Rockwall's weather is affected by its location in the southern Great Plains, where warm, moist air from the Gulf of Mexico meets dry air from the west. This clash of air masses causes changes in air pressure, leading to varying weather patterns throughout the year. Rockwall's flat, low-lying geography allows winds to move freely, making it prone to pressure changes and weather shifts. In the spring, warm air brings rising pressure and fair weather, while in the fall, cooler air brings falling pressure and stormy weather. Summer's hot, dry air leads to high pressure and heatwaves, while winter's cold air brings low pressure and cold fronts. Rockwall has a humid subtropical climate, characterized by hot summers and mild winters, with air pressure playing a key role in shaping its weather patterns.
