BEYOND THE FORECAST: WHAT IS THE DIFFERENCE BETWEEN HIGH PRESSURE AND LOW PRESSURE?

High pressure means the air pressure at a location is higher than at all surrounding locations; low pressure, the air pressure is lower. The distance between high and low pressure centers on weather maps is typically several hundred miles, but this can vary greatly depending on the weather situation. High pressure areas are usually associated with fair, dry weather; low pressures are associated with clouds and precipitation.
