Severe Storms/Heavy Rain on March 24-25, 2021
 
The surface map showed a strengthening storm system ("L") in Arkansas interacting with a warm front lifting to the north toward the Tennessee Valley at 100 pm CDT on 03/25/2021. Temperatures (dashed black lines) south of the warm front were in the 70s/80s, and it was very moist with mid 60s or higher dewpoints (darker green shading). This warm/humid environment fueled and energized severe thunderstorms during the afternoon and evening.

An outbreak of severe weather unfolded to the east of Arkansas on March 25th. An intensifying storm system in the southern Plains tapped into a warm and moist environment, and this sparked severe thunderstorms from the Tennessee Valley southward through Mississippi, Alabama, and Georgia.

 

There was a moderate to high risk of severe thunderstorms in portions of Alabama, Mississippi, and Tennessee on 03/25/2021. The forecast was courtesy of the Storm Prediction Center.

For the second time in about a week. there was a rare high risk of severe weather. The last time it happened was on the 17th. Before that, it didn't happen in March for nine years (since 2012). Violent long track tornadoes were expected.

 

 

In the video: The WSR-88D (Doppler Weather Radar) showed rain becoming widespread in northern and central Arkansas during the predawn hours of 03/25/2021.
 

Initially, it appeared that eastern Arkansas might be part of the outbreak. Instead, there were a few hailstorms from southwest into central portions of the state from the evening of the 24th into the wee hours of the 25th. Golf ball size hail was reported near Dierks (Howard County), with half dollar size stones at Foreman (Little River County) and west of Lono (Hot Spring County). Hail eventually turned into areas of heavy rain.

Before hailstorms got going in Arkansas, there was some severe weather earlier on the 24th in northern and central Texas. Isolated tornadoes were witnessed east of Hamilton, TX, northeast of Cranfills Gap, TX, and southeast of Roosevelt, TX. Hail bigger than baseballs pelted Haslet, TX and Junction, TX.

In Centreville, MS, a saturated ground made it easy for thunderstorm winds to uproot a tree onto a mobile home. A woman inside was killed.  

 

Supercells (storms with rotating updrafts) traveled long distances from Alabama into Georgia on 03/25/2021. One supercell spawned several tornadoes, and was responsible for significant structural damage on the south side of Birmingham, AL around 135 pm CDT and near Ohatchee, AL between 230 pm and 300 pm CDT.

As far as the outbreak, the first tornado (rated EF3) was confirmed about fifteen miles south of Tuscaloosa, AL around 1215 pm CDT on the 25th. By 135 pm CDT, the parent storm and a second tornado (rated EF3) were destroying homes about ten miles southeast of Birmingham, AL. The latter tornado lasted almost seventy minutes and tracked fifty miles.

About an hour later, the storm wreaked havoc (another tornado/rated EF3) in Ohatchee, AL, with substantial property damage reported and at least five fatalities.

Later in the afternoon (between 400 pm and 600 pm CDT), yet another storm and associated tornado (rated EF3) tore an eighty mile swath through areas near Centreville, AL, Columbiana, AL, and Calera, AL. Farther south, one more storm cranked out two tornadoes between 1000 pm CDT on the 25th and 1230 am CDT on the 26th. The first tornado (rated EF2) roughed up homes around Malone, AL and Motley, AL (a twenty eight mile track). Tornado number two (rated EF4) caused significant damage in Newnan, GA (a thirty nine mile track), with another death noted.

There were not as many tornadoes as on the 17th (more than two dozen twisters from southern Mississippi into central Alabama), but the tornadoes were stronger and lived longer.

In central Tennessee, a hailstorm went right through the heart of Nashville, TN. Hail ranged in size from nickels to ping pong balls.

 

Twenty four hour rainfall through 700 pm CDT on 03/25/2021.

As far as rainfall, it was enough (three to more than five inches) to cause flooding in northern Alabama and northern Georgia. Highway 65 was closed temporarily due to high water at Cullman, AL. Here in Arkansas, one to more than two inch amounts were common in the northern and central counties. The heaviest downpours (producing locally up to three inches) were in the Ouachita Mountains of the west (especially Polk and Scott Counties). Some places toward the Louisiana border got less than than a tenth of an inch.
