Synopsis
April_27_Tornado_Outbreak_System.png|thumb|The tornadic system on April 27th, 2011]] The system responsible for the outbreak developed from a violent upper level trough, which was associated with an extratropical cyclone over the centeral plains of the United States. The outbreak was caused by a vigorous upper-level trough that moved into the Southern Plains states on April 25. An extratropical cyclone developed ahead of this upper-level trough between northeastern Oklahoma and western Missouri, which moved northeast.[15] Conditions were similar on April 26, with a predicted likelihood of severe thunderstorms, including an extended threat of strong to violent long-track tornadoes during the afternoon and evening hours; mixed-layer CAPE values were forecast to be around 3000–4000 J/kg, around east Texas, Louisiana and Arkansas. The storm mode on April 26 was predicted to consist of mostly discrete supercells during the afternoon and early evening, shifting over to a mesoscale convective complex, with more of a threat of damaging winds and hail during the nighttime hours.[16]
