Published by:

Tornado in Colorado

This was the last day of chasing for the 2015 USA trip by Michael Bath, Jason Paterson and Rodney Wallbridge. The initial target is Limon, Colorado.  Moisture seemed better than forecast as we head south from Cheyenne, Wyoming with a strong storm going up behind us to the north, and then the first signs of a storm just south of Denver. Around the eastern outskirts and then SE of Denver this storm had split then consolidated on the southern side, which was our target from the outset. Some brief small hail hit out of the anvil on the interstate. NW of Limon was the first stop to observe the now LP supercell structure.

20150604106

Grunty base with very large anvil, powerful updrafts and some crawler lightning. After a while we moved west but it was the wrong road. Large drops and some small hail so we turned around and headed SE then onto the road to Matheson. More base and structure stops.

20150604219

There are times where two mesocyclones are very apparent. Bases had been high but they were slowly lowering over time. The storm is slowly creeping towards the south. We found a great spot just SW of Silma where the structure evolved into a classic supercell. Bases again lowered on the right and then a very obvious wall cloud suddenly appeared. Not long after a funnel cloud then a slender cone tornado touches down! Awesome, especially with the beautiful contrast and evil looking base. This lasted several minutes before lifting.

20150604237

20150604255

Minutes later a needle tornado touches down and this time we can see the point on the green rolling hills nearby it impacts.

20150604288

The rear flank downdraft (RFD) rain wrap is heading towards us so after the second tornado lifts we move quickly west and south - not far from the first spot. By then another cone tornado with needle has formed. We soon get splattered by some small hail but the scene is incredible and it doesn't matter. This funnel lifts for a short while before dropping again for touchdown number 4.

20150604325

The collar cloud from the mesocyclone is right overhead and the RFD is closing in again so time to move once more. This tornado lifts. By the time we do a short move west a large cone has formed.

20150604345

There are still bits of rain and hail, which get larger with some golf ball sized stones in the mix. From the first tornado occurring the storm starting moving more SE so we now have to move a fair bit west then south to get around into position again (we are west of the storm). We soon spot tornado number six in the distance to the east. It looks like a landspout type from our position but not sure.

20150604392

Dust from the ground gets drawn up into the funnel. Onwards with various east and south jogs. There are two mesos apparent at this time again. We are focusing on the SE one when one to the west drops a brief cone tornado. A massive beaver tail forms with crazy updraft structure but this is about the time the storm begins to dissipate - over 5 hours of enjoyment from it.

20150604481

Meanwhile an LP supercell with barber pole updrafts had gone up to its NW. We watched this into sunset when it rapidly collapsed.

Motel at Limon where a hailstorm hits at about 12.30am. A great way to finish the journey.

Supercell Outbreak NSW Northwest Slopes and Plains 21 March 2015

Supercell Outbreak NSW Northwest Slopes and Plains 21 March 2015 31

It was awesome to have an impressive setup on the weekend for the NW Slopes district of NSW. Michael Bath and Jason Paterson head inland initially targetting the Warialda area. We arrive just in time as congestus begins...

Between Inverell and Warialda at 1.30pm
2015032100

The first storms have developed with splitting supercells the order of the day. Suprisingly both left and right movers remain powerful and long lasting. The following pics are of the first storm and the left mover.
2015032101

Green tinge in the powerful updrafts.

2015032102

2015032103

We let this cell go knowing Jimmy and Colin were onto it.

2015032104

The chase continued back to Warialda then 20km to the northwest to pursue this next supercell. This storm was a right split from initial development halfway between Moree and Boggabilla.

2015032105

2015032106

Some nice structure including inflow features for a while

2015032107

2015032108

Outflow boundaries pushed up a lot of completeing storms shortly after this. We had to punch through torrential rain and very hard 2cm hail to get west for new development south of Moree.

2015032109

Probably the biggest storm complex of the day had now developed - again from a split, the right mover went on to drop giant hail in Narrabri while this HP beast edged towards Moree. The first pics are from approx 40km east of Moree looking SW. The inflow winds were impressive here.

2015032110

2015032111

2015032112

2015032113

Time to dash further west around the core....

2015032114

2015032115

2015032116

Once in Moree outflow boundaries caused cells to go up everywhere. The winds were powerful with some damage well outside the storm core - gusts to 95km/h at Moree Airport and the storm missed! There was plenty of dust and tumbleweeds too!

2015032122

The edge of the supercell is now just to our east but also competing with other new storms.

2015032121

After battling some cluttered storm activity and dust we decided to keep heading NNE up to Boggabilla to try and intercept the storms again east of there. A small storm pops up ahead of us during the drive.

2015032124 2015032125

The earlier supercell had died but a new storm tracked straight at us - topping off the day with an epic lightning show. The inflow winds into this cells were ferocious at times and only collapsed as the precip hit.

2015032126 2015032127 2015032128 2015032130

Last one from inside the car as the bolts got too close for comfort!

2015032133

Then began the 4.5 hour drive back home....

Michael, also enjoying his 48th birthday !
This is the impressive Moree sounding for the pre-storm environment
