Pressure and weather in Pearland
Pearland sits on the Gulf coastal prairie in Brazoria County, low, flat and only a short drive from Galveston Bay, which means the atmosphere overhead is nearly always loaded with moisture. Most of the year the barometer here is remarkably lazy, held in a narrow range by the Bermuda high while the sea breeze pushes inland each afternoon and sets off thunderstorms along the convergence line, sometimes right over town and sometimes twenty miles the other side of Houston. The two exceptions are dramatic. From June through November tropical systems in the Gulf can produce the deepest pressure falls the region ever sees, and even a storm that stays offshore will pull the current barometric pressure down noticeably for a day or two while feeding in bands of heavy rain. Flooding, not wind, is the usual local consequence, as Harvey demonstrated. The other exception is the winter cold front, the classic Texas norther, when a shallow but powerful Arctic air mass surges south across the prairie, the wind snaps around to the north, the dew point collapses twenty degrees in an hour and the barometer climbs steeply behind it. A barometric pressure forecast for Pearland matters most in hurricane season and during winter frontal passages.
What this means for you
Can barometric pressure cause headaches? A Texas norther is a rising-pressure event with a huge humidity drop, while a tropical system is a falling-pressure event with humidity staying high, so the two make a natural experiment. Log both in Pressure Pal as a headache tracking app and see which direction matters for you.
