Pressure and weather in Thunder Bay
Lake Superior moderates shoreline temperatures, while continental cold air and traveling low-pressure systems shape the wider forecast. Autumn and winter bring pronounced transitions between stormy periods and cold high pressure; spring warmth can arrive unevenly near the still-cold lake. Wind direction affects how strongly a shoreline outing feels the lake's influence.
