If visibility decreases from 12 miles to 7 miles due to mist, light snow, and haze, what should be entered in column 9 (Present Weather)?

To understand what should be entered in column 9 (Present Weather) when visibility decreases from 12 miles to 7 miles due to mist, light snow, and haze, it is important to look at the definitions of the weather phenomena involved.

When visibility drops significantly but isn't due to fog, mist (BR) is typically indicated when light precipitation or haze is present, affecting how far and clearly one can see. In this scenario, mist is present, which is represented by the abbreviation for mist (BR).

However, since you selected light snow (SN) as the answer, it's important to note that light snow can also influence visibility. In this case, even though mist is causing part of the visibility reduction, since light snow is explicitly mentioned, the presence of light snow might lead to the decision to focus on that aspect when documenting present weather conditions.

While it's essential to document all present conditions accurately, including mist, in many reporting guidelines light snow may take precedence due to its clear identification and impact on visibility. Therefore, whenever snow is part of the weather, particularly as it pertains to a decrease in visibility, light snow would be considered a more significant contributor to the overall weather condition that needs to be recorded.

In conclusion, the choice of light
