Forecast

The barometric pressure in Harrisburg, Pennsylvania is influenced by the city's location in the eastern United States. It is affected by the movement of high and low-pressure systems from the Atlantic Ocean. These systems bring different types of weather to the city throughout the year.

Harrisburg is situated in the Susquehanna River Valley. The surrounding mountains to the north and west of the city have an impact on the atmospheric pressure. They can block or redirect air masses, leading to changes in the pressure. The landscape also contributes to the formation of fog in the valley.

The city's proximity to the ocean also plays a role in its weather patterns. Moist air from the Atlantic moves into the region, resulting in precipitation. The Appalachian Mountains to the west of Harrisburg can force this air to rise, cool, and condense, leading to rain or snow.
