Final answer:
The weather in Western Canada following a cold front would most likely be snowy and cold due to the typical decrease in temperature after a cold front passes. The continental climate of central Canada and the rain shadow effect from mountain ranges contribute to this expectation.
Step-by-step explanation:
In Western Canada, following a cold front, the likely weather experience would be snowy and cold weather. Cold fronts are associated with falling temperatures and a change in weather patterns. The passage of a cold front typically results in clear skies, a sharp decrease in temperature, and sometimes, depending on moisture availability, precipitation in the form of snow. Given the continental Type D climate that is common in central Canada, with its warm summers and cold winters, it is reasonable to expect colder conditions after a cold front. The phenomenon of a cold front dropping temperature significantly often leads to wintry weather conditions, especially during the colder months.
It is worth considering the rain shadow effect, which affects the western parts of North America. The presence of mountain ranges can influence the amount of precipitation an area receives after the passage of a cold front. In Western Canada, these factors contribute to the potential for snowy and cold weather following a cold front, aligning with option 3 from the question presented.
