When planning a summertime camping trip, people check the weather forecast for the possibility of favourable conditions. In Alberta a common saying is, “If you don’t like the weather, just wait a minute.” This saying indicates that the weather in Alberta can be unsettled at times.

 

A weather forecast tries to predict the likely outcome of the weather, but sometimes it may be wrong. Why might this be?
