I think that raises some interesting points, although I'm not sure this is the best thread in which to discuss them:
1. IMO, they're one of the most useful parts of the Met Office website. Even if they only flag possible deviations from climatology, with an indication of the strength of the signal, they're worthwhile. Therefore, I hope they continue, although I agree that at times they could be written better.
2. It's very interesting meteorologically, but with every passing SSW, the link between these events and significant cold outbreaks in the UK seems more and more tenuous to me.
3. As far as I can recall, there was no SSW, but the event was picked up about a month ahead and consistently forecast. Since then, I don't think there has been any significant improvement in the 2–4-week range, although I'll stand corrected on that. That in itself raises questions about the value of AI models at these longer ranges, because you would expect to start seeing improvements by now.
