Forecast

The barometric pressure in Greensburg, Pennsylvania is influenced by its location in the interior of the eastern United States. It is subject to changes in air masses from the Gulf of Mexico and the Atlantic Ocean. These air masses bring different pressures and weather patterns to the region.

Greensburg is situated in a valley surrounded by the Allegheny Mountains to the east and the Laurel Highlands to the west. This landscape creates a unique microclimate in the city. The surrounding mountains block and redirect winds, which affects the local atmospheric pressure.

The mountainous terrain also leads to temperature and precipitation variations throughout the year. Cold air from Canada moves southward through the valley, bringing cold temperatures in the winter. Warm air from the Gulf of Mexico moves northward, bringing warm temperatures in the summer. These air masses meet in the region, resulting in varied weather conditions.
