https://youtu.be/5YFUDj2XRLE Just a few of the supercells that roamed across Sydney on the 20th December 2018. This produced an unprecedented event where numerous supercells developed in extreme CAPE (by Australian standards). Unfortunately, storm chasing in Sydney is near impossible but I made the most of what I could in particularly the cool timelapse of one of the supercells that developed the developing Central Coast supercell
Had to get out there - almost was not able to! Planned to re-fuel and have lunch at Narromine! It seemed very little food choices in town these days? Has the drought taken its toll on smaller country towns?
Just out of town, commented to Nick Moir about my disappointment of lower than anticipated dew points. The storms had just popped up after 2pm in a line near Nyngan. I was in no hurry to get out there at this point as the storm was racing my way parallel to the highway. There was another complex of cells SW of Trangie so I relocated to Trangie. The cell near Nyngan showed initial signs of updrafts but as I watched for 20 minutes, pulsating bolts could be seen flinging out from the side of the updrafts. A boundary tightened up near Nyngan and radar showed the cell making a slight deviant move shortly after. So I headed WNW to Nevertire. The cell began to explode!
A railway crossing 5km ESE of Nevertire became my viewing point! A green tinge emerged from what was to become a vault. Scanning the scene, is that it or what? A detached beaver tail! Absolutely! - time to time-lapse! My pessimism had given way to overwhelming adrenalin. The beaver tail in classic style becomes visibly attached to the main updraft with what seemed to be a vault and inflow notch visible. Lightning strobed out of the base and in time - powerful lightning bolts intersected the field between myself and the storm. This made myself nervous about safety but simply in awe, just a little bit longer! Every staccato that cut in front of view put a smile on my face. But the storm and lightning were getting nearer.
Then flash and Bang! A bolt descends from the anvil too close for comfort. The storm was warning me so I stopped the timelapse and retreated to the vehicle. Contemplating whether to take the road from Nevertire to Warren Road or head back to Trangie and NE from there to intercept the cell. Trangie won out. Bolts were observed on the horizon and they were nearing at an increasing pace. The storm had begun to lost its structure - other cells interfering with it. On approach to Collie, an increase in the number of bolts provided an opportunity to take pictures of lightning and shelf cloud! Despite its weak appearance, the storm still produced frequent lightning pulsating bolts - some rather close!
All I can say we almost did not chase today but last day of the trip for 2018, we gave it a go with a 7 hour drive. Arrived near Lincoln Nebraska had a coffee and watched as a large cumulus rapidly developed just to our east. After a close shave with hail we manoeuvred our way to the southern side.
I was astonished to see a wall cloud nearby. Finally in position, things ramped up rapidly. From wall cloud to rapid rotation then tornado siren then funnel cloud!. Someone reported a tornado on the river from this. We could not see this!
The storm maintained a couple of wall clouds and continued to threaten tornadoes. This occurred at least 2 or 3 times. The main large wall cloud maintained for at least an hour. It looked at one stage that the storm was going outflow dominant. We were about to leave and under the very low base alas rotation - followed by multi-vortices! Perhaps weak but still very impressive behaviour! This behaviour lasted about a minute but it may have been visible behind the rain from a different angle based on other chasers perspective!
What a day!! It was a high contrast heaven complete with low bases, dynamic supercell and beautiful wall cloud and structure! Then the storm lined out rapidly and we were in fill retreat south to get west as we have to leave Denver tomorrow!
Low and behold who was in front of us on the way south to Kansas - Jane ONeill, Clyve Herbert and team! So we had steak together!
Tornado was on video - either video stills or picture from Fredrick Muscat!
By the way I believe that the two separate reported tornadoes where from different mesocyclones.
Can anyone confirm this with dropper radar please?
Fredrick saw a power flash few minutes prior the tornado as well just north of the road.
Ok this was the SE Nebraska 11th June tornadic supercell. This was the last tornado phase with pencil tornado behaviour. Of course, I had my wide angle lens on being caught by surprise. We were very close to the tornado though so you can still see the behaviour! Best to view in full screen - HD as well. Contrast is enhanced somewhat to show the behaviour. ( there were request from those who were further away seeing a wedge - this proves otherwise!) By the way ignore my violent rotation comment - it was strong rotation but it is 2018 after all! This was believe it or not the first mesocyclonic tornado for Fredrick Muscat
