Tornadoes and Supercells Storm Chase 2016

Published by:

Lightning and sculptured supercell

After 3 years, another opportunity for storm chasing 2016. The following Youtube videos and extensive selection of the most important images from this year's two week chases are included. This includes timelapse videos of rotating storms and spectacular lightning - some of my best lightning shots!

With a period of significant high CAPE and south west flow predicted, it set the scene for chaseable supercells and tornadoes. The following are a gallery of the storms and tornadoes from the 2016 storm chasing in Tornado Alley - namely, Texas, Kansas and Oklahoma. This was the first storm chase. After a frustrating storm chase with merging supercells, increased moisture and an outflow boundary, the Perryton, Texas storm finally comes tornado warned. Turn onto the road west and there it was! Cone tornado. Too dark for immediate shots and I finally was able to get footage and shots on tripod. It wedges out and then surprise another circulation produces a separate simultaneous tornado. After examining the inflow notch a couple of times a third funnel cloud and possible tornado occurs.

The next day, after a brief supercell near Clarendon, Texas, I ventured further south for tail end charlie. Unfortunately, there were several supercells spawning near Plainview. I simply decided to wait. Radar then suggested nice structure it seemed to my east. But where was this storm - there were so many storms. Finally I realised it was the on producing lightning just to my east. This became the Turkey supercell! It produced a likely wall cloud but the updraft and the storm structure improved to a beautiful sculptured LP supercell! Sunset illuminating the updraft and vault clearly defined! With lightning threatening to singe the earth, I took note that the base had begun to show a bowl lowering. The storm eventually became tornado warned after dark and produced a cone shaped tornado and wedge tornado soon after (chasers suggesting the same damage path).

The Dodge City tornadic event stunned me: despite the favourable tornadic conditions for strong to violent tornadoes, I did not anticipate such a prolific event. But when two mesocyclones developed side by side I thought a cyclic event was in order. 20160524jd088 20160524jd090The way the first tornado roped out and reformed just as quick and became strong to violent is something I had not witnessed prior. Multiple tornadoes at once was simply insane. A flood of tornadoes - one set 3 at a time and another 3 twins! Intense vorticies formed under the front mesocyclone dancing around each other.20160524jd098 20160524jd101

 

 

 

Travelling through Dodge City with sirens blazing and tornado on the west side of town made for some intense chasing - street by street! Finally out the other side and again another tornado spins to the earth and takes out a house (unfortunately a negative part of the event). The power flash followed by debris spinning around the vortex certainly demonstrated the power of what seemed such a small tornado.20160524jd108 20160524jd110

 

 

Finally one more tornado seemed to developed further north and the storm had run its course! Some counts suggest based on the true definition of tornadoes that 8 to 10 tornadoes had been spawned from this event!

Rain events South East Australia August 22 to 25 2016

Weather models are presently suggesting a rain event to unfurl across a large portion of south east Australia over coming days.

When analysed, it appears that this will occur in two bursts with the first one passing across northern New South Wales and southern Queensland during Monday / Tuesday with the second one passing through New South Wales, Queensland and north east Victoria during Wednesday.

The second event appears to be more substantial in which an inland low will develop across Queensland and New South Wales then cross the coast near Sydney before tracking south east then moving away as an east coast low.

Combined, the two events are expected to deliver healthy rainfalls across North East New South Wales where 30 to 120 mm could potentially fall.

The development of an east coast low south of Sydney appears interesting as there is potential for falls upwards of 120 mm within an area from Wollongong to Ulludulla on the New South Wales south coast and Illawarra region.

Models are likely to vary again as the system develops but it is one system to watch with interest.

The attached satellite photo (Himawarri) and dated 21 August 2016 is showing the development of the cloud mass that forms the weather system to pass through south east Australia in coming days. A feature of this is that there were thunderstorm activity across the Alice Springs region Sunday morning. The cloud mass seen will build further as it tracks further east and influence the weather in coming days.

Heavy rain event New South Wales 1 to 4 August 2016

During the first week of August 2016, a strong rain event crossed through much of New South Wales delivering significant rainfalls across some areas of the state.

Early in the week, the system passed through Southern New South Wales and North East Victoria producing some localised flooding around the town of Wangaratta. While only 29 mm fell around town, the combination of heavier rainfall across the highland areas to the south east and coupled with a wet May to July period, the event was enough to cause some flooding near and within town.

Albury Airport had 24.8 mm, Rutherglen 27.6 mm, Dartmouth had 37 mm and Hunters Hill had 38 mm. The rain was mainly light to steady rain of long duration.

As the system crossed through New South Wales and the coast, a more significant drenching occurred across some areas. During Tuesday, Oberon had 41.5 mm Orange had 43.6 mm, Bathurst 44.8 mm and Armidale had 49.8 mm.

As the system passed through Sydney, some northern suburban areas received significant falls. For the 24 hours to 9 am 4/8/16, 61 mm fell at Observatory Hill and 63 mm fell at Chatswood. For the same period, a weather station at Strathfield received 90 mm being the highest for Sydney.

As the system crossed the coast and developed into an east coast low, some very heavy rainfall occurred on the New South Wales Mid North Coast and around Coffs Harbour.

The heaviest falls from the event fell around Coffs Harbour and the hills to the west. Meldrum to the west of Coffs Harbour was swamped with 239 mm followed by 214 mm at Middle Boambee. Bellingen had 167 mm and Woolgoolga had 161 mm.

This turned out to be a significant rain event for August across some areas of the state as shown. The rainfall plots from the Bureau of MeteorologyWater and the Land” are provided showing where the heaviest falls fell during the event.

Cold winter period SE Australia June 20 to July 13 2016

During the last 10 days of June and the first 9 days of July 2016, winter has taken hold across south east Australia. A succession of cold fronts has brought gales, rain, and snow to low levels across Tasmania, Victoria and New South Wales.

Now another system is bearing down across the south east for Sunday to Tuesday that is expected to bring low level snowfall possibly as low as 500 metres in elevation by Tuesday to the the higher elevations of Victoria. Forecasts of snow as low as 700 metres are being made for certain areas of New South Wales such as the higher areas of the South West Slopes and Central Tablelands during Tuesday.

Over the past few weeks, the ski resorts of South East Australia have enjoyed significant snow falls with snow depths now varying from 50 to 80 cm with Mt Buller having a maximum depth of 80 cm where snow making is occurring.

There have also been snow across the Central Tablelands and light falls into the Northern Tablelands to places such as Guyra.

During the period June 24 to June 27, a more significant cold outbreak occurred across the inland of the south east with maximum temperatures struggling to reach 10C across many centres such as:-

1 - Albury 26/6/16 - A minimum temperature of minus 1.3C and a maximum temperature of 7.5C.
2 - Bathurst 27/6/16 - A maximum temperature of 6.2C.
3 - Cooma - There were 3 days of in a row where the maximum daytime temperature failed to reach 9C.
4 - Oberon (24 to 29 June) The maximum temperature failed to reach 7C on 5 consecutive days with the coldest being 1.9C on June 25.
5 - Orange 25/6/16 - The maximum daytime temperature reached 3.1C.

Even in Western Sydney, there have been bursts of cold such as what occurred on June 27 where maximum temperatures struggled to reach 12C or 13C.

In Sydney (Observatory Hill) the maximum temperature reached just 11.7C on the 27/6/16. Such low maximum daily temperatures for Sydney City are rare.

As shown in the attached satellite photo of Southern Australia 9 July 2016, the next winter cold front will be significant as it crosses the southern part of the continent. It is projected to produce gales, cold weather thunderstorms, local hail and low level snowfall to a large region of the south during the early part of the new week.

Coastal New South Wales will be spared the worst of this system.

Certainly in Victoria, warnings are already issued for damaging winds of up to 90 km/h across elevated parts of the state (NE Victoria) as well as low level snow falls once the system passes through.

The attached satellite images show the cloud mass ahead and with the next winter front as it passes across the south that will produce a cold outbreak in coming days.
