Overview


A lingering mesoscale convective vortex (MCV) moved through central and southern KS on the morning of Thursday, June 25th. A few locations, mainly across Harper County saw around 1 to 2 inches of rain from this event  with other locations across central and southern KS seeing around 0.5 inches of rainfall. Some more notable flash flooding had occurred earlier in the morning from that event across Pratt County. 

A warm front set up across central KS later in the afternoon and eventually, storms began to develop along it. As the front slowly tracked to the southeast through the evening, storms became more widespread and trained across the same areas. The hardest hit area was the Wichita metro and southern Sedgwick into northern Sumner County where a widespread 4 to 7 inches fell, most of it in a 2 to 3 hour period. Flash flooding reports from Wichita and surrounding areas were plentiful with dozens of reports of cars stalled and water over roadways. Homes along the creeks were also threatened and impacted by flood waters. Basement apartments were evacuated in west Wichita. Just after 10:30 PM KAKE News shared reports on social media from the following intersections of flooded roadways: 13th and Maize, 8th and West, 21st and 295th, Custer and Pawnee, 13th and Rock, Pawnee and Seneca, Central and Tyler. The number of flooded intersections only increased through the next several hours as rain continued. Some of the flooding was due to quickly rising creeks, including the Cowskin in west Wichita, which led to additional street and property flooding.
