Final answer:
Given the predicted drop in air pressure and temperatures, thunderstorms are the most likely weather condition for the area in the late afternoon. Fog is less likely under these conditions, and clear skies are usually linked to high pressure systems, not decreasing temperatures and pressures.Option D is the correct answer.
Step-by-step explanation:
The weather forecast predicts that air pressure and temperatures will drop during the day in a city that is currently at 75°F with partly cloudy skies.
Decreasing air pressure and temperature are typically associated with the arrival of weather fronts that can lead to varied weather conditions. Considering that the forecast does not mention any specific weather system aside from the pressure and temperature drop, the most likely weather outcome for this area late in the afternoon would be rain or thunderstorms. These are common occurrences when a cold front moves in, which can lower temperatures and air pressure and often results in precipitation.
Fog tends to form when there is a temperature inversion or during clear and still nights when the ground cools rapidly. Clear skies are generally associated with high pressure areas and not with falling temperatures and pressures. Taking into account the given data and typical weather patterns, the correct option for the type of weather most likely for this area in the late afternoon is d) Thunderstorms.
