The squall that matters is usually the one that shows up at two in the afternoon, while half of Port Huron is at work and the lake is busy filling every driveway in town. Midland Thomas Services LLC runs at that hour so the drive is open by the time headlights turn onto the street. Plowing, clearing walks down to bare pavement, salting the slick approach to the door — winter work, all of it, done while the weather is still going. St. Clair County storms come off open water and pile up fast, so timing counts as much as equipment. Coming home to a cleared drive is a small mercy, and it is worth doing well.
