When checking the weather what does the pressure tell you?

In: 503

Answer 1

Atmospheric pressure isn’t the same everywhere and isn’t constant for any given location. It might be helpful to think of it like a hilly landscape and poor weather is like water running down hill. If you have high pressure or it looks like a high pressure zone is moving your way, clear weather is likely; that’s like standing on top of a hill. If pressure is dropping, that’s like walking down from the hill into a valley where the water is pooling. The lower you go the more likely you are to encounter precipitation
