It was cloudy and rainy the day before, will it be foggy the next morning?

I think fog is mainly related to temperature and humidity. For example, the temperature is low and the humidity is high the day before, and it may be foggy the next day. If you are at the seaside, it depends on the wind direction. Generally, the wind blows from the sea, and it is easy to fog when it meets cold air on land. Ha ha! Pure personal understanding, hehe
