Several years ago, while friends of mine were happily married -or at least still comfortable with each other, I was sitting itn the back of their car and complaining about my leg. What drew their attention to me moaning was that I was saying that it seemed to have grown more muscular than the right leg. So they took me to hospital. I was made to wear one of those stupid smocks that show everyone your worst visage.
Led into a room I was given a nice white blanket-comforter and made comfortable with it, on a bed. A doctor eventually told me I had deep vein thrombosis and I stayed with him instead of them.
For a week.
A week in bed allowed my veins to show through the skin of the ankle involved a subject of little or no interest to the woman that saw me at Out-patients Clinic. But she gave me a prescription for some thick nylon stockings without telling me they would hurt like hell if I wore them without shaving my legs. It took me painful weeks to stop wearing them and just get on with my death.
I am not doing too badly with that am I?
Except for not being able to fit into comfortable shoes...
Somewhere along the way I developed gout and had to find wide fitting shoes (Tuskers are about the best, if you are similarly afflicted.) Recently, they began treating me for the gout and it had affected my shoe sizes again, with the result I could still wear the shoes but with thick, winter socks. So they became the preserve of snowy weather; all three pair of exceptionally hard wearing work shoes.
I tried them out one summer and noticed that my feet seemed sticky in them. The shoes had developed an uncompromising method of staying put in resisance to me walking.
Like one does on these occasions, I realised that the tongue needed a packer on it, so I obliged with a pair of rawlplug strips. For the life of me I can't think why I bothered; except that in retirement I couldn't see the buggers ever wearing out and I did need a new pair of shoes at the time.
This all came to an end outside a real estate agent's shop window at the top of Hartshill in Stoke on Trent, one afternoon.
The rawlplugs had worked loose and my size elevens no longer fitted my dainty number nines. Suddenly the pavement appeared and I just realised it in time to try an head dive out of its way. I failed but tackled it mightily (for an old man) and lay there counting the cost of looking stupid rather than better shod. Bloodied and bowed I got up with relatively little damage, to find a coterie of women gathered to admire the fallen hero.
I think women like to see bleeding men but I felt foolish rather than heroic and just wanted to slink away. It was not to be. I was invited into the estate agents to sit for a minute and realised that my youth had gone and with it my attractiveness to women.
Ah well; I do have big feet after all (actually they are size tens -only “size nines” sounded more dramatic.)
My problem with big feet also shows up on Usenet. A forum on which I am suspect, obviously, due to my lack of expert training and big feet. Watch:
A recent comment reminded me of the above -and the group (a writing club that meets at Clayton Library) is taking in stories today, so…
There is a lot of technical jargon in this, so bear with me. I don't really know what any of it means but it is raw expertise and well worth the effort of letting it wash over you. (At least it is if you have pretensions of earth scientism.)

It would be interesting to get an explanation (from our resident panel of experts!) on how a vigorous low - that seemlingy comes out of nowhere – it develops over the SW in the next day or so?
Is it some kind of wave on the cold front that seems to coincide with an upper cold trough that you can see at about 15°W at 18 UTC this evening?
The other thing that has me wondering is the rapid change of type from cyclonic to anticyclonic easterly in the next week (if it comes off), it almost seems that this rapid cyclogenesis is the catalyst for that

N. Cook:
Still not fully emerged on Meteocentre Near Real Time synoptic, lack of barometric monitoring in that area?
If the 1012mb loop becomes the low then it would now seem to [be] farther south and not crossing Ireland as per MetO latest synoptics.
[He's interested in storm surges, so I talk to him a lot even though he can't -or won't comprehend me. "mb" refers to the air pressure in millibars.]

Will Hand to the OP:
It looks like classic "left exit" of a jet cyclogenesis to me. [The] Worry at present is that the low will slow down more as it deepens, meaning more prolonged rain and snow in the west.
[Cyclogenesis is expertise for Gathering Storm.
This expert had once promised me some data on Blocking Highs but I managed to sort them out without the promised help. I don't believe he ever found out what their cause is (to his own satisfaction) nor does he believe me mine (I expect.)
I have no idea what a “left exit” is. All storms move right (west-north-west) or “block” the Atlantic with a long-standing wave. Ah, I have just realised he meant it was going backwards. They do that with volcanic eruptions -especially eruptions at Reunion in the South Atlantic.]

Ain't you watching the deep one?
No, nooo... You can't possibly mean that 982 at T+84!
[I'm looking at the Met Office Sea Level charts, the only ones I can understand. There is a Low to the south west at the end of that page's forecast (84 hours off.)]

Have you been reading my posts again?
You'll be sorry.
[I had discovered that when two or three lows run close together they bring in an high, a reaction to the laws of motion. There is a post about it on that forum studiously ignored by experts :)]
Actually it looks more like the this: http://www.spc.noaa.gov/climo/ for that. [A chart showing some wind on the Great Plains]
The thing is that I am prepared to be wrong, why is no one prepared when I am right?
Is it the way I tell them?
Well...expletive deleted! [You see why?]

You are right about the sinister escapement. Normally (if he means the 948 mb on the tip of Greenland) that low would fill the sea between that hook and Norway (Soerheim country, not sawhim in a while. Must be all that lack of snow.)
[Bjorn Soerheim is a regular poster when there is a lot of snow. We first met in December 2004 just before that Tsunami.]
However that cyclone seems to be wrapped around Greenland into the Davies Straight and thus it is not a blocking low indicative of a tropical storm so much as cyclogenesis from the removal of volcanic activititious kind. (You can tell from the shape of the front it subtends -a delta.)
[So that is what a Left Ext means what a stupid name; who invents those?]
It are going to be a Line Storm. [Also called Derecho or Bow Wave]
It's either that or burning socks, making up some more carbondioxide, imagine where the sulphur is coming from -or rather not, as the case may be.
[Recently I have been poking jibes at a really stupid troll who keeps pasting links to Global Warming (a theory invented by Margaret Thatcher to kill Arthur Scargil in return for his getting industrial illness compensation for coal miner and forcing her to close all our coal mines.)
The troll will not believe the concept of Global Warming is dead and every chance he gets, there is a thread about it. I would be able to ignore those, if it wasn't for the fact he has invented fictional characters to praise himself and keep the threads above water.
And does it all badly! (That was another jibe at him. I keep saying that I would like to be nice but never try to be. At least I don't try very hard to e nice. But I don't need to try all that hard to be honest :) ]

Their absence means that I am the one replying here; in this case to the third poster in this thread, the poster is one I have a very great deal of respect for. I actually respect the others too but not so much that I can refrain from chiding them for being “scientists”. I don't have a great deal of respect, for most scientists- their words usually come in quotes from journalists that say “Scientists Say:...” and the journalist goes on to deeply annoy me.]

The charts depicting the surface pressures will be appearing on my blog if you are interested in trying to understand what I was on about. I am just vaguely starting to understand what Will Hand was saying but the rest of it from Bernard Burton is lost to me. But I can appreciate great learning for what that is worth (it failed to mention anything about bad weather in North America as far as I can tell, so you can make your own mind up about it's values.)
You can work out what a derechos costs from the insurance claims when they get reported -if they get reported. (Usually in newspapers and broadsheet-websites they will be included in seasonal stuff.) This bow wave is, at best, a minimal derecho as it has so few tornadoes on it. The whoppers we had recently (23rd and 24th February 2016) drown that one above with the data on them:
The damage from these causes £-billions. I forecast them from the same sort of charts that were discussed above. There is no reason that anyone can't do it (even the experts charged with forecasting them) if they wanted to. The forces involved are far too powerful to allow any serious attempt to prevent damage to property but with at least 84 hours advanced warning (A 10 day forecast might be prepared if the powers that be were capable of running a tight ship and making people in high places do the right things.)
Unless something more interesting crops up, I will show you what to look for in my next thread here.

Following some of the comments from the writing group earlier today the consensus that most of the words were too big for use in regular entertainment. It occurred to me that some folklore might relive the stress of having to grab a little educational material so late in life, that the average person might prefer to learn how the planet rotates in baby talk. It seems daft to me especially when the experts have doe there best to provide us with nicely coloured pictures.
They are the nearest thing to cartoon strips one gets, in science.. Perhaps it is better to keep such stuff on its own thread. Pity that It has to be on this place, I have just discovered that there is o power of editing on here.
After struggling for hours trying to get an account with Webs, I realise that I no longer want one that is so hard to get. How does one go about getting free web-hosting these days?
