A significant outbreak of tornadoes occurred in two waves during the evening of the 8th and early morning hours of the 9th. The first wave occurred as multiple supercell thunderstorms developed across southern middle Tennessee and far north central Alabama. These storms moved east during the evening hours, producing ## tornadoes in north central and northeast Alabama.||A break in the activity was then followed by a line of thunderstorms that dropped southeast through southern middle Tennessee into north central and northeast Alabama after Midnight through the early morning hours. The line produced tornadoes in southern middle Tennessee, a couple of which continued into northeast Alabama. Additional tornadoes occurred with the line in far northeast Alabama.||In addition, locally heavy rainfall from the slow-moving supercells produced flash flooding during the evening of the 8th, with several roadways covered with or barricaded due to hazardous driving conditions. This primarily affected locations in southeastern Madison County, northern Marshall County, and southwest Jackson County.

A tornado began producing damage between Jordan Lane and Elton Road. Minor roof damage and downed large limbs were observed in this location. The tornado moved east, just south of Mastin Lake Rd, and crossed North Memorial Parkway. A concentrated path of large limb damage indicators was recorded along this path. The tornado lifted east of Lakewood Road.

A combination of NWS Storm Survey crews, drone imagery, and supplemental Worldview 3 satellite imagery determined that an EF-1 tornado tracked through southeast Huntsville just north of Governors Drive. All damage noted was from snapped tree limbs and uprooted trees along this track. The track continued across Monte Sano, past Dug Hill Road, lifting just before Watson Grande Way.

38 minutes of warning. NWS HUN issued a tornado warning for this county at 02:54 UTC, 38 minutes before the tornado touched down, in force until 03:45 UTC.

The county was under a tornado watch, issued at 03:11 UTC and running to 05:19 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 01:42 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
