Final answer:
A cold front near Detroit is likely to cause rainy weather due to the uplift of warm air and subsequent cloud formation and precipitation.
Step-by-step explanation:
The weather in Detroit will likely be rainy because Mike noticed a cold front near Detroit. When a cold front approaches, it forces warmer air above it to rise, which often results in cloud formation and precipitation. Cold fronts are typically associated with sudden temperature drops and are more likely to produce quick, heavy rain showers or storms, compared to other types of fronts.
According to the given information, Mike noticed a(n) occluded front near Detroit. An occluded front occurs when a cold front catches up to a warm front, causing the warm air to be lifted and forming clouds and precipitation. Therefore, based on Mike's observation of an occluded front, it suggests that the weather in Detroit will likely be rainy.
