Pressure and weather in Keller
Keller sits on the Grand Prairie north of Fort Worth, on terrain flat enough that nothing slows an approaching air mass. Two features drive the barometer. The first is the dryline, an invisible boundary between dry air off the Chihuahuan Desert and humid Gulf air that sets up west of the metroplex on most spring afternoons and then surges east. When it passes, dewpoints crash, pressure rises abruptly behind it, and severe storms fire along the boundary. The second is the blue norther, a cold front that can drop the temperature forty degrees in a couple of hours between November and February and sends the barometer climbing hard in its wake. April and May are the most volatile weeks of the year, with the region's hail and tornado risk peaking then. Summer settles under a stagnant ridge with weeks of flat readings above 100 degrees. Remnant moisture from Gulf tropical systems occasionally reaches this far north in September, giving multi-day slow declines that feel quite different from the abrupt frontal changes.
What this means for you
Dryline passages and blue northers both produce fast, large swings. Weather-sensitive people here get more out of a migraine tracker app that logs pressure continuously than from a once-a-day reading.
