Thunder Bay's location on Lake Superior creates changes in air pressure, with low pressure systems forming over the lake and moving east. This causes pressure to drop and rise frequently.
The city's high elevation and surrounding hills disrupt air flow, making it difficult for air masses to move smoothly, leading to changes in pressure. The landscape also traps cold air in the city during winter.
In winter, high pressure dominates, bringing cold air from the north. In summer, low pressure brings warm air from the south. Spring and fall see a mix of both, making pressure variable.
Thunder Bay has a continental climate, with large temperature and pressure swings between seasons. This leads to frequent changes in weather and pressure, making it important to check forecasts regularly.
