Late Season Snow April 20 2021

Overview

A strong cold front pushed through the region during the afternoon. Temperatures rapidly dropped 25+ degrees within 3 to 4 hours. In Paducah, it was 63 degrees at 4 PM, and by shortly after 7 PM it was snowing. This was a rare snow event for this late in the season. In fact, it was the latest measurable snow on record in Paducah and Evansville (dating back to 1937 and 1948 respectively). Behind the front, a band of rain quickly switched over to snow within 1 or 2 hours of starting at most locations. Despite the warm ground and air temperatures, the snow came down at a moderate to heavy clip to allow accumulations on grassy and elevated surfaces. Most of the region received anywhere from a light dusting to up to a half inch of accumulation. A few locations across southwest Indiana and western Kentucky picked up 1 to 1.5" during the evening. On the morning after, temperatures dropped below freezing across portions of the region. Cape Girardeau, MO set a record low of 29 degrees on April 21. Poplar Bluff, MO tied their record low of 31 degrees on April 21, previously set in 1940. This was tied for the 4th latest freeze on record in Poplar Bluff, dating back to 1897. The city hadn't recorded temperatures below freezing this late in the season since 1944, when they dropped to 31 degrees on May 7.
