Lee carded a four-under 68 to go nine under overall after a foggy morning delayed the start of play, meaning the round will be completed on Saturday.
He even had to come off the course for nearly an hour and a half early in his round, before birdying the 3rd, 7th, 11th, 16th and 18th to take a two-shot lead over Thomas Levet of France.
“It was very tricky out there,” he said. “Early doors it was pretty cold and then the fog came down and there was a delay so it was pretty hard to focus and get back into it again, but I managed to do that."
Six-times European Tour winner Levet admitted the conditions were very tough.
“It was difficult today,” he said. “The wind was blowing and stopping and the rain was on and off so it wasn’t easy to control the ball.”
Another former Ryder Cup player, Soren Hansen, was a shot behind Levet on six under, alongside Frenchman Christophe Brazillier.
