Hourly Pressure Trends
Track the barometric pressure in Charleston hour by hour across the next 6 hourly readings.
Charleston, West Virginia's barometric pressure is influenced by its inland location. Pressure systems from the Atlantic Ocean and Gulf of Mexico affect the city. These systems bring changes in pressure, resulting in varying weather conditions.
The city is surrounded by the Appalachian Mountains to the east and southeast. This mountainous terrain disrupts airflow, causing pressure changes. The Kanawha River Valley, where Charleston is situated, also plays a role. It channels airflow, further influencing pressure systems.
The combination of mountain and valley terrain creates a unique environment. Air masses are forced to rise, resulting in weather pattern changes. This contributes to Charleston's complex weather conditions.
