The episode as NWS ICT wrote it up.
Two areas of storms developed during the evening hours and continued into the overnight in north central and south central Kansas. Strong and damaging winds were the main hazard with estimated wind gusts up to 75 mph. There was damage to trees and powerlines reported. A semi trailer was blown over on Interstate 70 as well. A few of the storms had hail from nickel to quarter size. These storms were efficient rainfall producers with flooding in the western portions of Saline County which closed many roadways as 7.45 inches fell in Brookville.

NWS Wichita, KS wrote its last area forecast discussion before the first event at Jul 21, 2:29 PM CST, 3 hours 7 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Wichita KS 329 PM CDT Mon Jul 21 2025 .KEY MESSAGES... - A strong to severe storm cannot be ruled out along I-70 this afternoon and evening. - Dangerous heat gradually waning by mid-week. - Periodic low storm chances late Wednesday through Friday. Best chances Thursday afternoon-night. - Heat likely to return this weekend into the beginning of next week. && .DISCUSSION... Issued at 328 PM CDT Mon Jul 21 2025 Morning elevated convection across northeast Kansas has left a diffuse outflow/differential heating boundary from approximately Salina to Chanute early this afternoon. This boundary extends further northwest into north-central Kansas where it meets the nose of a surface trough across western Kansas and far southern Nebraska. Additional storms have developed across north-central Kansas early this afternoon where these two features meet, and an outflow boundary from this convection will likely lead to additional development of showers and storms later this afternoon through tonight for locations mainly along and north of I-70. Shear is fairly modest (generally around 15 knots), but MLCAPE around 4000 J/kg could support a couple strong to severe storms along the I-70 corridor later this afternoon and this evening. Main concerns will be wind gusts around 50-60 mph, the potential for heavy rainfall, and frequent cloud-to-ground lightning. Surface convergence will wane tonight, and the mid-level baroclinic zone that was the catalyst for convection this morning will likely lift northward keeping rain chances well north of the CWA come Tuesday morning. Despite afternoon temperatures near the century mark Tuesday afternoon, gusty winds due to a tight pressure gradient along with surface winds being slightly west of due south should allow for moisture to mix out a bit better, and heat indices will struggle to get to or above 105 as result. However, we've elected to keep the Extreme Heat Warning for now given the longevity of heat indices of at least 105. The upper ridge moves eastward by Wednesday, and this will support afternoon temperatures being a little less hot than today and Tuesday. Again heat indices will struggle to reach 105 Wednesday afternoon given slightly "cooler" temperatures. Subtle mid/upper troughing will settle in across the central plains and will leave the door open for periodic storm chances Wednesday night through Friday. Though shear won't be stellar, 15 to 25 knots of 0-6 km shear, along with decent instability (despite fairly meager lapse rates) could support an isolated strong or severe storm or two, especially Thursday afternoon and evening. After Friday, long range global deterministic and ensemble models suggest a fairly robust, anomalously strong ridge developing across a large portion of the central CONUS. 50-70% probabilities of 500 mb heights exceeding the 99.5th percentile were noted on the EPS and GEFS later this weekend into early next week suggesting another prolonged period of hot temperatures across the forecast area. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1218 PM CDT Mon Jul 21 2025 Ongoing showers and storms across northeast Kansas have sent an outflow boundary south into southeast KS. This has resulted in northeast low level flow at KCNU. This boundary may become a focus for showers and storms in parts of the Flint Hills and southeast KS but confidence is low. Southerly winds are expected to return to southeast KS as we move into the afternoon hours. We may also see some storms drifting into central KS this evening but coverage is expected to remain isolated or widely scattered. Other isolated or widely scattered activity could develop late tonight after 08-09Z along the nose of the LLJ impacting parts of central KS including KSLN during the predawn hours on Tue. VFR will prevail at most locations with some southerly wind gusts to around 20 knots possible during the afternoon hours today and again on Tuesday. && .ICT WATCHES/WARNINGS/ADVISORIES... Extreme Heat Warning until 7 PM CDT Wednesday for KSZ032-033- 047>053-067>072-082-083-091>096-098>100. && DISCUSSION...JC AVIATION...MWM
