That would likely explain some of the difference in temperature.

Also, one of the forecasts uses a single word to represent the

weather over a period of time at a location. The other one uses

several sentences to try and communicate the weather over a period of

time.

I note that the rain in the forecast is not due till the end of the

night. So if you have to provide a description of the night's weather

in one word, which word should you use? Wet, to represent a small

interval of time right at the end of the forecast? Or dry, to

represent the other 11 hours of the night?



These are communication challenges that the MetO are very well aware

of, as they have been in this game for a long time. They do give

guidance on interpretation of forecasts too - and the emphasis of

that guidance is (and always has been) to use the human-written text

forecast. Location-based forecasts are there to use in addition, but

the MetO advise that you remain aware of their shortcomings.

Well I realise that one covered a wider area but it did include London whereas -was the other the City of London, if so then the City of London must have it's own micro climate where it only rains in the surrounding areas.

I'm perfectly happy with a general regional forecast , all this Statement of Purose tripe has the MetO trying to forecast for individual square meters and apologising when they can't.
