Typical Tornado Paths

1. Southwest → Northeast (most common)
   Storm systems often develop over Arkansas or Mississippi and move northeast across western Tennessee into Kentucky.

2. West → East or WSW → ENE
   Associated with strong squall lines or cold fronts coming from Missouri.

3. South → North / NNE
   Occurs when very moist air flows northward from the Gulf of Mexico.

These paths generally follow the movement of large storm systems across the central United States.

Geographic Factors That Increase Tornado Risk

1. Warm Moist Air from the Gulf

Warm, humid air moves north from the Gulf of Mexico and collides with cooler, drier air from the central U.S.
This strong contrast creates atmospheric instability needed for severe thunderstorms.

2. No Major Mountain Barriers

Between the Great Plains and the Mississippi Valley there are few major mountains.
Air masses can move freely, allowing warm southern air and cooler northern air to interact easily.

3. Mississippi River Valley

The Mississippi River valley helps maintain high low-level humidity and can enhance wind convergence, which supports strong storm development.

4. Strong Wind Shear

The region often has strong vertical wind shear:

• near the ground: warm moist winds from the south

• higher in the atmosphere: faster winds from the west or southwest

This shear allows thunderstorms to rotate and form supercells, the storms most likely to produce tornadoes.

5. Position Relative to the Appalachians

The Appalachian Mountains lie to the east and do not block storms moving from the west.
Instead, storms can continue across the region with little terrain disruption.

✅ Summary:
Northwest Tennessee and southern Kentucky have frequent tornadoes because they sit where warm Gulf moisture, cool continental air, strong wind shear, and open terrain combine—part of the southeastern U.S. tornado region often called Dixie Alley.
