You and your friend decide to go on a weekend road trip to the nearby mountains. In your car is a barometer that reads 1003 mb as you leave home. Later, you arrive in the mountains and make the long,winding drive up to Summit Lodge, a motel known for its great view of the valley below. You notice that the barometer reads 960 mb. Your friend says,"That’s an extremely low pressure, which means a strong storm must be coming. We better head back home right now.' How would you reason with your friend to save the weekend?
