Harrisburg is located in the Susquehanna Valley. The city is surrounded by mountains to the north and south. These mountains block airflow from the north. They also deflect airflow from the south.

The mountains' shape and height affect Harrisburg's weather patterns. They create a rain shadow effect, resulting in lower precipitation than neighboring cities. The mountains also influence local wind patterns, which in turn impact the barometric pressure.
