The wider storm

Significant clearing late in the morning resulted in the development of high instability across eastern Utah. This, paired with upper level support and ample moisture, produced strong to severe thunderstorms across the area in the late afternoon and early evening hours. Significant hail accumulation occurred in Green River and along I-70. Additionally, heavy rain occurred with storms which led to flash flooding across portions of Grand County.
