Pressure and weather in Pelham
Pelham lies in Shelby County where the last long sandstone ridges of the Appalachians run out to the southwest, with Oak Mountain rising directly to the east and the Cahaba River threading the valley alongside town. Those ridges are modest in height but they matter locally, channelling low-level winds along the southwest to northeast axis and helping to shelter parts of the valley on windy days. The regional weather story is Dixie Alley. Central Alabama sees two severe seasons, a long one from March into May and a sharper one in November, and the ingredient that makes them dangerous is the same low-level jet of Gulf moisture that also makes the humidity so heavy. When a strong upper trough moves east from Texas, the surface low deepens over Arkansas and the barometer at Pelham falls steadily for twelve to twenty-four hours before a squall line arrives, often after dark, followed by a rapid rise as much drier air pours in. Summers are stagnant and hot, with the barometer nearly flat and pop-up storms the only variety. Winter occasionally delivers freezing rain when cold air wedges south of the Appalachians. A barometric pressure forecast for Pelham is most useful in spring and late autumn.
What this means for you
Can barometric pressure cause headaches? Alabama severe weather frequently arrives overnight, so symptoms that begin the previous afternoon may be tracking the pressure fall rather than the storm itself. Use Pressure Pal as a migraine tracker app, note start times, and compare them against when pressure change today actually began.
