Then I heard it. For ten to fifteen minutes, the distant buildings and trees disappeared behind the aqueous curtain. And then, as quickly as it had exited, the sun's light burst forth, reflecting in multicoloured hues from the oil-water melange on the pavement below. But showers are also very common during April across most of North America. And in this month, they can often be snow showers as well as rain showers, particularly in Canada and the northern tier of States.
Showers are a distinct form of the fall of precipitation, rain or snow.
The keys here are falling from a convective cloud and suddenness . Showers are not generally associated with those large-scale storms which dominate winter precipitation when precipitation usually falls steadily from stratiform clouds surrounding the low pressure cell. However, in areas such as the Great Lakes Basin, much snow may fall as snow showers or snow squalls in the cold air before or after the storm system when convective clouds boil up as the cold air crosses relatively warm waters. April showers are more than just a poetic choice of words to rhyme with flowers . You see, April is a transitional month in much of North America in the character of precipitation.
