My laptop is set up with weather from across the world from The Met Office. My wife's phone uses The Weather Channel for key information.
Firstly the Met Office and The Weather Channel frequently contradicted each other over a period of the six consecutive days when we monitored them.
Rain was promised on dozens of occasions - and cloudless skies filled with sunshine were their rather inconvenient replacements.
Thunder storms were predicted on a regular (80%) basis over a period of days. More cloudless skies full of cheerful sunshine.
The times of these broken promises must have changed at least forty times over the relevant days - and were still wrong.
When we checked other weather predictions from different sources - these were as bad - if not worse.
Add to this the present tendency to give % chances of the weather being correct - they were often 100% wrong.
If we can't tell weather over a matter of days - how on earth can climatologists be trusted to talk of weather patterns years into the future - rather a long time beyond the next fortnight?
