1 death, $10K damage
What happened
A strong storm system moved through the Ohio River Valley and central Appalachians on the 19th and 20th. Temperatures ahead of this system were warm, so precipitation started as rain. Around one inch of rain fell on the 19th. A cold front moved through late that evening, with temperatures dropping very quickly behind the front. This changed the precipitation over to a wintry mix of snow, sleet, and freezing rain before becoming all snow early on the 20th. ||The rain ahead of the system turned mostly into runoff due to already saturated soils. This caused minor flooding on some creeks and streams.||Heavy snow fell early on the 20th, with 6-7 inches near New Lexington in Perry County. In Morgan County, McConnelsville received 4 inches of snow. Amounts tapered off to the south and west with only 1-2 inches along the Ohio River. In Jackson County, a 34-year-old woman was killed in a single vehicle accident on Vega Road. The vehicle she was driving slid off the side of an ice covered road, dropped over an embankment and ended up on its top in a creek.
