Pressure and weather in Concordville
Concordville sits in the Piedmont countryside of Delaware County, in gently rolling terrain drained by Brandywine Creek on its way to the Delaware River, not far from where that river widens toward Wilmington and Philadelphia. Close enough to the Atlantic coast to feel its influence but far enough inland to avoid the worst of it, the area sees its biggest pressure drops from Nor'easters, the strong coastal lows that spin up along the Mid-Atlantic seaboard and pull cold air and heavy precipitation, rain or snow depending on the storm's track, into the region while pressure falls steadily over a day or more. Late summer and early fall bring a second source of sharp swings when tropical storm and hurricane remnants track up the Eastern Seaboard or ride the Appalachians' eastern flank, dumping heavy rain well after landfall. Winter also sees quicker-moving Alberta clippers slide through with a brief, shallower pressure dip and a dusting of snow. Summers are the calmest stretch, governed by a hazy, humid Bermuda high broken up mainly by afternoon pop-up thunderstorms, while spring brings a mix of both fast clipper-style systems and the season's first building coastal lows.
What this means for you
Concordville's most active pressure months run from late fall through late winter with Nor'easters, and again in late summer and early fall when tropical remnants track up the coast. Watching current barometric pressure ahead of both, and noting any barometric pressure headaches, can sharpen a personal migraine forecast for the region's two distinct storm seasons.
