Today's barometric pressure in Arlington, a 48-hour pressure chart, and a risk score for weather-triggered migraine and headache, based on pressure drops, humidity, and temperature changes.
Loading live forecast for 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.
2026 index: Arlington is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
