48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Arlington.
Arlington sits between Dallas and Fort Worth on the Blackland Prairie, directly in the corridor where Gulf moisture and continental air collide. Pressure runs near 994 hPa and can fall to 981 during severe weather, with 24-hour swings reaching 12 hPa.
Worst season for migraines: January through March. Cold fronts sweeping the prairie make the first three months of the year the sharpest. A second and more violent season follows in spring, when the dryline sets up west of the metroplex and fires storms eastward.
Common triggers in Arlington: dryline convection moving in from the west, blue norther frontal surges, late spring hail-producing supercells. Because Arlington sits mid-metroplex, it catches weather from both the Fort Worth side, closer to the dryline, and the Dallas side, closer to Gulf moisture. Blue northers can drop temperatures 20 degrees in an afternoon while the barometer climbs sharply behind the front, a combination residents describe as unmistakable.
Typical pressure: Arlington averages 994 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 981 hPa. Swings of 6-12 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Arlington weather trigger migraines?
Yes. Arlington experiences 6-12 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include dryline convection moving in from the west, blue norther frontal surges, late spring hail-producing supercells.
What time of year are migraines worst in Arlington?
In Arlington the most barometrically volatile stretch of the year falls in January through March. That is when weather is most likely to play a part, if weather is a trigger for you at all.

Is it really the weather?
Weather gets blamed for a lot of migraines, but it's hard to know if it's really behind yours. The MigrAid app saves the barometric pressure with every migraine you log, so after a few weeks you can see whether Arlington's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
