Overview
Saturday April 27th was a very volatile severe weather day across Kansas and Oklahoma. The stage was set with an abundance of low level moisture with dewpoints in the mid and upper 60s across the eastern half of Kansas. Low level wind shear increased as the day progressed which resulted in numerous rotating storms that produced several tornadoes across the Flint Hills into southeast Kansas. The strongest tornado was an EF-2, which occurred in Cowley County. Luckily there were no injuries or fatalities reported with these storms. As of May 3rd, we have confirmed 11 tornadoes from the April 27th event. Flooding eventually became a major issue as storms trained across southeast Kansas for several hours. Between April 25th and April 28th, many locations across southeast Kansas picked up between 7 and 10 inches of rainfall which sent the Neosho, Verdigris and Fall rivers into flood. |
