The barometric pressure in Rochester, Minnesota averages around 30.12 inches. This is slightly lower than the national average. Weather patterns often influence pressure levels.
Rochester is situated in southeastern Minnesota. The city is near the Mississippi River. To the east lies the Bluff Country. This region features rolling hills and valleys.
These natural formations impact the atmospheric pressure. Air masses moving from the west are forced to rise. As they rise, they cool and condense. This creates precipitation. The Bluff Country's terrain can intensify weather systems.
Rochester's location also affects the movement of air masses. Cold Arctic air from Canada frequently moves south. Warm air from the Gulf of Mexico also influences the city's weather. The clash of these air masses contributes to the region's varied weather patterns.
