What Causes Derechos

I think I know but I have an habit of jumping to conclusions so I asked my God for help. Now here it is:

The analysis chart is showing volcanic break up typical of Complex Lows except that this is a Complex High. Wait and see what the fools do with the science rather than accept that a dullard like me lead the way. Yes I know they can wait me out. They can watch until I die, it can’t be that long before I go.

I think this might be it:

I said Tuesday on Reddit just now meaning Tuesday afternoon but now I think it’s more like Monday.

Edit: And now it is Tuesday and no derecho, got rain though so at least it rhymes. There is a lot to be said for staying in when your shoes leak on days like this.

When elongation takes place in a cyclone it inevitably occurs as anothe volcano joins the melee producing in the NorthAtlantic charts the phenomenon of a dua. That is another fuel source for the atmosphere. With this elongated high: H-1030 there does not appear to be a suitable volcanic eruption, at least nor since:

Marapi (Western Sumatra, Indonesia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 .
The full report is as follows: VA TO FL200 LAST REPORTED AT 02/0450Z OBS VA DTG:02/1150Z to 20000 ft (6100 m)

Dukono (Halmahera): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 8000 ft (2400 m) altitude or flight level 080 and is moving at 05 kts in N direction.
The full report is as follows: VA TO FL080 OBS AT 02/1640Z EXT NNW EST VA DTG:02/1640Z to 8000 ft (2400 m)

on the 2nd June. Which makes one wonder if anyone in Meteorology had any reason to expect their model to know.

Moreover the output of Central and South American volcanoes especially Sabancaya was profuse, how was the chart not affected. Or was it?

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 25000 ft (7600 m) altitude or flight level 250 and is moving at 10 kts in NE direction.
The full report is as follows: INTERMITTENT EMISSIONS to 25000 ft (7600 m)

Is Low-974 between Greenland and Norway the volcano Sabancaya. Well, well… that would be strange. Why didn’t I consider that ages ago?

When you are not working with Jehovah it could mean you are working against him. Time to go for a walk. I have been a dope!

And Ibu is back. I wonder if this explains the tornadoes. Hang on this is a three day delay. Damn when did this happen last time?

I must learn to expect these. Better still find out what is behind them. You can’t expect to expect things you don’t expect. And now I have to wait for them to release the evening charts.
