Forecast

The barometric pressure in Fort Smith, Arkansas, is influenced by the city's location in a valley. The pressure can fluctuate significantly over short periods. Changes in pressure can bring different weather patterns. Sudden drops in pressure often signal the approach of a low-pressure system, which can bring rain and storms. Conversely, rising pressure usually indicates fair weather.

Fort Smith is situated in the Arkansas River Valley, surrounded by the Ouachita Mountains to the south and the Ozark Mountains to the north. This unique landscape creates channels for air to move through, influencing local pressure patterns. The mountains can block or redirect air masses, leading to significant changes in pressure. The valley's low elevation also allows air to settle and stagnate, further affecting pressure readings.
