Wider weather episode

Multiple rounds of severe thunderstorm activity impacted portions of Oklahoma, mainly central and northern areas, from the morning of the 14th through daybreak on the 15th. An initial decaying complex of thunderstorms moved from southern Kansas into northern and central Oklahoma on the morning into early afternoon of the 14th. While this activity was non-severe for much of its journey across the WFO Norman Forecast Area, a brief uptick in intensity occurred after midday across southeastern Oklahoma, where sporadic damaging wind gusts and large hail were noted.

While a brief lull in convective coverage occurred through the early evening, a warming airmass near remnant thunderstorm outflow across west-central Oklahoma provided focus for the development of a lone intense supercell thunderstorm. This thunderstorm impacted portions of Custer, Blaine, Caddo and Washita Counties, producing a tornado and large to very large hail. As a broader synoptic trough impinged across the region later in the evening, more widespread coverage of severe thunderstorms occurred, yielding continued large hail and thunderstorm wind damage events across central and southern Oklahoma through daybreak on the 15th.
