The wider storm

Leftover boundaries from June 3 thunderstorms and diurnally driven MLCAPE up to 1500-2000 J/kg triggered rapid storm development in the mid-James River Valley by mid-to-late afternoon. These storms intensified due to 40-45 kts of effective shear, producing hail as large as baseballs.
