Pressure and weather in Lyndon
Lyndon sits in the Ohio River valley just east of Louisville, on rolling ground where the outer Bluegrass begins. The Ohio Valley is one of the great battlegrounds of American weather, and the barometer here behaves exactly like one. Warm, humid Gulf air pushing north up the Mississippi Valley meets cold continental air coming south, and the boundary between them frequently stalls along or near the Ohio River, which is why this area gets ice storms rather than clean snow; the January 2009 event remains the local reference point. A stalled front means the pressure oscillates in a sawtooth for days as the boundary shifts north and south instead of passing cleanly. Spring brings the year's most violent weather, with squall lines and occasional derechos crossing from the west, often overnight. Summer is hot, humid and stagnant in the river valley, with flat readings for long stretches and air quality degrading under the inversion. Autumn is the most settled season of the four.
What this means for you
Stalled boundaries produce repeated small oscillations that a once-daily check will miss entirely. A migraine tracker app logging continuously is the practical answer in this kind of pattern.
