Pressure and weather in Fairport
Fairport is a village in the town of Perinton, Monroe County, straddling the Erie Canal about nine miles east of Rochester. The Genesee River runs north through Rochester to empty into Lake Ontario, whose shore is only around twelve miles from the village, and the ground here is classic glacial drumlin country, low ridges of till trending north to south across the landscape. Proximity to Ontario is the single most important local factor. From late November until the lake ices over or cools sufficiently, cold northwest and west flow crossing the relatively warm water picks up moisture and dumps it inland as lake-effect snow, and Rochester routinely ranks among the snowiest metropolitan areas in the country. Lake-effect itself is not a large barometric pressure signal, but the cold air outbreaks that generate it arrive behind sharp cold fronts with pronounced pressure rises. The bigger swings come from synoptic systems: Great Lakes lows tracking through, Alberta clippers moving fast across Ontario province, and occasionally a coastal storm close enough to draw moisture inland. Spring adds frontal thunderstorms and autumn brings the wind-driven gales that stir the lake. Watching current barometric pressure across an upstate winter shows an unusually busy trace, and a barometric pressure forecast for Fairport is most valuable from November through March.
What this means for you
Can barometric pressure cause headaches? Upstate New York gets a steady stream of low pressure systems through the cold half of the year, and the barometer here climbs sharply behind each one as arctic air arrives off the lakes. Many residents find the repeated up-and-down of a Rochester winter harder than any single storm. Look at the barometric pressure forecast in Pressure Pal, a weather migraine tracker that displays pressure change today before the next lake-effect outbreak.
