48-hour migraine risk based on barometric pressure, humidity, and temperature changes in San Antonio.

Spring severe weather season brings the most dramatic pressure events as Gulf moisture clashes with Pacific dry air over the Hill Country. Fall tropical moisture surges from the Gulf can also produce rapid pressure drops and flooding rains.

San Antonio sits at the ecological boundary between the humid Gulf Coast and the semi-arid Hill Country.
