Blacksburg's barometric pressure fluctuates throughout the year. It drops during low-pressure systems, bringing rain and storms. It rises with high-pressure systems, bringing clear skies and fair weather.
The city is surrounded by mountains to the east and west. These mountains block and redirect air masses, affecting the local pressure. The New River Valley, where Blacksburg is located, is a relatively low-elevation area. This low elevation allows air to settle and stagnate, influencing the pressure.
Cooler air from the mountains can drain into the valley, causing pressure to drop. Conversely, warm air from the valley can rise, increasing pressure. The valley's shape and surrounding mountains create a unique microclimate, making Blacksburg's weather patterns distinct from surrounding areas.
