Weather is often very changeable in the area surrounding the Spa-Francorchamps circuit, home of the Formula One Belgian Grand Prix. We’ve already seen this during the earlier practice session on Friday, where intermittent rain fell throughout much of the session.

The current weather prediction for this weekend’s Belgian Grand Prix is showers during both tomorrow’s qualifying and Sunday’s eventual race. Peak temperature meanwhile is expected to be a mild 70 degrees F (21 degrees C).

The trouble at Spa is that the length of the circuit, which stretches 4.35 miles and is the longest on the calendar, makes it difficult for teams to select the optimal tires. It can be very wet on some parts of the circuit while it stays completely dry on others. Pirelli has nominated its P Zero Orange hard and P Zero White medium compounds, though at this point it looks like the Cinturato Green intermediate and Cinturato Blue wets will be seeing more action.

So far during Friday’s practice, Red Bull Racing’s Sebastian Vettel, sporting a new look after the summer break, has been quickest, followed by his teammate Mark Webber and Lotus’ Romain Grosjean.

Going into qualifying tomorrow and Sunday’s race,  Sebastian Vettel remains at the top of the Drivers’ Championship standings, with 172 points. Lotus’ Kimi Räikkönen is in second with 134 points and is just one ahead of Ferrari’s Fernando Alonso in third. In the Constructors’ Championship, Red Bull Racing commands 277 points versus the 208 points of Mercedes AMG and the 194 points of Ferrari.
