In the TAF for KMEM, what does 'SHRA' stand for?

The term "SHRA" in the TAF (Terminal Aerodrome Forecast) stands for "showers of rain." This abbreviation is part of the standardized meteorological shorthand used in aviation weather reporting. When a TAF includes "SHRA," it indicates that rain showers are expected at the location specified, giving pilots critical information to prepare for potentially reducing visibility and altering flight plans due to weather conditions.

The other options do not accurately represent what "SHRA" means in aviation weather terminology. A shift in wind direction would typically be expressed through the relevant wind direction and speed rather than using "SHRA." Similarly, while significant changes in precipitation could refer to weather conditions, they wouldn't specifically indicate a type of precipitation like rain showers. Lastly, "SHRA" does not reference severe thunderstorm warnings, as these would be indicated separately through different terminology or descriptors in weather reports.
