Yes.
There is no 'guff', just a good explanation of what might happen and how it could change.
He is particularly good at picking up detail as to whether it will be a damp cloudy day or a wet cloudy day, if you know what I mean.

I subscribe, and have for a number of years so I must value it enough to keep paying :unsure:
To be honest the longer range stuff really is pointless. Yes, its interesting to hear what the models are saying, and how they are changing, but I've yet to ever hear a long range prediction that was right, other than when they say it'll be 'changeable'. And this isn't a criticism of Simon Keeling, its a criticism of all the weather models - none of them are at all accurate more than a few days out. Maybe up to 5-6 days out when there's a step change in the weather, from wet to dry, from average to severe wintry weather. Beyond that you might as well chuck a dart at a sheet of paper with all the outcomes written on it, it would be right as often as the models are. For example not one weather model predicted the long hot summer of 2022 a month out. Or the Beast from the East in 2018. They all just revert to 'average conditions' the further out you go. So they never pick up extremes.

Simon's short range forecast (the 5 day one) is pretty good at the general overall UK weather situation, but they won't help if your location is close to a dividing line between wet and dry for example. All his longer range stuff suffers from all the issues mentioned above, as do all weather forecasting sites.

That all being said I still watch his forecasts regularly, recently more in hope than expectation........

I think you have to stick with a forecaster for a little while and 'learn' how to use them.
I will look at weather forecasts from any source I can but I find weatherweb to be consistently the best.
Most forecasts are pretty good for the next 24 hours but get 'spun' by the popular media outlets for storytelling rather than accuracy.
Simon Keeling is excellent and it can be disappointing if you really need an accurate forecast and it's one of his cohorts doing the forecast instead. They aren't bad, just not as good.
Most importantly, he tells it like it is. No spin. This is what the models say. I think they are right or actually I think they may be wrong.
I find the long term/ seasonal forecasts very helpful. They are never going to accurate for any particular week but can give a very clear idea of a general trend and used in conjunction with short term forecasts, they can indicate the likely outcome when models lose their way.

It would be interesting to hear @Simon Keeling thoughts on longer range (month ahead) forecasts and whether he thinks that forecasting weather any further ahead is just a pipe dream as the atmosphere is changing all the time.
