Flying through any front, a change in which variables is expected?

• A. Temp, wind, and pressure
• B. Humidity, wind, and temperature
• C. Wind, humidity, and visibility
• D. Temperature, dew point, and pressure

Answer: (A)

Crossing a front typically brings changes in temperature, wind, and pressure. A front is the boundary between two contrasting air masses, so you’ll often feel a noticeable temperature shift as you move from one side to the other. The wind can shift direction and often increase in speed near the front due to the differing air masses and the resulting pressure gradients. Pressure tends to change as the front passes, which you can sense as a rapid or noticeable change in the barometric pressure you’re flying through.

Humidity and visibility can vary with fronts, especially with rain or clouds, but they’re not as consistent a signal across all fronts as temperature, wind, and pressure. So the most reliable set of changes you’d expect when flying through any front is temperature, wind, and pressure.
