Forecast

Columbia, Louisiana's air pressure is often high in the summer and low in the winter due to changing weather patterns.

Summer brings hot air from the Gulf of Mexico, increasing air pressure and causing heatwaves and storms.

Winters bring cold air from Canada, decreasing air pressure and leading to cooler temperatures and occasional frosts.

The nearby Mississippi River and surrounding flatlands affect air pressure, allowing cold air to move in easily.

Columbia's low elevation near the Gulf Coast also lets warm air from the ocean influence air pressure.

As a humid subtropical climate, Columbia's air pressure is often affected by the clash of warm, moist air from the Gulf and cool, dry air from Canada.

Summer's high air pressure and winter's low air pressure are typical of this climate type, leading to distinct seasonal weather patterns.
