Experts from meteorological department pointed out that the reason why it snowed at that time is that the atmospheric pressure above the area dropped suddenly to 950 millibars. It was 20 millibars lower than the limit of the normal atmospheric pressure. In June, 2000, the temperature in Koppaonike City, a small town in the plain of Yugoslavia, was over 15 degrees centigrade all along. But in midday of June 17 it dropped suddenly to zero or below. Then a heavy snow fell on. This surprised the local residents. People went to street one after another to have a look.
