Note: animated weather forecast depends on changes of atmosphere pres-
sure. Viewing temporary histograms you can estimate the degree or possibility
of weather conditions, forecast by meteorological station. For example if during
the last 1 hours pressure has been constantly growing and then decreased a
bit during the next  hours, the meteorological station can forecast rain, but the
possibility of rain is low. On the other part, if there is sudden drop in the atmo-
sphere pressure, there is high possibility of heavy rain.
