....why is it STILL impossible to get accurate actual weather for areas away from airports ??
Look at
this website.
It's a world-wide weather site. You can search by the town or airport that you are interested in. But, the great thing about it is the list of on-line personal weather stations that display actual weather continuously.
This view is of Gloucestershire. There is an on-line weather station at Bishops Cleeve - about three miles west of the crash site at Winchcombe. Click on the numbered circles for the weather.
Granted, it's not a certified met-man running it, but the information available gives a pretty good indication of the actual conditions locally.
Have a look and see what you think.
Interesting to see that Staverton isn't too far from Winchcombe, they should know the local conditions, shouldn't they?
