NWS St. Louis, MO wrote its last area forecast discussion before the first event at Jun 26, 11:13 AM CST, 1 hour 38 minutes earlier.
Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 1213 PM CDT Wed Jun 26 2019 .SHORT TERM... (Through Late Tonight) Issued at 326 AM CDT Wed Jun 26 2019 CAMS like the HRRR depict at least widely scattered diurnal convection developing this afternoon with the best coverage across southeast MO as the atmosphere becomes unstable with daytime heating and as an MCV approaches from the decaying MCS over southwest MO early this morning. This convection should dissipate by late evening. The NAM model drops an MCS southeastward through northeast MO and IL late this afternoon and evening, while the 4 km NAM Nest is a little slower and further west with its MCS. Not real confident with the NAM solutions, but would not be surprised to see isolated to scattered showers/storms late this afternoon and early this evening across central and southeast MO and southwest IL. Slightly warmer and more humid conditions can be expected today and tonight as upper level heights gradually rise with south-southwest surface/low level winds. GKS .LONG TERM... (Thursday through Tuesday) Issued at 326 AM CDT Wed Jun 26 2019 Thursday and Thursday night appear dry at this time as upper level ridging builds over MO and IL with continued southerly surface winds as the synoptic boundary remains well north of our forecast area. Daytime highs may be slightly warmer compared to Wednesday, although it appears that we will be getting into a typical Summertime weather pattern with persistent temperatures generally slightly above normal for late June. The NAM model continues dry for our area with the exception of an MCS dropping south- southwestward into northeast MO and west central IL late Friday night as it forecasts a back-door type cold front approaching our area as a surface ridge builds into the Great Lakes region. Difficult to forecast location and timing of an MCS that far out in time so do not have a lot of confidence in this solution, especially since the operational GFS or ECMWF model does not forecast a similar backdoor front. The weekend looks mainly dry with the mid-upper level ridge centered over Iowa and northern MO. The chance of convection will increase by Tuesday as the upper level ridge shifts east of our area and as a mid-upper level trough approaches western MO on Tuesday. GKS && .AVIATION... (For the 18z TAFs through 18z Thursday Afternoon) Issued at 1151 AM CDT Wed Jun 26 2019 SPECIFICS FOR KCOU, KUIN: A remnant thunderstorm complex over southwestern MO was moving very slowly eastward at TAF issuance. This feature will support scattered SHRA/TSRA from around 26/21z through around 27/02z, but it is unclear whether SHRA/TSRA will extend far enough northward to affect KCOU. Similar concerns exist for KUIN due to a separate remnant thunderstorm complex which was located over extreme northwestern MO at TAF issuance. Otherwise, expect diurnal cumulus and light southerly to southwesterly winds. SPECIFICS FOR KSTL, KSUS, KCPS: VFR conditions are expected for the first 0-3 hours of the valid TAF period, but uncertainty increases after 21z. A remnant thunderstorm complex over southwestern MO was moving very slowly eastward at TAF issuance, and while it is expected to generate additional thunderstorms this afternoon, it is unclear how far north the convection might spread. VCTS from 26/21z - 27/02z seems appropriate at this time until the northern extent of the convection has been established. Otherwise, light southerly to southwesterly winds will persist through the period. Kanofsky && .LSX WATCHES/WARNINGS/ADVISORIES... MO...None. IL...None. && WFO LSX

It flooded several locations including a parking lot at Whitecliff Park. The flood waters moved two parked vehicles further down in the parking lot and one person had to be rescued from one of the cars. The other vehicle was unoccupied. Parts of Pardee and Grant Roads were briefly flooded as well. No deaths or injuries were reported.
Up to three inches of rain fell in a short amount of time causing flash flooding. Several roads around Pilot Knob were flooded including West Maple Street and Highway 221.
