Tennessee borders eight other states: Kentucky and Virginia to the north; North Carolina to the east; Georgia, Alabama and Mississippi on the south; Arkansas and Missouri on the Mississippi River to the west. Tennessee ties Missouri as the state bordering the most other states.

Most of the state has a humid subtropical climate, with the exception of the higher mountains, which are classified as having a maritime temperate climate due to cooler temperatures[3]. The Gulf of Mexico is the dominant factor in the climate of Tennessee, with winds from the south being responsible for most of the state's annual precipitation. Generally, the state has hot summers and mild to cool winters with generous precipitation throughout the year. On average the state receives 50 inches (130 cm) of precipitation annually. Snowfall ranges from 5 inches (13 cm) in West Tennessee to over 16 inches (41 cm) in the higher mountains in East Tennessee.
