Today's barometric pressure in Knoxville, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Knoxville's Tennessee Valley location between the Great Smoky Mountains and the Cumberland Plateau channels weather systems through the region. Mountain-valley pressure differentials create unique local effects not captured by regional forecasts.
Worst season for migraines: March through May and October through December. Knoxville's Tennessee Valley location between the Great Smoky Mountains and the Cumberland Plateau creates a natural funnel for weather systems. Spring severe weather is enhanced by orographic effects, while fall and winter bring rapid cold frontal passages through the valley corridor.
Common triggers in Knoxville: Tennessee Valley channeled storm systems, Great Smoky Mountain orographic precipitation events, temperature inversions in the valley trapping humidity. Knoxville sits at 900 feet in the Great Valley of East Tennessee, with the Great Smoky Mountains rising to 6,600 feet just 30 miles to the southeast and the Cumberland Plateau at 2,000 feet to the northwest. This valley-between-mountains geography traps moisture, channels weather systems, and creates temperature inversions that can persist for days. The Tennessee River flowing through downtown adds localized humidity and fog.
Typical pressure: Knoxville averages 985 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 973 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 Knoxville weather trigger migraines?
Yes. Knoxville 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 Tennessee Valley channeled storm systems, Great Smoky Mountain orographic precipitation events, temperature inversions in the valley trapping humidity.
What time of year are migraines worst in Knoxville?
In Knoxville 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.
How do I track migraine triggers in Knoxville?
Use MigrAid to log your attacks with one tap. The app automatically records barometric pressure, temperature, and humidity at the time of each migraine, then finds patterns between your attacks and Knoxville's weather conditions over time.

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 Knoxville's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
