Predictions are based on the direction it is moving. You have to watch it 
over time. If it is rising, the weather is getting better (high pressure = 
sunshine). If it is falling, bad weather is coming (low pressure = 
clouds/rain). Since altimeters work by measuring pressure too, going up and 
down mountains may affect the relative movement.
