The episode as NWS PAH wrote it up.
Isolated thunderstorms accompanied a strong cold front as it moved southeast across the lower Ohio Valley. The strongest storm produced a short swath of large hail west of Paducah. The atmosphere remained moderately unstable through the early morning hours. Winds aloft increased with the approach of a strong 500 mb shortwave trough from the northwest.
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 Sep 5, 1:30 AM CST, 3 hours 30 minutes earlier.
Area Forecast Discussion National Weather Service Paducah KY 230 AM CDT Tue Sep 5 2017 .SHORT TERM...(Today through tonight) Issued at 230 AM CDT Tue Sep 5 2017 Cold front currently bisects the CWA with ongoing convection across the mid section of the area. Main issue in the near term will be timing the exit of this and any further development through this morning. The precipitation is becoming a bit more post frontal, but all short term model solution indicate any lingering or redeveloping convection should be confined to the morning hours across the southern half of the CWA. Beyond 18Z, it looks dry across almost the entire region. Therefore, will taper off POPs through the morning from northwest to southeast. Will make last minute call on how exactly to handle POPs per latest radar. Cold air advection will be ongoing this morning and will continue through the day...as a large upper trough digs deeper into the deep south today. We will see much drier air also diving south across the area, taking the stickier air south of the region. 850mb temperatures will end up dropping into the single digits by the end of the day. We will see highs at least 10 degrees cooler today than yesterday with readings mainly in the mid to upper 70s. Light winds and mostly clear skies will result in lows plummeting into the lower 50s tonight. Would not be surprised see some upper 40s in the northern areas. .LONG TERM...(Wednesday through Monday) Issued at 230 AM CDT Tue Sep 5 2017 As some energy rotates down into the area on Wednesday, some cloudiness may result, especially in the eastern half, due to decent low level moisture. Any cloudiness will also help keep temperatures down as well, which will struggle to get out of the lower to mid 70s as it is. Cooler readings will be found in the eastern sections with southeast MO being the warmest. We should see rather cool readings again on Wednesday night, much like tonight, but there will be better chances that we will to drop into the upper 40s at more sites. The main upper trough will finally start moving east on Wednesday night into Thursday, which will mean less clouds to end the week. On Thursday and into Friday, we will see upper heights start to rise and the upper flow over the region weakens substantially by the weekend. We will see a gradual increase in temperatures toward the end of the week and into the weekend, with a good deal of sunshine as well. Surface high pressure, which will be centered over the region on Wednesday night into Thursday, will remain the dominant feature on the weather map for a few days, which will keep us dry. High temperatures will reach the upper 70s to near 80 degrees from Friday through Monday. && .AVIATION... Issued at 230 AM CDT Tue Sep 5 2017 Main area of convection is currently impacting KCGI and will likely reach KPAH over the next hour or so. KEVV is in the clear but scattered convection is still possible at KOWB for a while. Cold front is poised across the area and will continue sliding southeast with time this morning. We should see dry conditions in a few hours as well as winds becoming northwesterly at all sites. Winds should be aob 10 kts today and then drop down around 5kts this evening/overnight. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None. KY...None. &&
