The wider storm

Weak warm advection initiated isolated convection in a low-shear, high CAPE environment. Slow moving storms made the most of strong initial updrafts to produce hail up to half-dollar size, followed by damaging wind gusts later in storm evolution.

Began near Big Spgs (43.0000, -96.5400).
