Today's barometric pressure in Shreveport, 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 Shreveport...
Shreveport's northwest Louisiana position puts it at the boundary between Gulf subtropical and continental climates. The city experiences active severe weather in spring and humidity-driven storms in summer, both bringing measurable pressure changes.
Worst season for migraines: December through March. Shreveport sits in the Ark-La-Tex region, where the Red River valley channels Gulf moisture northward. Winter fronts bring the most frequent pressure drops, from December through March, peaking in February, when 48% of days see a 5 hPa drop. Spring adds supercells and squall lines, while summer is far calmer, at 6% of days or fewer.
Common triggers in Shreveport: Red River valley severe thunderstorm development, Gulf moisture surges creating rapid humidity increases, rapid cold front passages with 25-degree temperature drops. Shreveport sits on the Red River bluffs in the northwestern corner of Louisiana, at the meeting point of the Gulf Coast lowlands, the Piney Woods, and the Great Plains. This geographic crossroads means the city experiences weather influences from all three regions. The Red River and Cross Lake add moisture to the local atmosphere, and the rolling terrain of the Ark-La-Tex provides just enough topographic variation to influence storm initiation and enhancement.
Typical pressure: Shreveport averages 1014 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 995 hPa. Swings of 4-11 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Shreveport ranks #65 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
