Some years ago (approx. around 2004), when i was very much into winter climbing, all the major channels were reporting heavy snowfall predictions in that November made by Metcheck. I sharpened the axes and crampons in anticiption, only for it to be a complete load of tripe. I’ve never forgiven him/them for it. Was glad to hear of him being conviced a few years ago and i’ve never experienced many people say good things about Metcheck forecasts since. My opinion is skewed in the -ve, but I wouln’t give them the time of day. Stick with Metoffice, MWIS (mountains), XC weather (wind speeds), weatherline (specifically the Lake District) and the BBC, they are all effectively Metoffice forecasts, but with some local slight variations, more detail and/or specialist for specific sports.
