What do the arrows on my weather station mean?

Many of our stations offer a pressure trend arrow/weather tendency indicator.  In general, working together with the weather forecast icons are the pressure tend arrow/weather tendency indicators. When the indicator points upwards, it means that the air pressure is increasing and the weather is expected to improve, but when the indicator points downwards, the air pressure is falling and the weather is expected to become worse.  An arrow to the right means no change.

For complete details on your specific station, please check your owner's manual.
