Pressure Trend Arrow or Weather Tendency Indicators

What does that arrow on my 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 indicator points downwards, the air-pressure is falling and the weather is expected to become worse.  An arrow to the right means no change.
