Final answer:
Heavy snow showers and low temperatures in Buffalo, New York are typically the result of a cold front and may be exacerbated by low-pressure systems and the lake-effect snow due to Buffalo's proximity to the Great Lakes.
Step-by-step explanation:
Heavy snow showers and low temperatures in Buffalo, New York are most likely caused by a cold front. When a cold front moves into an area, it brings a rapid drop in temperature and often leads to the development of precipitative weather conditions, including snow, especially if the temperatures are low enough. In the context of Buffalo, which is known for its cold and snowy winters, a cold front can intensify these conditions, resulting in heavy snow showers.
In terms of weather, low-pressure systems also play a role because they are associated with moist air rising and condensing, leading to cloud formation and precipitation. Buffalo's geographical location near the Great Lakes can enhance snowfall through a process known as lake-effect snow, where cold air moves over the relatively warmer lake waters, picking up moisture and then dropping it as snow on the leeward shores.
