Heavy Rain/Severe Storms on December 20-21, 2013
 
Temperatures at 400 pm CST on 12/20/2013. A cold front sagged into Arkansas from the northwest on December 20th. Colder air behind the front was shallow, which made it difficult for the front to push through the terrain (the Ozark Mountains). The front eventually stalled.

Temperatures varied widely across the front. Readings ranged from the 30s in the far northwest to the 60s/70s across much of the region at 400 pm CST. This made the atmosphere unsettled, with scattered showers and thunderstorms popping up.

 

A storm system approached from the southwest, and interacted with the stalled front. Precipitation became more widespread, with areas of heavy rain resulting. In the far northwest (Benton County), it was cold enough for a brief period of freezing rain. Minor icing was reported. A storm system aloft ("L") interacted with a stalled front in Arkansas on 12/21/2013.

Precipitable water, or water vapor contained in a vertical column of at atmosphere, was well above normal (1 to 2 inches) at 700 am CST on 12/21/2013. Moisture levels were well above normal, with plenty of water to wring out of storm clouds.

Forty eight hour rainfall through 1200 am CST on 12/22/2013.

The heaviest rain fell in the southeast half of Arkansas, or along and north of the stalled front. Three to more than five inch amounts were common. Forty eight hour rainfall through 1200 am CST on the 22nd included 5.61 inches at Newport (Jackson County), 5.16 inches at North Little Rock (Pulaski County), 5.01 inches at Pine Bluff (Jefferson County), 4.72 inches at Little Rock (Pulaski County), 4.27 inches at Blytheville (Mississippi County), 4.04 inches El Dorado (Union County) and 3.71 inches at West Memphis (Crittenden County).

Given this much rain, flash flooding was a concern. Roads flooded in the Little Rock (Pulaski County) area. Numerous county roads were under water in Lonoke, Jackson and White Counties.

 

The intersection of Highways 224 and 226 were closed due to high water just south of Swifton (Jackson County). Three cars stalled along a flooded road near a hospital in Pine Bluff (Jefferson County). The westbound lane of Highway 36 caved in close to Georgetown (White County) and was barricaded.
Winter, flood, and severe headlines (watches, warnings and advisories) were posted across the middle of the country as of 1001 am CST on 12/21/2013.

Even with all of the rain, flooding along area tributaries (such as the Black, lower White and Ouachita Rivers) was mostly minor or expected to be minor.

 

A storm system ("L") quickly intensified during the afternoon and evening of 12/21/2013, with snow and ice to the north/west of the system and severe weather to the south/east.

Ahead of the front and south/east of the heavy rain area, well above normal temperatures helped energize developing storms. There was a lot of wind energy aloft, which drove storms quickly from the southwest to northeast.

 

The severe weather potential through the afternoon/evening of 12/21/2013. A fast storm movement usually increases the risk of strong to damaging winds. Winds also turned with height, which created rotation in a few storms and made tornadoes possible.

Just after 630 pm CST on the 20th, a brief tornado (rated EF1) was spawned just south of Redfield (Jefferson County). Several homes suffered roof damage, and numerous trees were uprooted or snapped. Fortunately, no injuries were reported. Minor damage (roof shingles removed, fences blown down, etc) was also reported in a neighborhood just northwest of Bryant (Saline County). This appeared to be caused by a very small feature such as a gustnado. 

The Little Rock County Warning Area was affected by at least two tornadoes during this event.

One tornado (rated EF1) cut through the Redfield (Jefferson County) area during the evening of 12/20/2013, with a stronger tornado (rated EF2) tracking through southern Desha County on 12/21/2013.

 

On the 21st, there was more severe weather during the afternoon and evening. Around 330 pm CST, there was a tornado (rated EF2) a couple of miles west of Hughes (St. Francis County). Three mobile homes were destroyed. There was one fatality, and three people injured (one seriously). Less than ten minutes later, semis were flipped over on Interstate 40 about nine miles west of West Memphis (Crittenden County).

There were at least three tornadoes counted in Arkansas on December 20th/21st, 2013. This brought the yearly total to 34 tornadoes.

This tornado tracked to around Halley (Desha County) before reaching the Yellow Bend Port (Chicot County) on the Mississippi River. After crossing the river, the tornado intensified (rated EF2) in Bolivar County, Mississippi and then finally dissipated. The path length was an impressive 41 miles.
