The episode as NWS PAH wrote it up.
Scattered thunderstorms formed ahead of a weak cold front and an upper level disturbance as they moved southeast across the mid and upper Mississippi Valley. Isolated severe thunderstorms developed early in the afternoon over southern Illinois. During the hottest and most unstable time of day, storms consolidated across southeast Illinois into western Kentucky. Once the storms consolidated into clusters, damaging winds became the primary severe weather hazard. The storms occurred in a moderate to strongly unstable atmosphere, with mixed layer capes of 1500 to 3000. Effective wind shear values ranged from 25 to 35 knots.
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 Aug 6, 1:39 PM CST, 2 hours 18 minutes earlier.
Area Forecast Discussion National Weather Service Paducah KY 239 PM CDT Tue Aug 6 2019 .SHORT TERM...(Tonight through Thursday night) Issued at 238 PM CDT Tue Aug 6 2019 Ongoing threat for at least isolated severe thunderstorms over portions of southern IL/sw IN/nw KY and se MO exists as conditions have become very unstable with SBCAPEs running up from 4000-5000 J/KG over the current severe thunderstorm watch area. In addition, a weak mid level pertabation embedded within a broad nw flow regime is expected to enhance effective bulk shear into 30-35 kt range, which is about 10 kts higher than was expected yesterday. Though still a bit modest in normal conditions, this shear combined with the extreme instability could lead to an enhanced severe storm potential. Along with a hail potential, DCAPES running above 1200 J/KG are also supportive of damaging downburst winds in the stronger storms. Storms should continue to develop and push southeast through the watch area late this afternoon and into the early evening hours. Thereafter, overall weakening is expected and the severe threat should lower substantially. The rest of the overnight hours and much of Wednesday is expected to be generally precip free as weak high pressure moves in behind the departing system. Only caveat for Wednesday afternoon could be if another expected thunderstorm complex out over western MO Wed morning can either hold together or put out an outflow boundary to the se that could affect western portions of our se MO counties in the afternoon. Confidence in this scenario is fairly low at this time. Yet another weak cold front is expected to drop south toward the forecast area on Thursday within the continued broad nw flow aloft. This will spark the next chc for at least some sct thunderstorm activity over the region, most likely later in the day and into Thursday night. Once again, expecting some moderate to extreme instability to develop ahead of the front and 0-6 KM Bulk Shear is only expected to be near 30 kts. Thus, could end up with a situation similar to this afternoon, depending on the timing of the front. Bears watching anyway. .LONG TERM...(Friday through Tuesday) Issued at 238 PM CDT Tue Aug 6 2019 We will remain in northwest flow for the end of the week, with an upper level ridge just to our west. However, a weak front will be coming through the area from northwest to southeast Thursday evening into early Friday morning. Therefore, drier air will eventually be making its way southward into the area especially later in the day, which should aid in diminishing rain chances, especially up in the northern half of the area. Will maintain small chances in the southern areas given residual moisture. It should be rather quiet Friday night but the latest GFS indicates that some energy will be rounding the top of the upper level ridge late Friday night into Saturday morning. Depending on timing, the remnants of...or redevelopment of activity...is possible by Saturday evening which may even linger into Sunday, again depending on the timing of the storms. Due to these timing issues, PoPs will remain fairly low for now. By Sunday night into the first part of next week, it looks like the upper level ridge that was to our west, will finally slide east toward our area. This forces the more widespread activity to our north for a little while. Monday also looks to be the warmest day of the extended period with highs around 90 degrees. The flow flattens out with time, putting our area in a more favored trajectory for additional activity. Therefore it will remain unsettled enough to warrant slight chances for days 6 & 7. && .AVIATION... Issued at 1245 PM CDT Tue Aug 6 2019 Thunderstorm development will be possible early this afternoon near the I-64 corridor, with more organized thunderstorm activity possible late this afternoon heading southeast across the forecast area. Could be some hail and wind gusts 30-40 kts. Isolated severe storms will also be possible, through tough to call the exact placement and timing until development occurs. VFR conditions with light winds should be the rule outside of any convection. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.
