Pressure and weather in Decatur​

Gulf moisture feeds lows and fronts crossing the Tennessee Valley, especially during the spring severe-weather season. Autumn and winter frontal systems can also change pressure quickly; midsummer often brings more localized afternoon storms.

What this means for you​

For riverside activity near Point Mallard, record humidity and exertion before reviewing the barometric pressure forecast. Keep warning-driven schedule changes in the diary as well, since interrupted sleep or meals can accompany a stormy day.
