The wider storm

With deep monsoonal moisture in place, as well as around 1000 J/kg of instability and some bulk shear aloft, widespread strong to severe thunderstorms formed across the Four Corners region. This resulted in multiple severe threats in eastern Utah which included large hail and flash flooding due to heavy rainfall rates in excess of 2 inches per hour.
