One storm was responsible for five tornadoes (rated EF1/EF2) across a six county area in southern and eastern Arkansas on 01/22/2012.
In the picture: One storm was responsible for five tornadoes (rated EF1/EF2) across a six county area in southern and eastern Arkansas on 01/22/2012. Nearby storms produced isolated tornadoes (two of them) and baseball size hail.
 

Other storms were responsible for a tornado (rated EF1/9.4 mile path) south of DeWitt (Arkansas County) and another (rated EF1/0.8 mile path) just southwest of Coy (Lonoke County).

Fortunately, no lives were claimed by tornadoes. People had plenty of advance notice, with Tornado Warnings issued an average of 20 to 25 minutes before tornadoes arrived.

 

WSR-88D (Doppler Weather Radar) reflectivity images indicated a bowing structure (backward C-shaped line of storms) accelerating from DeWitt (Arkansas County) to Helena-West Helena (Phillips County) between 845 pm and 940 pm CST on 01/22/2012.
As storms accelerated into eastern Arkansas, they evolved structurally into bowing segments with damaging straight-line winds.

Winds over 100 mph were estimated north of Marvell (Phillips County) and on the west side of Helena-West Helena (Phillips County). A tree fell on a house, metal buildings were damaged, mobile homes were flipped and cars were hit by debris.

 

Some storms were accompanied by huge hail. Baseball size hail was reported at Brinkley (Monroe County), Griffith Spring (Lincoln County), Newport (Jackson County) and Tuckerman (Jackson County). There was golfball size hail at Oil Trough (Independence County) and Pinebergen (Jefferson County).

Up to baseball size hail pelted parts of Tuckerman (Jackson County) on 01/22/2011.

Growing Very Large Hail

In events like this when severe weather is extreme (multiple tornadoes), very large hail is not uncommon. On January 22nd, abundant moisture in the low levels of the atmosphere was driven aloft by powerful updrafts to create storm clouds and precipitation. Moisture encountered dry air overhead, with evaporation leading to rapid cooling** and a substantial layer of below freezing temperatures. This caused hailstones (ice) to form. Supercooled water (liquid in subfreezing air) accumulated on hailstones to help them grow. Updrafts prolonged the growth potential by suspending the hailstones.

** At 600 pm CST, a sounding (temperature and dewpoint profile with
    height) at North Little Rock (Pulaski County) indicated a freezing
    level of 11653 feet. The wet bulb zero level (freezing temperatures
    achieved through evaporation) was only 9406 feet. This created
    more room for hail growth aloft, and less room for melting below
    storm clouds.

 

Twenty four hour rainfall through 600 am CST on 01/23/2012. Rain was not excessive, but some areas picked up more than an inch of precipitation. Steprock (White County) had 2.25 inches, with 1.52 inches at Cabot (Lonoke County), 1.43 inches at Newport (Jackson County), 1.40 inches at Batesville Lock and Dam (Independence County) and 1.20 inches at Des Arc (Prairie County).

After storms crossed the Mississippi River, widespread severe weather continued into the early morning hours of the 23rd from portions of the Ohio Valley southward into Mississippi and Alabama. There was a large swath of wind damage and more tornadoes.
Twenty four hour severe weather reports through 900 am CST on 01/23/2012.
