Forecast

Barometric pressure in Andalusia, Alabama is influenced by its inland location. It is not directly affected by coastal phenomena. Instead, it is shaped by changes in temperature and humidity. These fluctuations cause the pressure to rise and fall.

The city is nestled in the southeastern United States, surrounded by rolling hills and forests. The landscape creates a rain shadow effect, blocking moisture from the Gulf of Mexico. As a result, atmospheric pressure is affected by the clash of dry and humid air masses. This leads to varied and unpredictable weather patterns.

The surrounding hills and forests also contribute to temperature extremes. Cold air sinks into the valleys, while warm air rises over the hills. This creates microclimates with distinct temperature and humidity profiles. These microclimates, in turn, influence the local barometric pressure.

In winter, cold fronts bring dry air from the north, causing pressure to drop. In summer, warm air from the Gulf of Mexico brings humidity, causing pressure to rise. This continuous cycle of pressure changes shapes the local weather in Andalusia.
