Pressure and weather in Fergus
Regional lows can pull mild air north before replacing it with colder air from the northwest. In winter, winds crossing Lake Huron and Georgian Bay may carry snow squalls inland, with their reach changing as the wind turns. Summer thunderstorms bring another type of short-lived weather change over the river valley.
What this means for you
For a day near the Grand River gorge, compare symptom onset with the timing of the front rather than the depth of snow afterward. Pressure Pal offers weather context for that diary, not a diagnosis of the cause of head pain.
