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.


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.


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.



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


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.


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.


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.


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.


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

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.

Green tinge in the powerful updrafts.



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


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.



Some nice structure including inflow features for a while



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.


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.





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




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!

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


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.

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.

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


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
