At the end of the first day of practice at Brno, it was clear that there were two men a long way clear of the rest of the field. Casey Stoner and Valentino Rossi were over half a second ahead of the man in 3rd, and the only riders capable of cracking into the 1'57s. The timing sheets seemed to tell a fairly clear-cut story of two fast men, a pack of riders all very close to each other, and another disastrous failure by Michelin. The grid seemed to be shaping up nicely.
The problem was, Saturday's weather threw not so much a fly as a whale into the ointment, after a storm front unleashed torrential rain over the Czech track, leaving the circuit completely drenched, though still ridable. With more rain coming in during the day, the grid was going to reflect a slightly different reality than Friday's practice had revealed, and confusing the picture even more, the forecast for Sunday is for the usual warm, bone dry conditions we have come to expect from Brno over the years.
During the morning's free practice session, Casey Stoner had already proved quite emphatically that he is probably the best wet-weather rider in the world, by stomping all over the competition. And as qualifying started in a light drizzle, he continued in the same vein. On just his 2nd flying lap, the Australian took a 5 second lead over the rest of the field, leaving his rivals gasping for breath.
