Original title: I have to post these first so I can post them second.
I was having trouble with the computer. …
Whilst I was enjoying myself playing the fool on here last Saturday, there was adequate waring that things were going to get bad in the USA.
If you have ever seen the film Twister, the hero in the film says something about the sky greening up. Of course that was just a fil and all the action ended up happy ever after.
But the sky does gren up before thunder. With snow too it blues. A lenticular refracts the light in such a way. Above the cloud the silver lining might be mirroring a rainbow. But only the warning light gets through.
Over the Atlantic a warning is flashed in time for people to become aware of a potential danger. ANd that is all you need if you are wise.
The first is North America before the event. Fairly good weather all around:
This is what to look for: First check the UK MetOffice's North Atlantic chart. And if you can see a Low is moving between two Highs, that is the signal. The Low will drop 5 millibars before it crosses the Mid Atlantic Ridge and 24 hours later there will be storm reports:
Typically when a disaster occurs my computer or in this case the library's computer plays the damn fool. So I hope one of these pictures is OK.
There were a couple or three bad days. I never looked and got the N.Altantic charts first. I'll get a few more after I post this edit and paste them in here or in the comments below if it seems better to do that.
