Glen Allen is situated in the eastern United States, near the Atlantic Ocean. The city is surrounded by gentle hills and vast plains. These geographical features influence the atmospheric pressure. The ocean air brings moisture, which affects the pressure.
The surrounding hills create a partial barrier, blocking cold air from the north. This keeps the pressure relatively stable during winter months. In contrast, the plains allow warm air from the south to enter, raising the pressure during summer.
