Rain is predicted for the entire weekend of the 2014 Formula One British Grand Prix, but so far during the initial practice session on Friday things have remained dry. The predicted maximum temperature for Sunday’s race is a cool 66 degrees F (19 degrees C) and humidity levels are expected to be around 63 percent. The good news is that wind speeds should be low.

As mentioned things were dry today but cloud cover is currently about 75 percent over the Silverstone circuit, where the British Grand Prix has been held since 1987. So far, Mercedes AMG’s Nico Rosberg has been quickest with a time of 1:35.424, followed by his teammate Lewis Hamilton and then Ferrari’s Fernando Alonso and Red Bull Racing’s Daniel Ricciardo.

There wasn’t much action today but Susie Wolff took part during official practice for the first time, replacing Valtteri Bottas at Williams. She ran a time of 1:44.212 but then suffered an engine problem and had to head back to the pits. Williams’ other driver Felipe Massa spun into a wall and damaged his car.

Caterham, which has just been sold, also had some problems. Test driver Robin Frijns, sitting in for Kamui Kobayshi, suffered car trouble and had to stay in the garage. Marcus Ericsson also spun off the track.

Going into qualifying tomorrow and Sunday’s eventual race, Nico Rosberg leads the 2014 Drivers’ Championship with a total of 165 points. Lewis Hamilton is second with 136 points, while rounding out the top three is Daniel Ricciardo with 83 points. Mercedes AMG is on an impressive 301 points in the Constructors’ Championship, over twice as many as second-placed Red Bull Racing (143) and three times as much as third-placed Ferrari (98).
