St. Paul sits in a river valley along the Mississippi, creating cold-air pooling in winter that pushes temperatures several degrees below Minneapolis readings. For the victorian homes common throughout St. Paul, that means higher heating bills, cold drafts, and uneven room temperatures that no amount of thermostat adjusting can fix.
