Uncertain weather is often a factor at the Formula One Canadian Grand Prix, and looking at the forecast for Montreal where the race is being held we’re expecting some rain during today’s practice session but clear conditions for tomorrow’s qualifying and Sunday’s eventual race. Peak temperature for Sunday is a mild 74 degrees F (23 degrees C), and both humidity and wind speed should be low.

The race is once again being held at the Circuit Gilles Villeneuve, a semi-permanent track located on the man-made Ile Notre Dame island in the St Lawrence river. Grip levels tend to fluctuate, particularly as the weekend proceeds and more rubber is put down. Pirelli has nominated its soft and supersoft tires for the race, the same combination used in the previous Monaco Grand Prix.

Most teams are expected to run major upgrades on their cars. In particular, Ferrari is thought to have made use of an engine upgrade allowance to help extract more power for the race. Another team to watch is Toro Rosso, and in particular its young driver Max Verstappen. The Dutch driver’s run into the rear of Lotus’ Romain Grosjean at the previous race in Monaco was called “dangerous” by Williams’ Felipe Massa, though Verstappen says he won’t be backing down from chasing points.

Going into tomorrow’s qualifying and Sunday’s race, Mercedes AMG’s Lewis Hamilton leads the 2015 Drivers’ Championship with 126 points. His teammate Nico Rosberg is second with 116 points, followed by Ferrari’s Sebastian Vettel in third with 98 points. In the Constructors’ Championship, Mercedes leads with 242 points followed by Ferrari with 158 points and Williams with 81 points.
