The episode as NWS PAH wrote it up.
Isolated to scattered thunderstorms developed during the heat of the day. A few of these storms briefly pulsed up to severe levels. The storms formed along and ahead of a weak cold front as it moved southward across southern Illinois. The storms were aided by a weak 500 mb shortwave trough over western Missouri.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Paducah, KY wrote its last area forecast discussion before the first event at Jul 15, 2:06 PM CST, 1 hour 9 minutes earlier.
Area Forecast Discussion National Weather Service Paducah KY 306 PM CDT FRI JUL 15 2016 .SHORT TERM...(Tonight through Sunday night) Issued at 211 PM CDT Fri Jul 15 2016 The models were pretty good this morning, modeling a quasi boundary across roughly the Oh River extended, and developing heat of day convection along it. This has more or less panned out, as synoptically, we'll see surface High pressure come in from the northwest, and drive the teleconnected boundary of low level convergence winds south and east thru the FA. Therefore, we'll extrapolate the scattered convection along it, and depart it by about mid to late evening, as the loss of diurnal fuel and departure of the boundary should spell the effective end of convection by overnight. Until then, there is a marginal risk, with locally heavy rain, lightning, and isolated strong cell capable of localized wind gusts. Over the weekend, the High is generally in control, and offers a slightly cooler/comfortable day Saturday, before returning some heat and moisture around its backside Sunday, as it migrates east, and heat indices popping again toward or into the triple digits. Any convection will be rimfire, generally to our south, and will be confined as such, with collaborative tweaks for the pic. .LONG TERM...(Monday through Friday) Issued at 305 PM CDT Fri Jul 15 2016 With this forecast issuance, the dominance of middle and upper level ridge hold in place early Monday, before retrograding and dampening as the sharp shortwave dives southeast across the WFO PAH forecast area Monday night through Tuesday evening. The ECMWF is becoming more pronounced with retracting the ridge further west, keeping the WFO PAH forecast in nearly north-south upper flow through Thursday. This appears to be overdone with respect to the Canadian, GFS, GFSEnsemble solutions and its influence was mitigated in the gridded forecast. Have kept with a greater impact of the ridge across the region following the passage of the shortwave on Tuesday. A drier solution appears to be a more acceptable collaborative solution versus the wetter ECMWF solution and was used with this forecast package. if you live in Southeast Missouri next week, it is going to be a nasty week for heat indexes in excess of 105 for nearly all the week. If a heat watch to be considered for a prolonged time period, roughly Sunday through Friday, Southeast Missouri would be the mostly likely candidate. May consider issuing a public information statement with heat safety rules for next week. Given the variability in the exact location of heat index values above 105 beyond Southeast Missouri, will hold off on any heat watch or advisory for the late weekend into next week. && .AVIATION... Issued at 211 PM CDT Fri Jul 15 2016 Heat of day convection will pose vicinity thunder chances thru mid evening. Amd's with active convection and associated restrictions to CIGS/VSBYS are anticipated, but the trending overnight should be dispersement with scattering decks and a return to VFR conditions. MVFR cu bases will develop again tmrw as daytime heating commences. && .PAH Watches/Warnings/Advisories... IL...None. MO...None. IN...None. KY...None. && LONG TERM...Smith
