The episode as NWS PAH wrote it up.
Thunderstorms, including a few strong to severe storms, developed and spread east and northeast during the afternoon and evening. The storms developed along a cold front extending from northern Indiana southwest across central Illinois into southeast Missouri. Convergence in the vicinity of the cold front, where the environment remained moderately unstable, supported new thunderstorm development. Bulk wind shear was strong enough to support organized severe storm structures.

NWS Paducah, KY wrote its last area forecast discussion before the first event at May 9, 12:06 PM CST, 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 106 PM CDT Fri May 9 2014 .UPDATE... Issued at 106 PM CDT FRI MAY 9 2014 Quick time adjustment to the text, grid, tabular products to reflect the slightly faster eastward adjustment (by an hour) of the convection moving into our western sections of the WFO PAH CWA and to also include the Severe Thunderstorm Watch number 135. UPDATE Issued at 1117 AM CDT FRI MAY 9 2014 Interim morning update to reflect marked changes in PoP, weather, sky cover, and temperature/dewpoint to reflect recharging of atmosphere between early morning MCS and new convective activity on central and southern Missouri. && .SHORT TERM...(Today through Sunday night) Issued at 234 AM CDT FRI MAY 9 2014 With the approach of a frontal system and attendant H5 trough, shower and thunderstorm activity will increase from west to east across the region today. With the flow aloft nearly parallel to the front combined with surface high pressure firmly planted over the southeast US, the front will have difficulty making it too far east over the next 18 to 24 hours. Latest guidance shows the front moving into the western sections of our CWA this afternoon, becoming quasi-stationary over the northern sections by Saturday morning, then lifting back to the north as a warm front on Saturday. With the front forecast to be in the vicinity, precipitation chances are greatest today and tonight. There is a slight risk of a few storms becoming severe this afternoon with large hail and damaging winds being the main hazards. Precipitation forecast confidence rather low Saturday, Saturday night, and Sunday as our area will be in the warm sector and mid level temperatures not that impressive. Low level forcing will be negligible but ripples of mid level energy will continue to track across left-over deep moisture, and models not in the best agreement on where the moisture will be. Sunday night as the next weather system takes shape over the plains, the flow aloft turns more southwest forcing the ridging over the southeast to build northwest into our neck of the woods. This should limit any precipitation chances to the far northwestern and western sections of our CWA. Temperatures will stay at or above normal through the period. .LONG TERM...(Monday through Thursday night) Issued at 234 AM CDT FRI MAY 9 2014 To start out the long term period, we will be watching the evolution of an upper trough that will be positioned in the Rockies on Monday. As this feature slowly moves east, a sfc frontal boundary will be making its way toward the region. It is looking more and more that Monday might end up being dry as we wait for the incoming front. Best chances late in the day will be in parts of southeast MO and southern IL. There continues to be timing issues between the GFS and ECMWF, with the GFS continuing to be the faster model but looking back on previous runs, both models have slowed down a bit with timing. The ECMWF seems to keep a much stronger upper high in place over the southeastern states which slows down the progression of the aforementioned upper trough. The 12Z ECMWF barely has the front into the area by 12Z Tuesday, with precip knocking on our western door, while the 00Z GFS is showing a pretty stormy Monday night period going into Tuesday. The 00Z ECMWF is a bit faster but still not as fast as the GFS. The front continues to move east during the day on Tuesday and plan on keeping likely pops right now as there seems to be good consistency for that day so far. When to exit the precipitation though, will be another story. The 00Z GFS moves the activity out of the area Tuesday night while the slower ECMWF takes until Wednesday morning to dry us out. Plus, the 00Z ECMWF indicates another wave of precipitation coincident with the main upper trough as it moves through Tuesday night into early Wednesday. These timing issues also play a big role in determining temperatures. The faster GFS is indicating that the colder air will filter in as early as Tuesday, making for a much cooler day than the slower ECMWF would suggest. Wednesday's temps though will be a bit easier since we should have the colder air mass into the area by then. With 850 mb temps in the single digits, we will definitely feel like fall has returned briefly, as we struggle to get out of the 60s in some places. Looking at some of the CIPS analog guidance, there is even more confidence that highs in the 60s appear likely with this colder air mass coming in. Highs in Thursday will be even more of a challenge since the GFS turns winds around to southerly, which warms us up, but the ECMWF maintains a colder northwest wind. && .AVIATION... Issued at 1244 PM CDT FRI MAY 9 2014 Rather convoluted set of TAF's for the WFO PAH forecast area trying to encompass the departing MVFR ceilings and the approaching MVFR/IFR ceilings and MVFR visibilities with the new shower and thunderstorm activity later this afternoon and this evening. An even longer duration of MVFR ceilings and visibilities are expected in the vicinity of the stalling cold front, especially from KPAH and KEVV eastward. Not particularly fond of using more TEMPO groups, but do not wish to keep longer periods in place of lower ceilings and visibilities as a prevailing group when possible. && .PAH WATCHES/WARNINGS/ADVISORIES...
