Weather report - Belgian Grand Prix.

The Ardennes region of Belgium is notorious for its fickle weather conditions, with the Belgian Grand Prix expecting anything from scorching sun to a torrential deluge - sometimes even both at the same time.

The initial outlook suggests low pressure in charge this weekend, bringing the likelihood of unsettled conditions, with plenty of 'shower activity' making for some very exciting sessions. While Michael Schumacher's eyes would undoubtedly light up at the thought of rain, all other eyes will be on Fernando Alonso and the possible end of his world championship quest. Would the Spaniard prefer rain or shine?
