Hail in Murray County, Oklahoma

The report was relayed through mPING.

This episode once again featured widespread severe convection across the central and southern extents of the WFO Norman Forecast Area from the afternoon of the 25th into early morning of the 26th. The background synoptic regime featured generally weak flow, with evidence of multiple weak embedded upper systems from northern Mexico into portions of the south-central United States. A persistent plume of strong instability, steep mid-level lapse rates, and sufficient deep-layer wind shear supported the development of transiently organized convection, including a few supercells during the early evening hours. However, generally weak steering flow and widespread thunderstorm initiation led to rapid and complex storm-scale interactions, limiting overall storm longevity and intensity. Still, numerous reports of large to very large hail were received, especially across portions of the southern Oklahoma City Metropolitan area. With numerous heavy and slow-moving thunderstorms, flooding reports increased across southern Oklahoma by late evening of the 25th and into early morning of the 26th.
