Figure 3. Doppler velocity image of the supercell thunderstorm that hit Vilonia, Arkansas tornado. Note the clump of green colors lying right next to orange and red colors over Vilonia, showing that winds moving both towards the radar and away from the radar were located in close proximity to each other, the signature of a rotating mesocyclone in a severe thunderstorm capable of spawning a strong tornado.
The Arkansas Department of Emergency Management said three people also died in Arkansas’ Pulaski County and one in White County from tornadoes on Sunday. NOAA's Storm Prediction Center (SPC) had put much of Arkansas in their “High Risk” area for potential severe weather yesterday. It was the first “High Risk” outlook issued by SPC in 2014. According to The Encyclopedia of Arkansas History and Culture, the deadliest outbreak in Arkansas history occurred on March 21, 1952, when 112 people lost their lives. The most deadly recent outbreak was on March 1, 1997, which resulted in 25 Arkansas fatalities.
Outside of Arkansas, a tornado hit Quapaw, OK on Sunday, killing one person and destroying the fire station. In Kansas, the governor declared a state of emergency for Baxter Springs, where a tornado destroyed 70 homes and 20 businesses. In all, SPC logged 31 preliminary tornado reports from five states on Sunday, 107 reports of damaging winds, and 118 reports of hail. Also on Sunday, an 11-month old died from injuries suffered during a tornado on Friday in Chowan County, North Carolina. It was the first U.S. tornado death of 2014.
