Hail,sleet,hailstones,sunstroke all possible at the tt, rain solid for a fortnight in 1981,check the old dvds,however I only remember the sunny times,so bring it on.As for forecasts, remember when the bbc used to have 5 days forecasts on the website... so many folks were taking pics of quite the opposite weather happening outside their windows with the computer screens in the foreground.Anyone been at ginger hall when the mists roll in ? John surtees fairing " shot peened" by hailstones,finally tarmac doesn't melt the same. now with the use of "tropical" bitumen.
