The Weather Tendency Indicator - La Crosse Technology DCF-77 Instruction Manual

when really it is due to the slight change of altitude. Again, disregard
weather forecasts for the next 12 to 24 hours as this will allow time for
operation at a constant altitude.

THE WEATHER TENDENCY INDICATOR

Working together with the weather icons are the weather tendency
indicators (located on the left and right hand side of the weather icons).
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 dropping and the weather is
expected to become worse.
Taking this into account, you will see how the weather has changed and
how it is expected to change. For example, if the indicator is pointing
downwards together with cloud and sun icons, then the last noticeable
change in the weather was when it was sunny (sun icon only). Therefore,
the next change in the weather will be the cloud with rain icons since the
indicator is pointing downwards.
Note :
Once the weather tendency indicator has registered a change in the air
pressure, it will remain permanently visualized on the LCD.
