Pressure and weather in East Rochester
East Rochester grew up along the Erie Canal on the flat lake plain that runs south from Lake Ontario before rising into the drumlin country and the Finger Lakes hills. Its weather is governed by the lake and by the storm track that funnels lows through the lower Great Lakes on their way to the St Lawrence. In late autumn and early winter Lake Ontario is still warm relative to the arriving Canadian air, and westerly flow sets up lake effect snow bands that can sit over one township for hours while the next is clear. Those events often follow a sharp cold frontal passage and a fast pressure rise. Deeper systems arrive from the Ohio valley and Alberta clippers race through in midwinter with modest moisture but abrupt gradients. Spring is slow to start because the cold lake suppresses convection near the shore, and September is usually the year's most settled month.
What this means for you
Great Lakes weather often pairs a fast pressure rise with a dramatic drop in temperature, so two possible triggers arrive together. A migraine tracker app that records both makes it easier to tell which one is doing the work.
