What does "TS FZRA" report in terms of weather conditions?

The term "TS FZRA" is a coded way to report weather conditions in meteorological language. In this context, "TS" represents a thunderstorm, while "FZRA" signifies freezing rain. The presence of "FZRA" indicates that the precipitation is falling as rain but the temperature is low enough to cause the rain to freeze upon contact with surfaces, creating hazardous conditions.

This interpretation helps meteorologists and observers quickly understand the specific weather risks. The inclusion of both "TS" and "FZRA" in the report highlights a situation where a thunderstorm is occurring simultaneously with freezing rain, which can lead to dangerous travel conditions and ice accumulation on surfaces, compounding the hazards of the thunderstorm itself.

The other options do not accurately describe the combination of conditions indicated by "TS FZRA." Regular thunderstorms would not highlight the freezing aspect of rain, while thunderstorms with light rain or snow do not capture the severity of the freezing rain condition. Thus, answer B is the correct choice, providing a clear understanding of the specific weather phenomena being reported.
