Pressure and weather in Conroe
Conroe sits in Montgomery County about forty miles north of Houston, on the southern edge of the East Texas Piney Woods with Lake Conroe on its western side and the Sam Houston National Forest beyond. The Gulf of Mexico is roughly sixty miles south across flat coastal plain, which is close enough that the marine air mass reaches here almost daily in summer and close enough that tropical systems arrive with most of their moisture intact. Barometric pressure here has a strongly seasonal character. Summer is dominated by a sprawling upper-level ridge that parks over Texas, suppressing storms, driving heat to extremes and holding the barometer high and almost motionless for weeks. The tropical season interrupts that: from August through September, systems moving in from the Gulf produce prolonged, deep falls in current barometric pressure, and the greater Houston region has learned that the slow-moving ones do far more damage through rainfall than through wind, as Harvey demonstrated in 2017 when it stalled and dropped historic totals across Montgomery County. The cool season from November through March brings a steady succession of cold fronts pushing down out of the Plains, each with a modest fall, a wind shift and a sharp drop in humidity behind. Spring is the severe weather peak, when Gulf moisture returning north meets those fronts and squall lines cross southeast Texas with fast, steep pressure drops. A barometric pressure forecast for Conroe matters most in spring and during hurricane season.
What this means for you
Can barometric pressure cause headaches? Southeast Texas swings between long motionless stretches under summer ridging and abrupt frontal passages that change pressure and humidity together within an hour. That contrast is why so many people here describe their symptoms as seasonal rather than constant.
