What are the TV forecasters talking about?

High pressure, Low pressure, fronts, shearlines, windward & mauka showers...what does it all mean? Here's a basic guide to help you understand the weather forecasts on television:

High Pressure: That big "H" on the weather map marks the center of a High Pressure cell. When air from above sinks down towards the earth, it creates high pressure. High Pressure gives us good weather. Clouds can't grow and build into big storms because the sinking air pushes down on the clouds.

Low Pressure: The big "L" on the weather map is the center of a Low Pressure cell. Low pressure means air is rising and usually indicates bad weather. When air rises, it is considered unstable. Low pressure usually brings more clouds and rain. Clouds can grow bigger and taller when air rises. All storms (thunderstorms, cold fronts, Kona Lows, Hurricanes, Tornadoes, etc) are a result of very low pressure.
