Isotherms are used in forecasting to illustrate what?

Isotherms are lines of equal temperature, used on weather maps to show how temperature varies across an area. Connecting points with the same temperature lets forecasters see temperature gradients. When the isotherms are tightly spaced, the temperature changes quickly over a short distance, indicating a strong gradient and often a frontal zone that strongly influences wind and the movement of pressure systems. When the lines are spaced farther apart, the gradient is weaker and the air mass is more uniform. This temperature pattern helps predict front movement, areas of warming or cooling, and how winds may respond to those temperature contrasts. Humidity, wind speed, and precipitation are represented by different contours: lines of equal humidity (or dew point) for moisture, lines of equal wind speed for isotachs, and lines of equal rainfall for isohyets.
