In a complex weather situation involving light rain showers, light snow showers, and a thunderstorm, what is the correct order for entries?

In reporting complex weather conditions, the correct order of entries follows a structured format that prioritizes the weather phenomena based on their intensity, type, and duration. When rain, snow, and a thunderstorm occur together, they should be described with clear indications of their intensity.

The format typically starts with the most significant weather event having the greatest potential impact. Thunderstorms are usually classified as more severe than light rain or snowfall, hence they are reported first. The presence of light rain and light snow shows that these types of precipitation can occur simultaneously but are lesser in intensity compared to thunderstorms.

The correct entry systematically lists these events: starting with the thunderstorm, followed by light snow, and then light rain. This organization signifies not just what conditions exist but also their relative strength and effect, which is crucial for accurate communication in aviation contexts.

The representation of the information using 'TSSNRA' combines shorthand for thunderstorms (TS), light snow (SN), and light rain (RA) appropriately, with the dash prefacing the thunderstorm to indicate it as the primary event before the other lesser significant weather phenomena. This effectively communicates the status of current weather conditions with clarity and specificity.
