Today's barometric pressure in Omaha, 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 Omaha...
Omaha's Great Plains location means wide-open exposure to weather systems moving across the continent. The Missouri River valley funnels weather patterns through the area, and spring severe weather season brings some of the fastest pressure drops in the Midwest.
Worst season for migraines: October through April, plus June. Omaha's position on the Missouri River bluffs places it squarely in the Great Plains storm track. Spring severe weather season brings supercells and tornadoes, while winter Alberta Clippers and Colorado lows produce rapid pressure drops with bitter cold.
Common triggers in Omaha: Great Plains supercell thunderstorms, rapid temperature drops of 30+ degrees during cold front passages, winter blizzard pressure gradients. Omaha occupies the Missouri River bluffs where the Great Plains begin their gradual climb westward toward the Rockies. The river valley creates a channel effect for weather systems moving along the Missouri corridor. Without significant terrain barriers in any direction, the city is fully exposed to Arctic air from Canada, Gulf moisture from the south, and dry air from the high plains to the west.
Typical pressure: Omaha averages 976 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 960 hPa. Swings of 7-16 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Omaha ranks #16 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
