Chapman has a continental climate, with hot summers and cold winters. Weather can change quickly because the town lies in the Great Plains. Spring and summer often bring thunderstorms, heavy rain, strong winds, hail, and sometimes tornadoes. Most of the yearly rain falls from spring through early fall.
Air pressure helps shape these changes. High pressure often brings clear, dry weather and light winds. Low pressure can pull warm, moist air north from the Gulf of Mexico. When this air meets cooler, drier air from the north or west, fronts can form storms. Winter low pressure systems may bring snow, ice, and strong winds.
Chapman’s mostly flat land allows air masses to move across the area with few natural barriers. The Rocky Mountains to the west can help create dry air, while the Gulf of Mexico supplies moisture from the south. Summers are usually warm to hot and humid, fall is cooler and often calmer, winters are cold with occasional snow, and spring is mild but changeable.
