The weather looks great for the Detroit Grand Prix weekend. A large high pressure system will be slowly drifting west across the Great Lakes region, which will provide dry conditions throughout the event. The temperature will get very warm on Friday and Saturday, into the lower 90s. But a cold front is expected to pass through the area from the north on Saturday night, which will bring cooler temperatures on Sunday. No rain is expected with the frontal passage. Winds will be fairly light through the weekend, less than 10 mph, and generally from the northeast.
