Missouri is the crossroads of the American heartland, where the Mississippi and Missouri Rivers converge and eastern woodlands give way to western plains. From the gleaming Gateway Arch in St. Louis to the Ozark Mountains' ancient caves and the world-class barbecue pits of Kansas City, Missouri packs an extraordinary range of landscapes, history, and culture into a single state.

Missouri has a humid continental climate with four distinct seasons. Summers are hot and humid (average July highs of 87–92°F / 31–33°C statewide), with heat indices regularly exceeding 100°F. Winters are cold, with January averages of 38–42°F / 3–6°C, and ice storms are a periodic hazard from December through February. Spring and fall are the most comfortable seasons and the best times to visit. Tornado season peaks from April through June. The state sits at the intersection of dry western air and humid Gulf Coast air masses, creating highly variable weather patterns. Annual precipitation is 35–50 inches across the state, with the Ozarks typically receiving more than the northwest corner.
