Event Summary - 27 April 2014 Quapaw and Octavia Tornado Event

A powerful upper level storm system moved into the Plains on Sunday April 27th 2014. This storm helped to produce an initial round of thunderstorms early in the morning out over western and central OK which moved into eastern OK and northwest AR during the day. Other storms developed farther east in AR as well. The morning storms left an outflow boundary that stretched from central AR to near Fort Smith and then arced back to the northwest into far northeast OK. A Pacific front/dryline mixed east into eastern OK by mid-afternoon…and was the focus for discrete storm development. This boundary wavered back and forth into the evening hours…helping to develop another more linear round of thunderstorms during the evening hours.
