Pressure and weather in London
Cold fronts crossing Lake Huron can bring changing pressure and, with suitable wind and temperature conditions, lake-effect snow into the wider London area. Autumn and winter storm tracks are particularly important; summer humidity and thunderstorms create another distinct seasonal setting.
What this means for you
A snowy day in London may continue after the sharpest pressure change has passed. Pair current barometric pressure with snowfall forecasts and record symptom timing in a migraine tracker app, so a weather migraine pattern is not inferred solely from snow on the ground.
