Today's barometric pressure in Little Rock, 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 Little Rock...
Little Rock's position in the Arkansas River valley makes it a convergence point for Gulf moisture and northern cold fronts. The city experiences active severe weather seasons in both spring and fall, with each front bringing rapid pressure changes.
Worst season for migraines: November through March. Little Rock sits where the Ouachita Mountains meet the Arkansas River valley, in an active severe weather corridor. Winter fronts and early spring storms bring the most frequent pressure drops, peaking in February, when 54% of days see a 5 hPa drop. Summer is far calmer, at 7% of days or fewer.
Common triggers in Little Rock: Arkansas Valley severe thunderstorm development, Gulf moisture surges up the river corridor, rapid temperature drops during winter cold front passages. Little Rock occupies the north bank of the Arkansas River at the geological boundary between the Ouachita Mountains to the west and the Mississippi Delta plain to the east. This terrain transition enhances storm development as Gulf moisture collides with the mountain barrier. The Arkansas River valley acts as a moisture highway from the Mississippi to the interior, and the city's position at this geological boundary creates some of the Southeast's most frequent severe weather events.
Typical pressure: Little Rock averages 1005 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 992 hPa. Swings of 4-12 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Little Rock ranks #61 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
