Severe Weather

Scattered thunderstorms developed on Friday evening in a very unstable airmass. Although winds aloft were weak, enough instability existed to favor strong updrafts with large hail, and strong downdrafts with damaging winds. Licking County was the hardest hit, where two separate storms hit the Granville and Newark areas with hail up to the size of half dollars and extensive wind damage, including numerous trees down, some roofs off houses and several power poles and antennas blown down. Additional wind damage occurred in Fayette County and parts of west central Ohio.
