Pressure and weather in Crawfordsville
Crawfordsville sits in Montgomery County on the flat glacial till plain that covers most of central Indiana, with Sugar Creek cutting a narrow wooded gorge through the sandstone just west of town. There is nothing here to modify approaching weather, which makes the pressure record unusually clean and unusually large in range. The region lies where Gulf moisture flowing north up the Mississippi valley meets Canadian air pushing south, and the boundary between them parks over Indiana repeatedly through spring. Late March into June is the severe season, with strong lows crossing Illinois, dryline-fed squall lines arriving from the west and pre-frontal pressure falls that are steep and fast. Winter brings Alberta clippers and, less often, deeper Colorado lows with the heavier snow. Midsummer is hot and humid with overnight thunderstorm complexes drifting in from Iowa, and September and October are typically the quietest and most settled months of the year.
What this means for you
Flat terrain means what the synoptic chart shows is roughly what the barometer does, with no local terrain effects muddying the picture. That makes central Indiana a good place to test whether you really get a weather migraine or something else is driving the timing.
