If one goes to the homepage of weatheraction.com right now then you can see these words from Piers Corbyn "Storms and floods 12th & 13th December 'stunning success' for WeatherAction", followed by more words of self congratulation. Unfortunately for Piers the whole effect is ruined by the following near the top and in larger font: "Xmas Eve - Major storm; Xmas Day - Snow!" Ahem, "Major storm ... Snow" - I don't think so Piers!! And he had been forecasting another of his storms for the end of the month - it's not happening Piers!
We have been, and still are, under the influence of a large anticyclone, what meteorologists refer to as a 'blocking high'. Good name as it blocks areas of low pressure trying to come in off the Atlantic. What we have here is another example of Piers painting a totally wrong scenario, not just something slightly wrong in detail. And of course this anticyclone has been affecting the whole country i.e. I'm looking at the big picture not just Devon and Cornwall.
With Piers it's so difficult to deduce that his methods work when his forecasts do turn out to be accurate if other forecasts by him for nearby time periods are so terribly terribly wrong. Thinking about December for a moment there is a very good chance of getting a bad storm affecting a large part of the country at some stage and the one mid month Piers is taking credit for is one such. Now hold on a moment, didn't Piers flag up six possible storms for December? He is allowing himself a tolerance of + or - one day in the timing of the storm (fair enough in my opinion) so any one storm could occur on any one of three days. Multiplying 3 by 6 is 18 according to me and any one day out of 18 for a 31 day month aren't bad odds in my opinion! So here's the question about the forecast by Piers for the storm on 12th/13th: did his techniques work or did he just strike lucky?
Finally, why I decided to use the title "Bookies should thank Piers Corbyn" can be deduced from a link to the 'Daily Star' from the 'Latest News' page on the WeatherAction website. The media story quotes Piers saying the following: "Our advice to beat the credit crunch is to place a bet on a white Christmas because it's never looked more likely". The bookies had stood to lose a lot of money (not only because of Piers it has to be said) but are now smiling after a good Christmas for them.
Piers was full of himself getting some bad weather correctly forecast much earlier in the month. Will he now publicly apologise for his wrong advice to those who bet on a white Christmas?
