Pressure Trend
The pressure trend arrow indicates the current barometric trend, measured over
the last three hours. The pressure trend is updated every 15 minutes. The pres-
sure trend requires three hours of data in order to be calculated so it won’t dis-
play right away on a new station. The pressure trend is indicated on the console screen,
as long as the required data is available.
