Today's barometric pressure in Lexington, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Lexington's Bluegrass Region experiences the full range of Ohio Valley weather volatility. The city sits where Appalachian and Midwest weather patterns overlap, creating frequent and sometimes unpredictable barometric shifts.
Worst season for migraines: March through May and October through December. Lexington's Bluegrass Basin position catches both Ohio Valley weather systems from the north and Gulf moisture surging up the Kentucky River corridor. Spring severe weather and fall cold fronts produce the most dramatic pressure events across the rolling horse country terrain.
Common triggers in Lexington: Ohio Valley cold front passages, spring severe thunderstorm development, autumn temperature inversions in the Bluegrass Basin. Lexington sits at 980 feet in the Inner Bluegrass region, a gently rolling limestone plateau surrounded by the Kentucky River gorge and Appalachian foothills. The karst topography creates underground drainage patterns that keep surface humidity lower than surrounding river valleys, but the basin still traps air during inversions. The proximity to the Appalachian Mountains means systems from the west can stall as they encounter the mountain barrier, prolonging pressure events.
Typical pressure: Lexington averages 983 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 969 hPa. Swings of 12-18 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Lexington weather trigger migraines?
Yes. Lexington experiences 12-18 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Ohio Valley cold front passages, spring severe thunderstorm development, autumn temperature inversions in the Bluegrass Basin.
What time of year are migraines worst in Lexington?
In Lexington the most barometrically volatile stretch of the year falls in March through May and October through December. 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 Lexington's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
