Nashville Weather Radar - Live Doppler Map (TN)

🌦️ Nashville Weather & Live Doppler Radar Guide

Nashville is located in the fertile Central Basin of Middle Tennessee, bisected by the Cumberland River. The city experiences a humid subtropical climate with hot, humid summers and moderately cold winters. Middle Tennessee is situated in the active severe weather corridor known as 'Dixie Alley,' which is notorious for producing intense, long-track tornadoes and severe squall lines. Unlike traditional Great Plains tornadoes, storms in Dixie Alley frequently occur at night (nocturnal supercells) and during the autumn and winter months, making continuous Doppler radar monitoring critical for public safety across Davidson, Williamson, and Rutherford counties.

📡 NOAA NEXRAD Station: KOHX (Old Hickory / Nashville, TN)

Our interactive Nashville radar connects directly to NOAA's Level-III NEXRAD radar station KOHX, located at Old Hickory Lake northeast of downtown Nashville. Operating with S-band dual-polarization technology, station KOHX provides high-resolution reflectivity and storm-relative velocity scans to detect mesocyclone rotation, tornado debris signatures, and localized flash flooding.

🎨 How to Read Doppler Reflectivity (dBZ Scale)

Radar reflectivity measures precipitation density in decibels of Z (dBZ). Use this color reference when monitoring approaching storms on the Nashville radar:

⚠️ Seasonal Severe Storm Threats in Nashville

Middle Tennessee has two distinct severe weather peaks: spring (March to May) and autumn (November to early December). The region is vulnerable to nocturnal tornadoes embedded within fast-moving squall lines, severe hailstorms, and major flash flooding along the Cumberland River basin.
