What weather condition is typically a result of high humidity and low pressure?

Heavy rainfall is typically associated with high humidity and low pressure due to the ability of the air to hold moisture. In low-pressure systems, the air rises, which leads to cooling and condensation of water vapor present in the atmosphere. As this moisture condenses, it can form clouds, and when enough water droplets combine, they eventually fall as precipitation. High humidity indicates that there is a significant amount of moisture in the air, which further contributes to cloud formation and the potential for heavy rainfall.

In contrast, clear skies are usually present in high-pressure systems, where sinking air inhibits cloud formation. Cold winds are generally associated with certain pressure systems and temperature gradients, while sunny weather often pairs with high-pressure systems where clear skies are prevalent.
