Pressure and weather in West Lafayette
West Lafayette sits on the bluffs above the west bank of the Wabash River, opposite Lafayette, on some of the flattest glacial till plain in Indiana. There is nothing between the town and the Great Plains to slow a weather system down, so fronts arrive fast and the barometer moves in clean, steep lines rather than the drawn-out sags you get in sheltered valleys. Spring is the standout season: the Wabash Valley lies inside the corridor where Gulf moisture running north meets dry air spilling off the plains, and the April and May squall lines that result can drop pressure sharply over an hour or two. Winter belongs to Alberta Clippers cutting across from the northwest and, a few times each season, to the deeper Colorado lows that bring the region's heaviest snow. July and August often go flat, with humid stagnant highs and barely a millibar of variation for days.
What this means for you
The flat terrain means West Lafayette gets the full amplitude of every passing system with no local damping, so the barometric pressure forecast here is unusually predictive of what you will actually feel. Track a spring and an autumn in the migraine tracker app and see whether your worst days line up with the steep frontal falls rather than the slow ones.
