For every sudden or significant change in the air pressure, the weather icons will
update accordingly to represent the change in weather.
(Every time a new average pressure value has been obtained (once per minute), this
value is compared with an internal reference value. If the difference between these
values is bigger than the selected weather tendency threshold, the weather-icon
changes, either for worse or for better. In this case, the current pressure value
becomes the new weather tendency reference.)
