Mark Webber set the pace this afternoon in second practice for this Sunday's F1 2011 Belgian Grand Prix, and while proceedings started damp, the track did dry out and that was when all the quickest times were set.
Webber posted the marker for the day at the end of the second third of the session, his best lap a 1 minute 50.321 seconds, which put him 0.140 seconds up Fernando Alonso, who was also right on the pace in his Ferrari.
However with conditions deteriorating through the last half hour and the rain returning the times were effectively locked-in, ensuring the Aussie took the day one honours for Red Bull.
Brit's Jenson Button and Lewis Hamilton meanwhile were third and fourth for McLaren, both about half a second off Webber and the only other men in the 1m 50s bracket.
Felipe Massa was next up for Ferrari, while the Mercedes of Nico Rosberg rounded out the top six.
Behind F1 2011 rookie Sergio Perez and Force India test and reserve driver Nico Hulkenberg came in seventh and eighth, with Paul di Resta ninth in the other VJM04 and runaway championship leader, Sebastian Vettel tenth.
Michael Schumacher, who had been quickest in P1, took P11 with Pastor Maldonado, Kamui Kobayashi and the Toro Rosso's of Jaime Alguersuari and Sebastien Buemi in positions 12 through to 15.
Of the rest Rubens Barrichello was 16th - one spot ahead of fellow countryman Bruno Senna. Senna did 21 laps in P2, valuable mileage for the Lotus Renault pilot, who spun off in turn 9 in P1 and who has of course taken over the seat from Nick Heidfeld.
Of the 'newer' teams Jarno Trulli led the way for Team Lotus, while the HRT of Daniel Ricciardo and Vitaly Petrov brought up the rear, the latter out of position in his Lotus Renault due to a steering problem.
