to “clouds with rain” or the reverse.

although it is possible for the change to occur quickly.

Weather Tendency Arrows

Along with the forecast icon there
is a pressure tendency arrow.

There is one that points up (on the
left side of the LCD) and one that
points down (on the right side of
the LCD).
3.
These arrows reflect current changes in the air pressure.
4.
An arrow pointing up indicates that the air pressure is increasing
and the weather is expected to improve or remain good.
5.
An arrow pointing down indicates that the air pressure is
decreasing and the weather is expected to become worse or remain
poor.
6.
No arrow means the pressure is stable.
7.
A storm can be expected if there is a drop of 4 hPa or more in less
than 6 hours. The
clouds with rain
icon will be displayed and the
tendency arrow that points down will be flashing—indicating the
storm warning feature has been activated. The flashing will stop
when the air pressure stabilizes or begins to rise.
