Practice sessions already took place Friday with plenty of sunshine and high temperature of 28 C (82 F).
An approaching cold front will bring a passing shower or two on Saturday when qualifying will take place.

Behind the front, temperatures will only rise to near 20 C (68 F) during the race which could pose handling issues for the drivers who practice and qualify in much warmer conditions.
