Fort Campbell's military presence dominates this city of 166,000, positioned where the Cumberland River flows through Tennessee's northwestern corner near the Kentucky border. Humid subtropical climate brings mild winters—January lows around 28°F—and hot summers pushing into the low 90s. The city receives 50 inches of annual rainfall, with spring tornado season creating anxiety from March through May. Rapid military-driven growth over recent decades transformed a small river town into Tennessee's fifth-largest city, creating infrastructure challenges and diverse transient population alongside established residents.
