In St. Louis, the barometric pressure tends to fluctuate throughout the year. During the summer months, the pressure is typically lower, while in the winter, it is generally higher. These changes in barometric pressure are influenced by the shifting seasons, with warmer air rising and cooler air descending.
The landscape around St. Louis, characterized by the convergence of the Mississippi and Missouri Rivers, plays a role in the atmospheric pressure. The presence of these rivers and the surrounding hills can create a more stable climate, often leading to less extreme variations in barometric pressure compared to areas with more open plains or coastal locations. Additionally, the city's proximity to the Great Plains and the Gulf of Mexico can result in occasional weather systems that can impact the barometric pressure, bringing changes in St. Louis' weather patterns.
