over a period of several hours a barometer rapidly decreasing air pressure. What type of weather will most likely most likely occur next

Explanation:

As the changes in the atmosphere take place the temperature tends to decrease or increase and this falling and the rising of the temperature creates a set of conditions that influences the day and the night temperature and thus leads to high and a low temperatures on earth landscape that is also indicated by the barometers. The low temperature might lead to the creation of the rainfall as the area may have an underlying high pressure first or intense cooling, may result in the formation of a snowy weather phenomenon.
