Pressure and weather in Schertz
Schertz lies northeast of San Antonio where Bexar, Comal and Guadalupe counties meet, just off the Balcones Escarpment on the gently sloping Gulf coastal plain. Its humid subtropical climate is defined by a tug-of-war between two air masses, and barometric pressure is the clearest record of who is winning. For much of the year moist air streams north off the Gulf of Mexico, keeping current barometric pressure relatively low and humidity high. Then, from autumn through spring, a blue norther arrives: a cold front sweeping down from the plains with almost no terrain to slow it, dropping the temperature sharply within an hour and driving one of the most abrupt pressure rises seen anywhere in North America. Those frontal boundaries stalling near the escarpment are also what make this corner of Texas so storm-prone, since Gulf moisture riding up over the higher ground to the northwest feeds the severe thunderstorms and flash flooding that give the Hill Country edge its reputation. Late summer adds the possibility of a tropical system or its remnants moving inland from the Gulf, bringing a slower, deeper fall in atmospheric pressure today. Midsummer, by contrast, often locks in under a hot upper ridge with little pressure movement at all. For weather-sensitive residents, a barometric pressure forecast for Schertz matters most during the cool-season frontal passages and the spring storm season.
What this means for you
Can barometric pressure cause headaches? In south-central Texas the norther is the pattern to watch, because barometric pressure can climb steeply in the same few hours the temperature collapses. Using this barometric pressure forecast with a migraine tracker app like Pressure Pal lets you see the front coming instead of feeling it first. Track barometric pressure today and get alerts when pressure change today is about to accelerate.
