"% Chance of rain"

Pillock.

You sound like a religious nut. You think it can kill you only because people have told you. Try it for yourself. The alleged timing is, fall into ice water and die of cold in 15 minutes. Do what I do, go swimming in winter in a partially frozen lake, and do so for a lot more than 15 minutes. Jesus Christ your teeth don't even start chattering until about 30 minutes.

I think you are disrespecting pillocks

Yes, those are more helpful. But "20% chance of rain" means nothing,

If there's only a % number it should be expressed as a percentage of pouring all day.

All of it.

A superior one.

But is 50% pouring all morning and dry all afternoon or alternating between pouring and dry every hour?

The weather app that I use on my phone gives me a percentage chance of rain for each hour of the day and a symbol next to it for bright sunshine, partial sunshine, overcast, light rain, heavy rain, downpour or thunderstorm.

Years ago I was outside working on my car when a wagon pulled up to collect a neighbour's car. The road is narrow and nothing could get through while is was there. At that point a woman stopped her car alongside mine, got out and asked if I'd reverse her car for her because she couldn't do it for the distance required. She looked a bit panicky when I reversed it at speed for the whole length of the road.

Weather forcecasts these days are the output of models. So it's the 50% probability of the model being right. The further into the future the forecast, the less its predictability; after the event you can assess the accuracy and, based on that, estimate the accuracy of future forecasts. So 50% chance of rain = don't know, maybe yes maybe no. 95% if it doesn't it's a freak, 5% if it does it's a freak.

Could be either, but those two are more similar than a 50% chance that it might give light showers for 10 minutes at some point during the day, which is what the current system allows for.

Ooooh! Snob! An app on one's phone eh? I run applications on my computer. I use my telephone for making telephone calls.

Yeah right, we haven't invented forecasting that accurate. I'll stick to my barometer watch. It draws a graph of the next 12 hours, simply stating it'll get worse, a lot worse, better, a lot better, etc. Stick my head out the window, cloudy, graph says better later, I know the sun will come out. Graph says worse later, I know it'll rain.

I like reversing fast too. I was once told off by someone for reversing a Vauxhall Corsa at full revs along his street instead of driving to the end to do a 3 point turn after the huge line of parked cars. I pointed out that my vehicle was unable to break the speed limit in reverse, so he had f*ck all chance of getting me into s*it by the police. The police never contacted me.

You should go to the highlands of Scotland. Single track roads with passing places. Encounter another car, flash your lights to say you're letting them go first, then reverse as fast as possible to the last passing place. Except if it's a bus then you make them reverse.

Er no. The outoput of the model shows a 50% chance of...

The model is always rght.

The BBC on-line forecasts are effectively useless, since they change all the time up to the moment you realise they are, in fact, wrong.

Well huge, you finally have made an intelligent succint and extremely witty statement.

eople have told you. Try it for yourself. The alleged timing is, fall int o ice water and die of cold in 15 minutes. Do what I do, go swimming in wi nter in a partially frozen lake, and do so for a lot more than 15 minutes. Jesus Christ your teeth don't even start chattering until about 30 minutes .

You still haven't proved it though. But why do you're teeth start chattering is it becuase yuotr brain isn't fu nctioning, is it another way you talk crap ?

It means there's a 20% chance of it raining. Which means that if there were 5 days like that then on one day yuo'd be pretty certain of it raining but not on other days. But you do need a functioning brain for such informatiuon to mean anything.

Why it's useless, they chance of it raining the whole day i.e 24 hours is not very likely. And if it's 10% it'll mean it'll rain for 2.4 hours. But that doesn't tell you when either.

Well my BBC weather app tells me that in east London in the next hour theres will be heavy rain 18C 12 mph wind. Symbols for UV pollen and polution . sunrise 5:15 sunset 20:58 Far more useful than your pathetic % idea.

I've looked at hourly forecasts before, they're terribly inaccurate.

It's useless information. A light shower for 5 minutes or a heavy downpour for an entire day both come under that prediction.

I can think of many days where it's just kept on raining. Clouds hunt in packs.

I have, as I explained above. Once it's winter i'll try to make a video. My digital camera will record for 1 hour 10 minutes at a time.

It's shivering. The jaw is a powerful muscle, also used for tearing up meat.
