F1 looks set to get more rain in Brazil this weekend, though at this stage it is not clear whether it will interfere with qualifying over the race.

The radar-watchers on Twitter report rain will hit the circuit on Friday evening, which could linger long enough to interfere with final practice on Saturday and possibly qualifying too. You can see the radar here.

The Brazilian Meterological Institute expects particularly heavy rainfall and thunderstorms on Friday.

Air temperatures should remain reasonably high, ranging from the high teens to the high 20s (Celsius), though becoming slightly cooler as the weekend progresses.

The weather has played a crucial role in recent Brazilian Grands Prix. Last year’s qualifying session was delayed due to a downpour, and rain showers shaped the epic championship deciding race there in 2008.

There was no rain in 2007 but very hot weather led to a post-race dispute over fuel temperatures.
